The oval rotor principle has proven to be a reliable and highly accurate method of measuring flow. Along with the smooth oval rotors, exceptional repeatability and high accuracy over a wide range of viscosities and flow rates are features of the FTB3000 Series flow meter design.The low pressure drop and high pressure rating means the Omega FTB3000 Series flow meter is suitable for both gravity and pump (in line) applications.Please take a few minutes to read through this manual before installing and operating your meter. If you have any problems with the meter, refer to the maintenance and troubleshooting sections of this manual.If you need further assistance, contact Omega’s customer service department by telephone or fax for advice.2.SpecificationsService Fluids: Clean liquids, max particle size .125" Accuracy: ± 0.25% of reading or better above 100 cstk Repeatability:± 0.05%Flow Range:w/ Mag Coil Pickup 2 to 20 GPMw/ Hall Effect Pickup 0.02 to 20 GPMK-factor: 460 pulses per gallon (approximate)Operating Temperature:w/ Mag Coil Pickup: -268°C to +232°C (-450°F to +450°F)w/ Hall Effect Pickup: -40°C to +150°C (-40°F to +302°F)Operating Pressure: 3000 PSIG standardMinimum Fluid Viscosity: 100 cstkWetted Parts: 316 SS body and gears with peek gear seats Bearings: Shielded, self lubricating 440 SS ball bearings Connections:Flange Option: 1" MNPT STDPickup Coil: Magnetic Type or Hall Effect (6 to 24 vdc power) Calibration: 10-point calibration traceable to NIST @ 100 cstks3.Operation3.1PrincipleThe FTB3000 Series of positive displacement meters use a pair of smooth oval rotors to provide a reliable and highly accurate measurement of flow. The smooth oval rotors displace a precise volume of fluid which is passed through the measurement chamber during each revolution. The smooth oval rotor design along with the viscosity of the fluid provides a complete viscous seal within the measurement chamber.The unique patented design ofOmega’s Oval Gear meterincorporates two smooth ovalrotors 90 degrees out of phase.The phase relationship of therotors is maintained by twooval timing gears which areout of the flow path. The ovaltiming gears have a pitchdiameter equal to the outsidediameter of the smooth oval rotors.The flow through the meter measurement chamber follows the path of least resistance. Therefore no liquid passes through the center cavity between the rotors. The fluid is displaced from the inlet to the outlet via the area between the smooth oval rotors and the inner diameter of the meter housing.3.2Precautions▪Before use, confirm the fluid to be used is compatible with the meter and make certain that the operating conditions conform to the meter specifications.▪To prevent damage to the meter slowly fill the system with fluid (this will prevent damage that may be caused by air purge).▪Keep the flowrate within the meter ratings.▪Remove meter from the piping, replacing with a short pipe, when cleaning the piping system by flushing. Costly damage to the meter may result if the assembly is cleaned by flushing with the meter installed.4.Installation▪Use thread sealant on all pipe threads.▪Install the meter carefully to avoid pipe strains.▪The meter must be installed on the discharge side of the pump.▪In tank-head operation, the head of the fluid must be higher than the pressure loss of the meter.▪The flow direction must conform to the arrow mark on the meter body.▪The meter must be installed in the correct orientation (see figure below).▪Connect appropriate connector from pick-up from DCS or electronics.Pickup ConnectionsStandard MAGHall Effect(Open Collector) Redi-Pulse(Open Collector)A - Signal (+)B - Common (-)A - 8 - 30 Vdc (+)B - Common (-)C - Pulse OutputA - 3.5 - 24 Vdc (+)B - Common (-)C - Pulse Output5.Maintenance5.1GeneralThe Omega FTB3000 Series flowmeters do not require routine maintenance and do not contain any field serviceable or replaceableparts.5.2Trouble ShootingRefer to the following troubleshooting guide for assistance withpossible meter malfunctions:TROUBLE CAUSE REMEDYFluid will not flow through the meter ▪Meter installedwith incorrectorientation.Re-orientate the meter.▪Line to meterblocked.Clear line to meter.▪Insufficientdifferentialpressure.Increase upstreampressure.Reduced flow through the meter ▪Line to meterpartially blocked.Clear line to meter. ▪Insufficientdifferentialpressure.Increase upstreampressure.Meter readings inaccurate ▪Fluid flowrate istoo low.See “Specifications” formin and max flowrates. ▪Fluid viscosity toolow.Check fluidspecifications.▪Air in fluid.

Their small size and standard 3⁄4 NPT fittings make them suitable for new or existing applications. The LVU-230 models have a relay output along with a 316 SS or PVDF sensor and an integral miniaturized, encapsulated electronic control unit mounted in a cast aluminum, explosion-proof, watertight enclosure. The LVU-260 is a 2-wire, 4 or 20 mA output system.Both use an ultrasonic wave propagation sensor mounted in the liquid medium. The electronics generates a continuous wave ultrasonic signal that completely illuminates the liquid-sensing area. The absence of liquid in the sensing area causes the ultrasonic signal to dissipate, which the electronics senses as a “dry” condition (and provides a 4 mA output signal in the LVU-260). When liquid is present, the amplitude of the ultrasonic signal increases, indicating a “wet” condition. This signal is converted by the electronics and energizes the 10 A relay (LVU-230) or a 20 mA output signal (LVU-260). The LVU-230 electronics may be set to provide the control output to an alarm, pump, or other device on either a dry or wet condition.SPECIFICATIoNS Repeatability: 2 mm (0.08") typical Delay (on): 0.5 s Input Power: LVU-230: 115 Vac 50/60 Hz standard; 230 Vac 12 Vdc, or 24 Vdc (optional) LVU-260: 9 to 36 Vdc outputs: LVU-230: 10 A DPDT LVU-260: Low-level fail-safe: 4 ±1 mA dry; 20 ±1 mA wet; high level: 20 ±1 dry, 4 ±1 wet ¾ NPT THREAD Ultrasonic liqUid level switchesLVU-230S, shown smaller than actual size.Housing: NEMA 4/NEMA 7 watertight, explosion-proof enclosure, cast aluminum Class I, Group C and D, Class II, Groups E, F and G; and Class III, Division I and 2Sensor Material: L VU-230S, L VU-260S: 316 L SS L VU-230K, L VU-260K: PVDF Temperature: Sensor: -40 to 149°C (-40 to 300°F) Electronics: -29 to 77°C (-20 to 170°F)operating Pressure: Up to 1000 psig Mounting: 3⁄4 NPT standard Weight:453 g (1 lb)。

If you have any problems with the meter, refer to the maintenance and troubleshooting sections of this manual.If you need further assistance, contact your local Omega Representative or contact the Omega customer service department by telephone, fax, or email for advice.2Operation2.1PrincipleThe Omega FTB500 Series of Low Flowrate Meters has been developed to meet the need for a low flow measurement device for use with low to moderate viscosity clean liquids and for gas measurement applications.The Omega FTB500 Series of Low Flowrate Meters is a family of low flow rate measurement devices whose design is based on a Pelton Wheel-like rotor. The measured fluid is directed tangentially through a velocity nozzle against the rotor causing it to spin. The pickup coil senses the spinning motion of the rotor through the housing and converts it into a pulsing electrical signal. Summation of the pulsing electrical signal relates directly to the total flow, while the frequency is related to the flow rate.2.2Precautions♦Do not drop the meter. Dropping the meter may result in damage to the meter housing and/or internals.♦Do not operate the meter at flowrates greater than the maximum flowrate marked on the meter. Operating atflowrates greater than the maximum flowrate may over-spin the meter. Over-spinning may result in damage tothe meter.CAUTION:Avoid over-spinning the meter. Over-spinning the meter may result in damage to the meter internals and lead to meterfailure.3 InstallationUpon receipt of the flowmeter carefully inspected it, checking for any indications of damage which may have occurred during shipment. Inspect all packing material carefully for parts or components which may have been packed with the shipment. Refer to the packing list/invoice for a detailed list of items included in the shipment.3.1 General PipingThe Omega FTB500 Series of Low Flowrate Meters is capable of sensing fluid flow in one direction only. The meter housing is marked by a flow direction arrow to indicate the direction of flow through the meter. The meter must be installed in the piping in the correct orientation to ensure the most accurate and reliable operation. Care should be taken in the proper selection of the mating fittings. Size, type of material, and pressure rating should be the same as the flowmeter supplied.When it is expected that flow will be intermittent, the meter should not be mounted at a low point in the piping system. Solids which settle or congeal in the meter may affect meter performance.In order to achieve optimum electrical signal output from the flowmeter, due consideration must be given to its isolation from ambient electrical interference such as nearby motors, trans-formers, and solenoids.A typical flowmeter installation is shown below:Blocking and Bypass valves should be installed if it is necessary to do preventive maintenance on the flowmeter without shutting down the flow system. The Bypass valve can be opened before the Blocking valves are closed allowing the flow to continue while removing the turbine flowmeter for service.BYPASS RUN METER RUNIMPORTANT: All flow lines should be purged prior to installing themeter. To prevent possible damage to the meter, install themeter ONLY in flow lines that are clean and free of debris.Upon initial start-up of the system a spool piece should be installed in place of the flowmeter so that purging of the system can be performed to remove all particle debris which could cause damage to the meter internals. In applications where meter flushing is required after meter service, care should be taken as to not over-spin the meter, as severe meter damage may occur.CAUTION:Avoid over-spinning the meter. Over-spinning the meter may result in damage to the meter internals and lead to meterfailure.3.2Strainers/FiltersThe Omega FTB500 Series of Low Flowrate Meters is designed for use in a clean fluid service. However, the service fluid may carry some particulate material which would need to be removed before reaching the flowmeter. Under these conditions a strainer/filter may be required to reduce the potential hazard of fouling or damage that may be caused by foreign matter.METER SIZE MESH SIZE PARTICLE SIZE(Maximum)¼" to ½"100 .00555/" to 1¼"70 .00881½" to 3"40 .015If a strainer/filter is required in the system, it should be located upstream of the flowmeter taking care that the proper minimum distance is kept between the strainer and flowmeter.3.3Installation KitsInstallation kits for the Omega FTB500 Series of Low Flowrate Meters consist of two lengths of appropriate tubing cut to a length appropriate for the upstream and downstream straight pipe run with appropriate end fittings.4Maintenance4.1GeneralPreventive maintenance for the Omega FTB500 Series of LowFlowrate Meters consists of a thorough general inspection.Remove the meter from the service line and take to a clean workarea. Use the following procedures and exploded component views to remove, inspect, and reinsert the flowmeter internals.4.2Disassembly1.Hold the meter securely using a vise. Meter orientationshould be such that the threaded plug is facing up. Useextreme care not to damage the meter housing or pipingconnections when placing in the vise.ing a large-blade screwdriver, turn the plugcounterclockwise to remove.3.To remove the shaft assembly, carefully thread a 10-32screw into the hole provided in insert. Thread the screwinto the insert until it bottoms out (finger tight only).4.Turn the housing over and slowly and carefully pull theshaft assembly and internals out of the housing. Takecare not to damage the shaft, rotor, and/or bearings.5.Remove and discard the gasket/seal.4.3Inspection & Repair1.Examine the flowmeter internals for signs of corrosionor fouling by foreign materials.2.Examine the shaft, rotor, and bearings for signs of wearand/or damage.3.If wear or damage is present, replace with new parts.NOTE: Clean all of the internals in an approved cleaning solution.Exploded View: C – Hard Carbon Bearing ModelsExploded View: BB - Ball Bearing ModelsRotorRotor4.4 Assembly1.Install any new parts.2.Guide the rotor and bearing assembly onto the shaft.Make sure the rotor is installed with the cup side of thePelton wheel facing the “IN” side of the housing.3.Place a new gasket on the insert. Always use a newgasket.4.Place the shaft assembly insert, gasket, and rotorassembly back into housing by inverting the housing tokeep gasket and rotor assembly in place.5.Install the threaded plug and tighten to 50 ft-lb.4.5Pickup Coil TestingTesting the MAG and MCP (RF) coils consists of measuring the resistance with an ohmmeter. Resistance measurements are to be made when there is no flow through the meter or with the coil removed from the meter housing.1.Measure the resistance between pin A and pin B. Theresistance should be approximately as listed in thefollowing table of some common coils.2.The resistance from any pin to the case should be greaterthan 1 Mohm.COIL DC RESISTANCE(Ohms)MC2PAHT 15.0 ±10%MCP3A 11.5 ±10%PC13-74G 1800 ±10%PC13-74S 1850 ±15%PC24-45G 1350 ±10%PC24-45S 1850 ±15%PC28-13G 120 ±20%PC28-14G 180 ±20%If either resistance measurement fails, replace the pickup coil.

F-85Principle of OperationThe OMEGA ®FTB600B SeriesFlowmeters feature an infrared, electro-optical transmitter and receiver molded into the flowmeter’s body, along with two miniature circuit boards to provide voltage stabilization and automatic IR output level control. The FTB600B automatically compensates IR light intensity for varying fluid opacity levels to ensure a strong square wave output signal. The flowmeter is suitable for clear, transparent and translucent fluids which must transmit infrared light. (Note: Not suitable for use with red liquids).The design of the FTB600B inherently bleeds off entrained gas, thereby improving overall accuracy. This flowmeter can be easily mounted into any position for greater system design flexibility, also saving time and installation costs. A strainer is included in models FTB602B through FTB606B.SPECIFICATIONSAccuracy: ±1% of readingRepeatability: ±0.1% of readingViscosity Range: 1 to 15 cStWorking Pressure: 150 psig at 79°C (175°F)ALL PLASTIC ULTRA-LOW FLOW SENSORSShown larger than actual size.Please refer to ordering chart below for specific unit dimensions.U ±1% of Reading AccuracyU S ix Flow Ranges,from 0.1 to 120 LPM U N o Flow StraighteningNeeded U T urn Down Up to 30:1U E asily Mountsin Any Position U H ose Barb orThreaded Connections AFor NPT Threads add suffix “-T” to model number, no additional charge.Ordering Examples: FTB602B , flowmeter with 0.3 to 9 LPM range.FTB605B-T, flowmeter with 2.5 to 75 LPM range, 11⁄4NPT fittings.FTB600B SeriesMaximum Pressure Drop @ Maximum Flow: @30 psi on all units (6.5 psi on FTB601)Ambient Temperature: -40 to 85°C (-40 to 185°F)Wetted Parts: PVDF (polyvinyldene fluoride) FKM O-rings (O-rings are not wetted on NPT units)Power Supply: 8 to 24 Vdc, 6 to 33 mA Output Signal: Square wave pulse Cable Length: 0.9 m (3')。

美国欧米茄超声波多普勒流量计
超声波多普勒流量计简介何为超声波多普勒流量计？超声波流量计（非侵入式多普勒流量计）是一种体积流量计，借助液体中的颗粒或气泡完成测量。
超声波流量计非常适合测量污水处理或任何导电性或含水性污浊液体的流量。
超声波流量计通常不适用于蒸馏水或饮用水。
用于洁净液体应用中时需要进行曝气处理。
超声波流量计还非常适合于低压降和低维护需求的应用。
PRINCIPLE OF OPERATION图 1： 超声波多普勒流量传感器基本原理为，利用超声波信号被运动中的悬浮颗粒或气泡（不连续）反射时，产生的频率偏移（多普勒效应）完成测量。
这种测量技术利用了声波在流动液体中传播时，被不连续的介质反射而改变频率这一物理现象。
将超声发射到充满流动液体的管道中，经液体中的不连续介质反射后，超声波的频率会稍稍发生变化，且该频率与液体的流速成正比（图 1）。
目前的技术要求液体中悬浮颗粒、气泡的直径至少为 100 微米的百万分之一百 (PPM) 或更大。
超声波多普勒流量计选型在选择超声波流量计或多普勒流量计前，需要考虑以下几大关键问题：∙ 液体中是否存在直径为 100 微米的百万分之一百的颗粒？∙ 是否需要手持式或连续性过程监视器？∙ 是否需要模拟量输出？∙ 流量计适用的最低流速和最高流速是多少？∙ 最低和最高过程温度是多少？∙ 最低和最高过程压力是多少？∙ 管道尺寸是多少？∙ 管道是否始终充满液体？设计类型夹持式超声波流量计包括单传感器和双传感器两种型号。
在单传感器型号中，发射和接收晶体置于同一传感器中，而将该传感器夹在管道表面的某一点。
耦合化合物通过超声手段将传感器与管道相连。
在双传感器型号中，发射和接收晶体分别置于不同的传感器中。
夹持式多普勒流量计不受存在于管壁本身，以及传感器与管壁之间的任何空气空间的影响。
如果管壁为不锈钢材质，管壁可将发射信号传输得足够远，以便使回波频率充分偏移而不影响读数。
在铜管、混凝土内衬管、塑料内衬管和玻璃纤维增强管中，也存在传导声波的不连续介质。

Originally developed for the secondary oil recovery market, the FTB-1400 is an ideal meter for liquid flow measurement on or off the oilfield. The meter features a 316 Stainless Steel housing and rotor support, CD4MCU Stainless Steel rotor, and abrasion-resistant tungsten carbide rotor shaft and journal bearings. These materials help the meter to maintain accuracy and mechanical integrity when measuring the corrosive and abrasive fluids found in many industries.Fluid entering the meter first passes through an inlet flow straightener that reduces its turbulent flow pattern. Fluid then passes through the turbine,causing the turbine to rotate at a speed proportional to fluid velocity. As each turbine blade passes through the magnetic field generated by the meters magnetic pick-up, an AC voltage pulse is generated. Thesepulses provide an output frequency that is proportional to volumetric flow.SPECIFICATIONSAccuracy: ±1% of reading for 1" and larger, ±1% of reading over the upper 70% of the measuring range for 1⁄2" metersRepeatability: ±0.1%Magnetic Pickup: 30 mV/P-P Materials of Construction Body: 316 Stainless SteelRotor:CD4MCU Stainless Steel Rotor Support: 316 Stainless Steel Rotor Shaft: Tungsten carbide Turndown Ratio: 10:1Calibration: Water (NIST traceable calibration) Pressure Rating: 5000 psi (maximum)Turbine Temperature: -101 to 177°C (-150 to 350°F); -101 to 232°C (-150 to 450°F) (with “-HT” option) End Connections: NPT, BSPP optionalFTB-1400 SeriesFTB-1425, shownsmaller than actual size.FTypical K-Factor Curve (Pulses per Gallon)P R E S SUR E D R O P K-FACTOR (PULSES/GALLON)K -F A C T O R (C Y C L E S /G A L L O N )O U T P U T F R E Q U E N C Y (C Y C L E S /S E C ) % O F V A L U E A T F L O W R A T E100%50%0% 10%50%100%FULL FLOW RANGE LINEAR FLOW RANGE1" AND LARGER TURNDOWN APPROX. 10:1½" TURNDOWN APPROX. 3:1L I N E A R I T Y (D E S I G N D E V I A T I O N )+1%+%-%-1%AVG.

For details on DPF701 meter, visit /dpf700 for details.K-FactorThe K-Factor represents the number of output pulses transmitted per gallon of fluid passing through the turbine meter. Each turbine has a unique K-Factor.However, turbine meters are not functionally consistent throughout the full flow range of the meter.There are several forms of “friction” inherent in turbine meters that retard the rotational movement of the turbine rotor. These frictional forces include: magnetic drag, created by electromagnetic force of pickup transducers; mechanical drag, due to bearing friction; and viscous drag, produced by flowing fluid. See charts on right.As flow increases, the frictional forces are minimizedand the free-wheeling motion of the turbine rotor becomes more linear (proportional to flow). The K-Factor becomes relatively constant and linear throughout the balance of the linear flow range. This is approximately a 10:1 turndown ratio from the maximum flow rate down to the minimum flow rate.Typical K-Factor Curve (Pulses Per Gallon)。

OMEGA磁流量计
磁流量计信息参考来源：美国OMEGA工业测量什么是磁流量计？磁流量计（磁流计）是不含任何移动部件的容积流量计，适用于测量污水处理或任何导电性或含水性污浊液体的流量。
磁流量计通常不适用于碳氢化合物、蒸馏水和许多非水溶液。
磁流量计还非常适合于低压降和低维护需求的应用。
工作原理磁流量计或磁流计按照法拉第定律的原理工作，即任意导体在与磁场垂直的方向上运动时，其两端感应的电压与该导体的速度成正比。
法拉第定律：E 与V x B x D 成正比，其中：E = 导体产生的电压V = 导体的速度B = 磁场强度D = 导体长度因为只有导体才适用法拉第原理，所以要利用此原理通过磁流量计测量流量，必须首先确保受测流体可导电。
根据作为磁流量计设计原理的法拉第定律，信号电压(E)取决于平均液体速度(V)、磁场强度(B)和导体长度(D)（这里即电极之间的距离）。
对于薄型磁流量计，磁场跨越流管的整个横截面（图1）。
如果将此磁场视为磁流量计的测量元件，则可以看到此测量元件在流量计的整个横截面上都与水流相接触。
对于插入式流量计，磁场从插入的探头处向外辐射。
磁流计选型选择磁流量计时需考虑的关键问题包括：•流体是否为导电性溶液或水溶液？•流体或浆体是否具有磨蚀性？•是否需要集成显示屏或远程显示屏？•是否需要模拟量输出？•流量计的最小流量和最大流量是多少？•最低和最高过程压力是多少？•最低和最高过程温度是多少？•流体与流量计浸入部分是否存在化学相容性？•管道尺寸是多少？•管道是否始终充满流体？插入式磁流计Omega Engineering 的插入式磁流量计采用标准的2" NPT 接头，也可适用于特定尺寸的管件。
FMG-550 系列专用于2" 到48" 的管件，流速范围为0.05 到10 m/s（0.15 到33 ft/s）。
FMG-550 系列提供一个模拟量输出以及一个集成显示屏，可显示流速和总流量。
FMG3000系列由耐腐蚀材料制成，适用于0.5 到8" 的管道。
