picked up either by two measuring elec-trodes in conductive contact with the medium or indirectly bycapacitive coupling.A signal converter amplifies the signal and convertsit into a standard analog signal (e.g.4 to 20 mA) and a frequencysignal (e.g.1 pulse for every US gallon or cubic metre of mediumflowing through the measuring tube).To ensure that the voltage is not short-circuited by the pipe wall,themeasuring tube is made of an electrically insulating material or fittedwith an insulating liner.Measurement is largely independent of the flow profile and other prop-erties of the medium,such as pressure,temperature,viscosity,density,consistency,electrical conductivity,and electrode contamination.Measuring systemsThe electromagnetic flowmeter consists of a primary head,that isinstalled in the pipeline,and a signal converter.The compact design has the signal converter mounted directly on theprimary head.For systems with pulsed d.c.field the primary head field coils whichgenerate the magnetic field are energized by a pulsed direct currentfrom the signal converter.The measuring signal is a squarewave voltage of the same frequency.These systems feature extremely small measuring errors. Electromagnetic flowmeters measure the volume flow of electricallyconductive liquids and slurries.Measuring principleAn electric conductor,in this case the electrically conductive medium,passes through a magnetic field.The voltage U induced in this mediumis directly proportional to the mean flow velocity v.Magnetic inductionB (magnetic field strength) and the distance between electrodes D(nominal pipe diameter) are constant.K instrument constantB magnetic field strengthv mean flow velocityD electrode spacingThe volumetric flow rate qv can be calculated according toTherefore:q v=U x D xπ(4)K x B4The reducing angle (α) should not exceed 8°(equivalent to α/2 = 4°),otherwise measuring accuracy may be affected.If the reducing angle is greater,a straight inlet section must be fitted between reducing socket and primary head.Expanding sectionPressure Loss CalculationFor the expanding section,the optimum angle of expansion is α= 8°.ζat α= 8°d1/d2 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 2.0ζ10.0180.0230.02550.0280.030.03080.03150.03230.0332Recommendations for installationSelection of meter sizeThe size of primary head should if possible be selected to provide a velocity of 2 to 3m/s or 6 to 9ft/sec.for the full-scale range. Minimum full-scale range is 0.5m/s or 1.5ft/sec.,maximum is 10 or 11m/s or 30 or 33ft/sec.,depending on flowmeter type.For fluids with a solids content,the velocity should be between 3 and 5m/s or 9 and 15ft/s to prevent deposits and minimize abrasion.Exact determination of flow velocityFor range setting purposes,the exact flow velocity can be determined using the flow table for each nominal pipe width.Example: v in m/sNominal pipe diameter DN150Desired measuring range200m3/hFrom the table we obtain for the flow velocity of 1m/sa flow rate of 63.617m3/h at DN150; for 200m3/hthe flow velocity v is:Example: v in ft/sNominal pipe diameter6”Desired measuring range1000 US GPMFrom the table we obtain for the flow velocity of 1ft/sa flow rate of 88.128 US GPM at 6”meter size;for 1000 US GPM the flow velocity v is:Flow tablesv = 1m/sMeter size Flow rate Meter size Flow rate DN mm m3/h DN mm m3/h2.50.017671250176.71 40.0452********.47 60.10179350346.36 100.28274400452.39 150.63617500706.86 20 1.131********.9 25 1.76717001385.4 32 2.89538001809.6 40 4.52399002209.2 507.068610002827.4 6511.94612004071.5 8018.09614005541.8 10028.27416007238.2 12544.17918009160.9 15063.617200011310 200113.10v = 1ft/sMeter size Flow rate Meter size Flow rate inch US GMP inch US GMP1/100.024********.801/80.03825012352.511/40.1530014479.813/80.3442516626.69 1/20.6120020979.21 3/4 1.3770241410.1 1 2.4480281919.211/4 3.8250322506.8 11/2 5.5080363172.6 29.7921403916.8 21/215.300485640.2 322.032567677.0 439.1686410027 561.2007212691 688.1288015667 8156.67Protection classes to IEC 529/EN 60529。
KROHNE FV-200系列流量计说明书
G-5The FV-200 Series meter utilizes vortex-shedding technology to provide a repeatable flowmeasurement accurate to 1% of full scale. The meter has nomoving parts, and any potential for fluid contamination is eliminated by the meter’s corrosion-resistant all plastic construction. The meter includes a compact 2-wire (4 to 20 mA) or 3-wire pulse transmitter (optional), contained within a conveniently replaceable plug-in electronics module. All electronics are housed in a corrosion-resistant enclosure. Unlike meters containing metal or moving parts, the FV-200 is perfect for aggressive or easily contaminated fluids. Applications range from ultra-pure water to highly corrosive chemicals and slurriesOperation of the FV-200 vortex flowmeter is based on the vortex shedding principle. As fluid moves around a body, vortices (eddies) are formed and move downstream. They form alternately, from one side to the other, causing pressure fluctuations. These are sensed by a piezoelectric crystal in the sensor tube, and are converted to a 4 to 20 mA, or pulse signal. The frequency of the vortices is directly proportional to the flow rate. This results in extremely accurate and repeatable measurements using no moving parts.Another advantage of utilizing aFV-200 vortex flowmeter is that there are no gaskets or elastomers in themeter. Therefore, one need only be concerned with the thermoplasticmaterial used in body construction.In a thermoplastic piping system, the material chosen for the flowmeter should match that of the pipe wherever possible.Many factors may affect the capability of a meter to measurethe flow of specific fluids accurately. Different solutions have varying ef-fects on meters. For instance, heavy particle suspension will wear down internal parts on some meters or cause sensing inaccuracies for non-obtrusive metering systems. For vortex flowmeters, high viscosities tend to dampen the formation of vortices and reduce the effective range. Particles and internal bubbles do not usually affect vortex meters. Slurries containing grit can wear down the bluff body over a period of time. Also, long fibers can catch and build up on the bluff,decreasing accuracy. Standard factory calibration is for tap water at32 SSU (1 CST) viscosity and ambient temperature. Viscosityabove 1 CST will raise the minimum readable flow rate, reducing SpecificationSMeasured: Liquidsconnection: 1⁄4 to 2 NPT threadWetted Material: PVC, CPVC or PVDF depending on model number turndown Ratio: 12.1 (except 1⁄4" meter size; 8.1)accuracy: ±1% of full scale, 4 to 20 mA or ±2% of full scale, frequency pulse (“-p” option)Repeatability: ±0.25% actual flow output Signal: 4 to 20 mA orfrequency pulse (source-sink driver; 1A source/ 1.5A sink; typical output resistance 10 Ω)power Supply: 13 to 30 Vdc enclosure: NEMA 4X (IP 66)Response time: 2 seconds minimum, step change in flowrangeability.

These hit the rotor from four directions and put it inmotion. The uniform loading of bearing from foursides causes the forces to cancel themselves out for the most part and wear is reduced to a minimum.The extremely hard bearing materials, sapphire and hard metal, ensure in addition an extraordinary life expectancy.The rotor speed is transmitted to an electrical pulse signal (frequency):•The FTB 372 is equipped with magnets onthe rotor. A Hall-Effect sensor detects the rotation of the rotor.A flow-proportional frequency signal (square wave signal) is provided.Safety instructions Series FTB 372- 6 -1.1 Intended useThe flow meter of the series FTB 372 may only be used for flow rate measurements or dosing of liquids. Never use them for gas measurements.WARNING! No safety component!The flow meter of the series FTB 372 is not a safety component in accordance with Directive 2006/42/EC (Machine Directive).

The electrical connection should only be carried out by a fully qualified electrician.General safety instructions:In all work, the existing national regulations for accident prevention and safety in the workplace must be complied with. Any internal regulations of the operator must also be complied with, even if these are not mentioned in this manual.You can mount the flow meter in any position. If it is installed into vertical pipes, the flow direction is preferably upwards. You must avoid a free outlet.Series FTB 372Important notes to installation and operationTechnical changes reserved - 7 -The arrow which is placed on the flow meter(→) shows the only permitted flow direction. For precise measurement, the length of the in- and outlet tubes must be observed(♑§ 3 "Important notes to installation and operation").The internal diameter of the in- and outlet tube must correspond with the internal diameterof the turbine flow monitor.The flow medium to be monitored should preferably contain as few solid particles aspossible. Present particles must not exceed a diameter of 0.63 mm. If necessary, install ascreen filter.Avoid absolutely the formation of gas bubbles or cavitation in the medium by takingproper measures.The material of the series FTB 372 is not suitable for monitoring oils. The strength of theused plastic parts would be considerably reduced.In order to clean the flow monitor of contaminations, flush the unit reverse to the flow direction (♑§ 7 "Cleaning of the flow meter").Suitable measures should be taken to prevent the medium from freezing.A possible blowing out of the device FTB 372 must take place only in opposite direction tothe flow.We recommend to use only screened connection cables. Connect the shield on one side (the wire ends) on ground.Attention:The union nut of the sensor (Hall-Effect-Sensor or inductive proximity switch) is sealed and must not be opened!When you still open this component, the fixation of the turbine system is disturbed and it will be damaged.Special safety instructions:Warnings that are specifically relevant to individual operating procedures or activities can be found at the beginning of the relevant sections of this operating manual.3 Important notes to installation and operationObserve the following instructions in order to achieve highest-possible measurement accuracy and specified output signal:• Before installing the turbine flow monitor flush the pipe carefully. You avoid a blocking ofthe turbine caused by particles from the pipe installation.• The installation position of the flow monitor is unreserved. If it is installed into verticalpipes, the flow direction is preferably from below upward. You must avoid a free outlet. • The arrow which is placed on the flow monitor (→) shows the only permitted flowdirection.Installation in pipingSeries FTB 372- 8 -•In order to achieve the best measurement accuracy, a straight tube in front of the flow monitor must be retained, min 10 x DN. Behind the flow monitor, a straight outlet tube of 5 x DN must be kept.The internal diameter of the in- and outlet tubes must correspond with the internaldiameter of the flow monitor. Before and behind the stabilization tubes, the line may be contracted or enlarged.In practice these instructions often can not be observed. Then the pulse rate and the measurement accuracy can be affected.•The flow medium to be monitored should preferably contain as few solid particles as possible. Present particles must not exceed a diameter of 0.63 mm. If necessary, install a screen filter!• The material of the series FTB 372 is not suitable for monitoring oils. The strength of the used plastic parts would be considerably reduced. •Attention:The union nut of the sensor (Hall-Effect-Sensor or inductive proximity switch) is sealed and must not be opened!When you still open this component, the fixation of the turbine system is disturbed and it will be damaged.4 Installation in pipingNow you can install the flow meter in the piping system which was prepared according to § 3.

1）标准孔板；2）标准喷嘴；3）经典文丘 里管；4）文丘里喷嘴；5）锥形入口孔板； 6）1/4圆孔板；7）圆缺孔板；8）偏心孔板； 9）楔形孔板；10）整体（内藏）孔板；11） 线性孔板；12）环形孔板；13）道尔管； 14）罗洛斯管；15）弯管；16）可换孔板 节流装置；17）临界流节流装置
工作原理
流量方程
式中 qm--质量流量，kg/s; qv--体积流量，m3/s; C--流出系数； ε--可膨胀性系数； β--直径比，β=d/D; d--工作条件下节流件的孔径，
m； D--工作条件下上游管道内径，
m； △P--差压，Pa； ρl--上游流体密度，kg/m3。
由上式可见，流量为C、ε、d、ρ、 △P、β(D)6个参数的函数，此6个参 数可分为实测量[d，ρ，△P，β(D)] 和统计量(C、ε)两类 。
在同样差压下，经典文丘里管和文丘里喷嘴的压力损失约为孔板与喷嘴的 1/4-1/6。而在同样的流量和相同的β值时喷嘴的压力损失只有孔板的30％-50％。
在相同阻流件类型和直径比情况下，经典文丘里管的必要直管段长度比孔板 与喷嘴的要小得多。
测量易使节流件沾污、磨损及变形的被测介质时，廓形节流件较孔板要优越 得多。
