SP-G 液体流量开关 1 9A2E21 说明说明书
19A2E21ManualSP-G 15 SP-G 2029A2E21FunctionThe SP-G liquid flow switch is designed for controlling and monitoring fluid flows. The function is based solely on the flow of the liquid and is not affected by the system’s static pressure; however, the system does require a basic pressure in excess of 1 bar.The switch is customised for applications where alarms for low flows are required while large flows can pass through without any increased fall in pressure. The switch has a variable through-flow area that increases as the flow increases.The through-flowing fluid lifts a spring-loaded pressure plate. The shaft on which the plate is mounted is mechanically connected to a lever that actuates a built-in micro-switch. Thedimension of the pressure plate controls the signal point. The contact changes positions at the ordered alarm point, which can be selected from 1.5 l/m to 30 l/m.If, for example, the switch is used to start a high-pressure pump or to open a valve, the flow may be allowed to increase significantly across the alarm point since the tray is lifted higher and the through-flow area increases continuously. Conversely, the switch can be installed in a flow system for e.g. protection against the dry running of a pump. Normally, at high flows, the fall in pressure across the switch is negligible. Nevertheless, the low flow alarm can be set to as low as 1.5 l/min since the through-flow area continues to decrease as the flow decreases and the plate moves downwards.Those parts that come into contact with the liquid are manufactured in dezincification-resistant brass, Teflon and stainless steel. Synthetic rubber gaskets.SP -G designsTwo different connection dimensions of the SP-G model are available: SP-G15 ½” female and SP-G20 ¾” male.The SP-G has a built-in micro-switch with alternating contact function.The outlet side can be rotated 90° or 180°, providing a number of alternative mountings for horizontal or vertical piping.SP-G mounting examples with inlet and outlet in different directions39A2E21SP -G installation instructions∙ Refer to the type plate and check that the desired alarm point in l/min and the liquid (e.g. water or oil) are correct.∙ Check that the amperage does not exceed the maximum load according to the switch contact specifications.∙ Make sure that the arrow on the switch housing is pointing in the direction of the flow. ∙ Make sure not to exceed the maximum operating pressure of 25 bar.∙ Make sure the liquid temperature does not fall below the minimum temperature or exceed the maximum temperature: –20 °C to +90 °C (optional +120 °C).∙ Mount the switch in the desired position. The outlet side may be rotated 90° or 180°. ∙ If there is a risk of freezing, the outlet side connection should point downwards in order to allow for drainage.∙ No straight sections are required upstream or downstream of the switch. ∙ Install a dirt filter at the front if there is a risk of clogging.SP -G specificationsFlow range:0 – 3.5 m/s.

流量开关s15000说明书
一，基本原理
热式流量开关是利用探测头温度变化的原理设计。
在探头内置发热传感器及感热传感器，并与介质接触。
测量时发热传感器发出恒定的热量，当管道内没有介质流动感热传感器接收到的热量是一个恒定值，当有介质流动时感热传感器所接收到的热量将随介质的流速变化而变化，感热传感器将这温差信号转化成电信号再经过电路转化为对应的接点信号或模拟量信号。

6、热式流量开关（可显示流量）。
7、亦可用插入式电磁流量计式。
那么流量开关该如何选型呢？
选择合适的流量开关除了根据自己需求功能选型之外，还应根据流体工况特性、安装要求、环境条件、经济性等因素合理选型。
①安装环境。
现场安装环境主要指测量管径大小、直管段长度、管道是否有振动、周围是否有强磁场干扰和高温辐射热等。
②安全性。
防止事故发生。
比如，测量腐蚀性介质时，根据腐蚀性强度选用合适的内衬材质，可燃性气体的环境应选用防爆型仪表。
③节能性。
流体经过流量仪表前后的压损，压损值越小节能性越好。
非接触式如超声波流量计、电磁流量计、弯管流量计无压损。
④流体特性。
流体特性主要指流体成分、温度、压力、黏度等。
根据实际情况逐步确认选型范围。
首先从成分（液体、气体、蒸汽、脏流污程度）区分，差压式流量计和涡街流量计基本适应以上流体。
⑤准确性和经济性。
一般本身其性能相对稳定、重复性好、使用寿命较长、量程比范围宽的流量计有利于后期增加工艺设备测量参数调节，从而减少投资。

Box 373) IN 46360 (4Dwyer‐Inst.coTDSchnual, Inc. 21246361) USAomINTRODUCTION / TABLE OF CONTENTS Step OneOffered in liquid and gas sensor types, the general purpose flow switch provides reliable low or no‐flow detection of relatively clean, non‐coating media with one 1A relay output. Liquid examples in clued water and acetic acid. Available in Polypropylene‐Ryton® or PVDF, the short flow sensor is used in pipe or ducting from ½” to 1‐1/2”, and the long flow sensor is used in 2” and up. The flow switch set point may be adjusted from 0.04 to 3 fps in liquids or 1 to 90 fps in gases as a low‐flow alarm. The flow sensor is best applied in applications with relatively constant temperatures.New Features∙Rugged Polypropylene‐Ryton® or PVDF sensor for corrosive liquids and gasses.∙Adjustable set point with LED for flow or no‐flow status indication.∙60VA relay selectable NO or NC via power supply wiring polarity∙Solid State sensor is not damaged by over‐ranging flow velocities.Make a Fail‐Safe System: Design a fail‐safe system that accommodates the possibility of switch and/orpower failure. Dwyer Instruments recommends the use of redundant backup systems and alarms in addition to the primary system. Adding a redundant alarm switch to the system is a cost effective means to prevent costly run‐dry issues.Table of ContentsSpecifications: (3)Dimensions: (3)Safety Precautions: (4)Introductions: (5)Configurations: (5)Technology: (5)Installation: (6)Wiring: (7)Wiring to a Dwyer Instruments: (7)Wiring the Relay output: (8)Wiring as a P‐Channel or N‐Channel Output: (9)Calibration: (10)Set Point: (10)Maintenance: (11)Cleaning Procedure: (11)Testing the Sensor (TDS Series Only): (11)Warranty: (12)SPECIFICATIONS / DIMENSIONS Step One Set point range: .04 to 3 fps / (.012 to .91 mps)Factory set point: .2 fps (.06 mps)Repeatability: ±.5% of set point @ fixed temp.Response time: 1‐10 secondsSet point adjust.: PotentiometerLED indication: Flow StatusViscosity range: 1‐200 centipoiseSupply Voltage: 14‐36 VDCConsumption: 70 mA maximumContact type: (1) SPST relayContact rating: 60 VA, 1A maxContact output: Selectable NO/NCProcess temp.: F: 32° to 140° / C: 0° to 60° Electronics temp.

Please refer to the part number located on the switch label to verify the exact model which you have purchased.User’s Responsibility for safety: Dwyer Instruments manufactures a wide range of flow switches and technologies, while each of these sensors is designed to operate in a wide variety of applications; it is the user’s responsibility to select a sensor model that is appropriate for the application, install it properly, perform tests of the installed system, and maintain all components. The failure to do so could result in property damage or serious injury.Proper Installation and Handling: Because this is an eclectically operated device, only properly trained staff should install and/or repair this product. Use a proper sealant with all installations. Never over tighten the sensor within the fitting, beyond a maximum of 80 inch‐pounds torque. Always check for leaks prior to system start‐up.Material Compatibility: The TDS series sensors are available in two different wetted materials. Models TDS1_2 are made of Polypropylene (PP) with Ryton® tips. Models TDS 2_2 are made of Polyvinylidene Fluoride (PVDF). Make sure that the model you have selected is compatible with the application liquid. To determine the chemical compatibility between the sensor and its application liquids, refer to an industry reference such as the Compass Corrosion Guide (available from Compass Publications).Wiring and Electrical: The supply voltage used to power the sensor should never exceed a maximum of 36 volts DC. Electrical wiring of the sensor should be performed in accordance with all applicable national, state, and local codes.Flammable, Explosive and Hazardous Applications: DO NOT USE THE TDS SERIES GENERAL PURPOSE FLOW SWITCHES IN HAZAROUS LOCATIONS.WarningThe rating for the relay is 120 VAC / 60 VDC @ 1A. For CE rated applications, the relay rating is 60VAC / 60 VDC @ 1Amp.Dwyer Instrument’s Thermal Dispersion flow switches are not recommendable for use withelectrically charged application liquids. For most reliable operation, the liquid being measured mayneed to be electrically grounded.The sensing tip of the sensor must always be submersed in the liquid and never exposed to air.The liquid temperature must remain constant and not change throughout the process.INTRODUCTION Step Three Configurations:Part Number LengthMaterial(body)Material(cable)TDS112 Short (3”) PP‐Ryton® PolypropyleneTDS122 Long (4.5”) PP‐Ryton® PolypropyleneTDS212 Short (3”) PVDF FEPTDS222 Long (4.5”) PVDF FEPTechnology: The thermal dispersion flow switches measure liquid temperature to determine changes in flow velocity. As fluid flows across the sensing tips, the temperature is reduced proportionately as a function of the flow rate. When a temperature or velocity shift reaches the user defined set point, the switch changes state indicating the appropriate flow condition (flow of no‐flow).Dwyer Instrument’s sophisticated electronics convert the temperature shift into a signal which indicates whether a flow or no‐flow condition occurs. Depending on how the sensor is wired, this signal may be wired for normally open or normally closed circuits.Dwyer Instrument’s Thermal Dispersion flow switches have no moving parts to clog or foul, making them suitable for a verity of applications, including non‐coating and non‐scaling liquids. The TDS series directly measure mass flow and can operate over board range of liquids from 0.4 to 1.2 specific gravity and 1 to 200 cp.Initializing Sequence for TDS series: Powering up the TDS series is different in liquid and air. When the flow switch is powered up while submersed, the TDS series will immediately indicate flow before switching to its correct state. When the flow switch is powered up in air, the TDS series will immediately indicate no‐flow before indicating its correct state. A time delay may be used to eliminate the initialization sequence. Dwyer Instrument’s thermal dispersion relay controllers feature a 0 to 60 second time delay for your convenience.Set Points: The TDS series flow switch set point is factory calibrated to 0.2 fps. To convert feet/sec to GPM, please refer to the chart below.Flow Rate vs. Velocity(gpm vs. fps)Installation Step FourThe TDS series flow switch must always be in contact with theliquid being measured. The flow switches feature a 3/4” NPTthreads which will allow it to be used with various types offittings. Be sure to check the insertion depth of the flowswitch in the fitting after it is installed. See the diagram to theright for the recommended insertion depth.The two tip of the sensor are to be perpendicular tothe flow (as seen to the right). Never mount the tipswith one in from t of the other.When using any type of fitting, the orientation as well as theinsertion depth of the flow switch in the pipe is critical. Seethe diagram to the right for the recommended orientation.Best location for installation will be along the top of the pipe.WarningThe flow switch tips have a thin plastic wall which may be damaged if dropped or installed improperly.The TDS series flow switch is designed for use in liquid. For best results, avoid installing the TDS series where bubbles are present or where the tips of the switch may be out of the liquid.The two temperature probes (tips) must always be perpendicular to the flow (see the flow at the same time).Supply Voltage: The supply voltage to the TDS series flow switch should never exceed a maximum output of 36 VDC. Use controllers or power supplied, with a minimum output of 14 VDC or maximum output of 36 VDC.Required Cable Length: Determine the length of the cable required between the TDS series flow switch and its point of termination. Allow enough slack to ensure the easy installation, removal and/or maintenance of the sensor. The cable length may be extended up to a maximum of 1000 ft, using a well‐insulated, 14 to 20 gauge shield four conductor cable.Wire Stripping: Using a 10 gauge wire stripper, carefully remove the outer layer of insulation from the last 1‐1/4” of the sensor’s cable. Unwrap and discard the exposed foil shield from around the signal wires, leaving the drain wire attached if desired. With a 20 gauge wire stripper, remove the last 1/4” of the colored insulation from the signal wires.Signal Output (Relay Switching):Allows the sensor to switch a small load on or off directly, using an internal 1A relay [120 VDC/VDC or (CE: 60 VDC/VDC)]. The NO/NC status is set by the polarity of the voltage feeding the red and black wires. The green wire is the common for the relay and the white wire is the NO or NC, depending on the polarity of red and black. Normally Open Wiring:Wiring to a Dwyer Instruments Controller:TDC Series ControllerTSP Series ControllerWiring the Relay Output: The TDS series relay output can be wired as a dry contact to a VDC or VAC power source. The TDS series does require 14‐36 VDC power to operate the sensor and switch the relay. All installations below identify a dry switch state as the normal position of the relay.Switching a Normally Open DC Load (Open during Flow, Closed during No‐Flow):The Red wire connects to Positive (+) of the powersupply and the Black wire connects to Negative (‐). TheLOAD can be attached to either the Green or Whitewires.

Reversing the Red and Black wires will reverse the polarity of the relay switch, but not the internal LED.1.Install the fitting and flow switch as described in the Installation section of this manual. Turn the flowswitch and controller power on and adjust the flow rate to the application setting. If the medium to be sensed is likely to be subject to any temperature variation, the flow switch should be set as the highest normal temperature likely to be encountered.2.Locate the potentiometer knob at the top of the flow switch. The red LED is visible through thepotentiometer. The adjustment is a single turn 270° potentiometer. The initial response time of the flow switch after adjustment is 1 to 10 seconds. Adjust the potentiometer in slow increments and wait for the response.a.LED is ON ‐ If the LED is on, slowly adjust the potentiometer counter‐clockwise, with a small flat headscrewdriver until the LED turn off.b.LED is OFF ‐ If the LED is off, slowly adjust the potentiometer clockwise. with a small flat headscrewdriver until the light turns on.3.Adjust the potentiometer back and forth where the LED is switching, eventually settling for where the LEDis OFF (this is the low flow state for the switch).a.If the flow is increased, the LED will remain OFF indicating a flow conditionb.If the flow is decrease, the LED will turn ON indicating a no‐flow condition.4.Verify that the new calibration is correct by lowering the system flow rate below the set point and check tosee that the red LED turns on. Then increase the flow rate above the set point and verify that the red LED turns off accordingly.TDS SERIES Flow Switch (Liquid Only) Potentiometer LocationMAINTENANCE Step NineMAINTENANCE/REPAIR: The TDS Series is not field serviceable and should be returned if repair is needed (field repair should not be attempted and may void warranty).General: The TDS series flow switch requires no periodic maintenance except to clean off any deposits or scaling from the sensor tip as necessary. It is the responsibility of the user to determine the appropriate maintenance schedule, based on the specific characteristics of the application liquids.Cleaning Procedure:1.Power: Make sure that all power to the sensor, controller and/or power supply is completelydisconnected.2.Sensor Removal: Make sure that the flow is off and the pressure is down prior to removing the TDS seriesflows switch. Carefully, remove the sensor from the installation. Replace the sensor with a 3/4” NPT plug to insure that the liquid does not leak out during this procedure. Do not re‐install the TDS series if the threads are damaged.3.Cleaning the sensor: Use a soft bristle brush and mild detergent, carefully wash the TDS series flow switch.Do not use harsh abrasives such as steel wool or sandpaper, which might damage the surface sensor. Do not use incompatible solvents which may damage the surface sensor. Do not use incompatible solvents which may damage the sensor’s PP/Ryton or PVDF plastic body.4.Sensor Installation: Follow the appropriate steps of installation as outlined in the installation section ofthis manual.Testing the Sensor:1.Immersing the switch: Place the switch in a cup of water. Make sure the tips are submersed in the water.2.Power: Turn on power to the switch with Red to (+) and Black to (‐). You can reverse the polarity ifdesired.3.No‐Flow/Flow Test: With the switch setting still in the cup, wait until the Red LED turns ON (no‐flowcondition).a.Swirl the switch in the cup and wait until the Red LED turn OFF (flow condition).b.Stop swirling the sensor and let it rest in the cup waiting for the Red LED to turn ON again (no‐flowcondition).c.Repeat the above two steps.4.Relay Test: Connect a multimeter (set to read Ohms) to the White and Green Wires. Perform the aboveNo‐Flow/Flow test with the multimeter connect to observe the actuation of the relay.a.With Red to (+) and Black to (‐), the multimeter will read a small resistance during no‐flow (closedrelay) and OL during a flow condition (open relay).b.Reverse Polarity [Red to (‐) and Black to (+)] to see the multimeter read OL during a no‐flow state(open relay) and a small resistance during a flow condition (closed relay).The No‐Flow/Flow test determines if the switch is capable of sensing the changes between no‐flow and flow. The Relay test determines the ability of the relay to switch between a no‐flow and flow condition. This is the basic test to determine functionality of the sensor.MN890640A 11 of 12WARRANTY Step ElevenWARRANTY/RETURNRefer to “Terms and Conditions of Sale” in our catalog or on our website.

流量开关fr12b说明书
流量开关fr12b说明书FR12型电子式流量开关原理，结构。
基于热式原理,在封闭的探头内包含两个电阻,其中一个被加热作为探测电阻,另一个未被加热作为基准电阻、当介质流动时、加热电阻上的热量被带走。
电阻值被改变。
两个电阻差值被用作判断流速的依据。
FR12型电子式流量开关特点。
无活动部件、免维护、安装方便、一种型号适用多种管径要求。
开关量连续可调、极低的压力损失、结构紧凑LED显示流动趋势及开关状态。
FR12型电子式流量开关应用。
气液两用型，可用于气动和液压系统，可用于循环水、切削液及润滑油的断流监测，以及泵的空转保护。

FR12型电子式流量开关电气连接FR12型电子式流量开关LED功能及设定红色LED亮：断流或流速低于设定值，开关释放，或模拟量处于4Ma。
黄色LED亮：流速等于设定值，开关动作。
黄色及绿色LED亮：流速大于设定值，绿灯变亮越多表明流速越大。
将流量开关装好，使介质以需要监测的流速流动，调整电位计，使个绿色LED恰好变亮。
