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.

for 200m 3/h the flow velocity v is:Example: v in ft/s Nominal pipe diameter 6”Desired measuring range1000 US GPMFrom the table we obtain for the flow velocity of 1ft/s a flow rate of 88.128 US GPM at 6”meter size;

A field calibration requires an accurate reference of velocity. The meter recalibration (G K modification) is also recommended after an exchange of electronics module.The value of the new calibration constant (G K new) can be calculated as follows:GK new = GK old x VaVmwith:Va = actual velocityVm = measured velocity (reference value)2.1.2 Current output adjustmentThe minimum value (i0%) and the maximum value (i100%) of the current output at normal operating conditions can be adjusted from menus 2.2.2. and 2.2.3.The actual values of the i0% and the i100% must be measured with an accurate milliammeter in a 4...20 mA loop.i0% must be in the range 3....12 mA. The factory setting is 4 mA.i100% must be in the range 12....21 mA. The factory setting is 20 mA.2.1.3 Time constantThe time constant value can be set in menu 2.2.4. This value represents the time needed to detect 63% of a simulated flow rate instantaneously raised from 0 to 100%.

科隆流量计说明书
科隆流量计说明书科隆流量计说明书篇一：科隆质量流量计仪表作业指导书科隆质量流量计仪表作业指导书一、目的：关怀和指导班组有效处理科隆质量流量计故障，对存在的危险进行分析，并采取相应的安全措施进行规避，以确保作业安全和质量。
二、适用范围：各装置中的科隆质量流量计三、接受标准：仪表维护修理规程四、工作原理：科隆质量流量计。
质量流量计以科氏力为基础，在传感器内部有两根平行的流量管，中部装有驱动线圈，两端装有检测线圈，变送器提供的激励电压加到驱动线圈上时，振动管作往复周期振动，工业过程的流体介质流经传感器的振动管，就会在振管上产生科氏力效应，使两根振管扭转振动，安装在振管两端的检测线圈将产生相位不同的两组信号，这两个信号的相位差与流经传感器的流体质量流量成比例关系。
计算机解算出流经振管的质量流量。
不同的介质流经传感器时，振管的主振频率不同，据此解算出介质密度。
安装在传感器器振管上的铂电阻可间接测量介质的温度。
五、常见故障现象分析、推断、处理：硬件故障若出现误差偏大，积算器显示不亮或不增值，显示器空白位等现象，其缘由：.安装不规范，可直接导致流量计零漂，如质量流量计安装在泵出口处较近，传感器支撑强度不够，连接法兰焊接不当产生应力信号，电缆受电磁干扰。
b.接线问题若出现显示器不亮现象，应检查积算器电源连线，若出现保险丝被烧，应确认输入电压与标准电压标称值，交直流形式是否一致。
又若出现积算器不随流量增加时，应检查积算器接线，若积算器装有正/反向程序，应检查流量计接线，因流量计接线不正确，会使积算器在反向流时不递增。
c.工艺介质改变若测量介质出现夹气，气化或两相流等现象，变送器会出现报警显示，严峻时，传感器停止工作。
d.变送器失效。
e.传感器失效。
f.管道吹扫问题。
软件问题质量流量计故障处理——对于刚校验完的流量计安装使用前肯定要留意在当前工况下的零点校验，必需保证流量计中充满介质后关闭两端截止阀才能零点标定，具体的方法有许多种，面板操作、手操器以及使用prolinkⅡ软件。
