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.

转子流量计
转子流量计转子流量计是一种用于测量流体流量的仪器，主要由转子、外壳、传感器、显示仪表等组成。
转子流量计适用于各种液体和气体的流量测量，广泛应用于化工、石油、冶金、水处理、食品等行业。
转子流量计的工作原理是根据转子的转动实现流量的测量。
当流体通过管道流过转子流量计时，流体的动能将使转子发生旋转。
转子上的叶片会在流体作用下产生推力，并且随着流体的流动而转动。
通过测量转子的转速和叶片数量，可以计算出流体的流量。
转子流量计具有以下特点：1. 精确度高：转子流量计的测量精度通常较高，可达到±0.5%~±1%或更高。
这使得转子流量计在工业生产中可以准确测量各种流体的流量。
2. 范围广：转子流量计可适用于多种流体的测量，包括液体和气体。
液体转子流量计的量程通常在0.1-10000L/min 之间，气体转子流量计量程则在0.03-1000m3/h之间。
3. 压力损失小：转子流量计的流通部分通常为直径较大的通道，因此流体通过时，流通阻力相对较小，从而使得转子流量计的压力损失也较小。
4. 抗磨损性强：转子流量计的转子通常采用不锈钢等材料制成，在长时间的运行中具有较强的抗磨损性。
这使得转子流量计具有较长的使用寿命。
5. 安装方便：转子流量计的安装较为简单，通常可以通过法兰连接或螺纹连接等方式与管道连接起来。
同时，转子流量计的体积较小，占用空间较少。
6. 易于维护：转子流量计结构简单，易于拆卸和清洗。
一般情况下，转子流量计仅需进行定期维护和校准，即可保持良好的工作状态。
转子流量计作为一种常见的流量测量仪器，广泛应用于工业生产和实验室等领域。
它能够准确测量流体的流量，帮助工程师和技术人员进行流程控制和质量监控，提高生产效率和产品质量。
在今后的发展中，转子流量计将继续优化和创新，以满足不断变化的流量测量需求，为工业发展做出更大的贡献。

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; for 1000 US GPM the flow velocity v is:v =200m 3/h x1m/s63.617m 3/hv = 3.144m/s v =1000 US GPM x 1ft /s 88.128 US GPM v = 11.35ft /sProtection classesto IEC 529/EN 60529 Sizing Guide 3.1The 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.For the expanding section,the optimum angle of expansion is α= 8°.ζat α= 8h d 1/d 2 1.2 1.3 1.41.51.6 1.71.81.92.0ζ10.0180.0230.02550.0280.030.03080.03150.03230.0332Expanding sectionPressure Loss CalculationSizing Guide 3.1Ordering GuideOrdering GuideOrdering Guide Ordering Guide 3.1Ordering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering GuideOrdering Guide 3.1Ordering GuideOrdering Guide。
