涡轮机的类型液体flowmeter

turbine flow meterLZ-W(Y)series Turbine Flow sensor (Hereafter referred as sensor), based upon torque equilibrium principle, is a kind of flow rate meters. With its simple structure, light weight, high-accuracy, perfect repeatability, sensitivity and easy maintenance, the sensor is widely used in oil, petrochemicals, metallurgy, water supply and paper industry. It is the ideal instruments for flow measurement and energy conservation. Used with the display instruments, the sensor is applicable for measuring the one-impurities (fiber or particle) liquid in enclosed conduit that has no corrosive effect to stainless steel 1Cr18Ni9Ti, 2Cr13, corundum Al2O3 and cemented carbide. If special display instruments are equipped with the sensor, quantity control, excessive alarm and other functions will be obtained. The explosion-proof type (ExmIIT6) can be used under the circumstance of potential explosion hazard. The sensor is suitable for the medium of which the viscosity is lower than 5 × 10-6m2/s at working temperature. If the viscosity is higher than 5 × 10-6m2/s, the sensor should be calibrated on line before use.3.Basic Parameters Model Note LZ-W(Y)Nominal Diameter44mm,standard turbine meter flow range 0.040.25m3/hWide-range turbine meter flow range0.040.4m3/h66mm,standard turbine meter flow range 0.10.6m3/hWide-range turbine meter flow range 0.060.6m3/h1010mm,standard turbine meter flow range 0.21.2m3/hWide-range turbine meter flow range 0.151.5m3/h1515mm,standard turbine meter flow range 0.66m3/hWide-range turbine meter flow range 0.48m3/h2525mm,standard turbine meter flow range 110m3/hWide-range turbine meter flow range0.510m3/h4040mm,standard turbine meter flow range 220m3/hWide-range turbine meter flow range 120m3/h5050mm,standard turbine meter flow range 440m3/h Wide-range turbine meter flow range 240m3/h8080mm,standard turbine meter flow range 10100m3/hWide-range turbine meter flow range 5100m3/h100100mm,standard turbine meter flow range 20200m3/hWide-range turbine meter flow range 10200m3/h150150mm,standard turbine meter flow range 30300m3/hWide-range turbine meter flow range 15300m3/h200200mm,standard turbine meter flow range 80800m3/hWide-range turbine meter flow range 40800m3/hType Basic: +12V, pulse output high level≥8VLow level≤0.8VA420mA 2-wire current output, remote transmission typeBfield display type supplied by batteryCfield display/420mA 2-wire current outputAccuracy Class05accuracy class 0.510accuracy class 1.0Turbine TypeWwide-range turbineSstandard turbineMaterial S1Cr18Ni9TiL316L steel stainlessExplosion-proof Non-mark, non-explosion-proof typeEexplosion-proof type ExmCT6 or ExdBT6Pressure grad ordinary pressure tolerance (refer to the handbook)Hhigh pressure tolerance (refer to the handbook)
