LUGB-80 anti-corrosion nitrogen gas liquid flange connection vortex flowmeter explosion-proof pulse output type clamp pair insertion type with temperature and pressure compensation 485 communication

Description :

　　LUGB-80 anti-corrosion nitrogen gas liquid flange connection vortex flowmeter explosion-proof pulse output type clamp pair insertion type with temperature and pressure compensation 485 communication I. Product principle LUGB vortex flowmeter is mainly used for flow measurement of industrial pipeline medium fluids, such as gas, liquid, vapor and other media. Its characteristics are small pressure loss, large range, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring volumetric flow rate under working conditions. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can remain stable for a long time. The steam flowmeter adopts a piezoelectric stress sensor, which has high reliability and can operate within a working temperature range of -20 ℃ to+350 ℃. It has both analog standard signals and digital pulse signal outputs, making it easy to use in conjunction with digital systems such as computers. It is a relatively advanced and ideal flow meter. Widely used in the measurement of fluids in industries such as petroleum, chemical, metallurgy, and papermaking. This flowmeter has no movable parts, strong reliability, high accuracy, and long service life. It can measure the instantaneous flow rate and cumulative flow rate of liquids over a wide flow range. It is not affected by the temperature, pressure, viscosity, and composition of the medium, and is not blocked, stuck, easy to scale, resistant to high temperature and high pressure, safe and explosion-proof, suitable for harsh environments. And it can output remote pulse signals or current signals to connect with the PLC control system.
