vortex flowmeter with temperature and pressure compensation
Temperature and pressure compensation type vortex flow meter is a kind of new type intelligent flowmeter. It adopts new generation microprocessor and digital processing technology with grate improvement in technical performance, the anti-interference ability of the instrument is greatly improved, additionally, it has the function of storing data with time as label, and features excellent performance, reliable and stable metering, and the overall technology of the device keeps at domestic leading level. It is applicable to measuring the totalizing flowrate and instantaneous flowrate of liquid, gas and steam (includes compressed gas) as the ideal instrument for volume metering in industries such as petroleum, chemicals, metallurgy and urban water supply, gas pipe network and so on. This flowmeter meets the JJG1029-2007 “Code for Calibration of Vortex Flowmeter”, and the intelligent vortex flowmeter enterprise standard Q/KR371-2001.

Temperature and pressure compensation vortex flowmeter Features
Flange&body: integrally forged pieces, it will avoid break down into pieces. 100% SS304 material,we can provide material report.
Circuit Board: Digital circuit board,anti most of the supplier use analog circuit board,digital circuit board enjoy the advantages of anti-vibration and anti-interference.
Flow converter: Distinctive modular design, amateurs can operate, disassemble and assemble easily, it will avoid accident risks.
Welding: adopt the advanced fish scale technology,which makes the welding seam looks nice and smooth.
Japan OVAL technology with embedded-type sensor, triangular prism will not fall off, we already apply for patent.
Our medium temperature sensor can measure highest temperature around 350℃,normal it is -40~250℃
