Vortex flowmeter is mainly used for the flow measurement of medium fluids in industrial pipelines, such as gas, liquid, steam and other media. Its characteristics are low pressure loss, large range, high precision, and almost no influence of parameters such as fluid density, pressure, temperature, and viscosity when measuring volume flow. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable over a long period of time. The use of piezoelectric stress sensors, high reliability, can work in the operating temperature range of -20 °C ~ +250 °C. There are analog standard signal and digital pulse signal output. It is easy to use with digital systems such as computers. It is an advanced and ideal flow meter. MST Packaging Co., Ltd. , https://www.mstpack.com
Vortex flowmeter measurement error causes:
1) Insufficient length of straight pipe
2) Analog converter circuit zero drift or full scale adjustment is wrong
3) The supply voltage changes too much
4) Meter exceeds verification period
5) The difference between the inner diameter of the sensor and the pipe is larger
6) Install different hearts or gaskets into the tube
7) Sensor contamination or damage
8) There are two-phase flow or pulse flow
9) Pipeline leak
Vortex flowmeter measurement error solution:
1) Lengthen vortex flowmeter straight pipe section or install flow regulator
2) Calibration zero and span scale
3) Check the power
4) timely inspection
5) Check the inner diameter of the pipe and correct the meter factor
6) Adjust the installation, trim the gasket
7) Cleaning and replacement sensor
8) Exclude two-phase or pulsatile flow
9) Exclude leaks
