Vortex flow meter measurement error causes and solutions!

Abstract: Causes and solutions of measurement errors of vortex flowmeters! The information is provided to you by the excellent manufacturers of flowmeters and flowmeters. Mainly used for flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large measuring range and high precision, and is almost independent of fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the reasons and solutions for the measurement errors of vortex flowmeters! Article details. Mainly used for flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large measuring range, high precision, and is almost not affected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring the volume flow of the working condition. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable for a long time. It adopts piezoelectric stress sensor, which has high reliability and can work in the working temperature range of -20℃～+250℃. There are analog standard signals and digital pulse signal outputs, which are easy to use with digital systems such as computers. It is a relatively advanced and ideal flow meter. The reasons for the large measurement error of the vortex flowmeter: 1) The length of the straight pipe section is insufficient 2) The analog conversion circuit has zero drift or the full scale adjustment is not correct 3) The power supply voltage changes too much 4) The meter exceeds the verification period 5) The inner diameter of the sensor and the pipe is greatly different 6) The installation is not concentric or the gasket protrudes into the pipe 7) The sensor is stained or damaged 8) There is two-phase flow or pulsating flow 9) The solution to the measurement error of the vortex flowmeter for pipeline leakage: 1) Lengthen the straight pipe section of the vortex flowmeter or Install a flow regulator 2) Correct the zero point and span scale 3) Check the power supply 4) Send it for inspection in time 5) Check the inner diameter of the piping, correct the instrument coefficient 6) Adjust the installation, trim the gasket 7) Clean and replace the sensor 8) Eliminate the two-phase flow or Pulsating flow 9) Elimination of leakage The above is the whole content of this article.
