Vortex flowmeter output signal is not stable how to do?

Project Overview

Vortex flow meters are commonly used to measure steam, liquid, gas and other media, and are a commonly used instrument type in industrial trade settlement. So how to solve the problem when the output signal of the vortex flowmeter is unstable during use? This article mainly explains the influencing factors and solutions.

Influencing factors

• There is a strong electrical interference signal

• The sensor is contaminated or damp, and the sensitivity is reduced

• The sensor sensitivity is too high

• The sensor is damaged or the lead contact is poor

• The occurrence of two-phase flow or pulsating flow

• The impact of pipeline vibration

• The process flow is unstable

• The sensor installation is not concentric or the sealing gasket protrudes into the pipe

• Upstream and downstream valve disturbance

• The fluid does not fill the pipe

• There are entanglements in the generator

• Cavitation exists

• Solution

• Strengthen shielding and grounding

• Clean or replace the sensor and increase the amplifier gain

• Reduce gain and increase trigger level

• Check sensors and leads

• Strengthen process management and eliminate two Phase flow or pulsating flow phenomenon

• Take shock absorption measures

• Adjust the installation position

• Check the installation condition and correct the inner diameter of the gasket

• Lengthen the straight pipe section or install a flow regulator

• Replace the location and method of installing the flow sensor

• Eliminate entanglements

• Reduce the flow rate and increase the pressure in the pipe

  

  The above are the influencing factors and solutions to the unstable output signal of the vortex flowmeter. If you encounter related problems, please do not disassemble the flow meter without permission to prevent irreversible losses.
