Vortex flowmeter signal output is not stable how to do?

During the use of vortex flow meters, users often encounter problems such as unstable and irregular signal output or unstable instantaneous flow. If you encounter such problems, you can check the following points:

1. First check whether the medium flow rate in the pipeline exceeds the measurable flow range of the sensor;

2. If the medium flow rate is within Within the measurable range, check whether the front and rear straight pipe sections meet the requirements, and confirm whether the medium in the pipeline is in a stable flow state, and there is no two-phase flow or pulsating flow in the pipeline;

3. Check whether the vibration intensity of the pipeline is excessive If it is too large, you can install a pipeline support point 2D downstream of the flow meter; on the premise of meeting the straight pipe requirements, install a hose transition;

4. Check whether there are strong electrical interference signals around the instrument, and if so, strengthen shielding and grounding;

5. Check whether the sensor is contaminated, damp, damaged, or has poor lead contact. , if necessary, please clean or replace the sensor and tighten the lead;

6. Check whether the sensor is installed concentrically or whether the sealing gasket protrudes into the pipe. If there is any installation problem, adjust the inner diameter of the gasket;

8. Check whether the process flow is stable and adjust the installation position;

9. Check whether there is any entanglement on the generator;

10. Check whether there is cavitation in the pipe. If the flow rate is reduced, increase the pressure in the pipe.

If the user's technical personnel cannot solve the related problems, they can consult the vortex flowmeter manufacturer. Supmea Instruments is a professional vortex flowmeter manufacturer.
