Vortex flowmeter in the process of use will often appear fluid does not flow, flow display is not zero, or the display value is unstable, the general emergence of these problems, there may be the following reasons, let's take a look at and Shunda flowmeter manufacturers technology Xiaobian analysis:
1. The transmission line shield is poorly grounded. External interference signals are mixed into the input of the display.
2. The pipeline vibrates, and the impeller shakes with it, causing an error signal
3. The closing valve is not closed due to leakage, in fact the instrument shows the amount of leakage
4. Interference between internal circuit boards or electronic components of the display device
Solution
1. Check the shielding layer, and the display terminal is well grounded
2. Reinforce the pipeline, or install brackets before and after the sensor to prevent vibration
3. Check or replace the valve
4. Take "short-circuit method" or item-by-item inspection to determine the source of interference and identify the point of failure
The above is about the reason analysis and solution of vortex flowmeter non-return to zero. If you have any other questions or needs about the flowmeter, you can contact the Shunda flowmeter manufacturer. We will serve you wholeheartedly.
