Flow transmitter
Thread Content
Sometimes, when there is no fluid in the pipeline, the flow meter shows a high flow rate. What is the reason for this? How to solve it?
It’s not specific enough – what kind of transmitter is it?
What type of flow meter, and what is the medium being measured?
Piping vibration? Are there interference signals? Who knows what kind of flow meter you’re talking about?
Is it a throttle differential pressure type? There is usually small-signal rejection
Yes, how to remove small signals?
If it shows a large value, then it’s not a problem of low-flow resection
It requires a specific analysis; the information you’ve provided is too limited
What kind of flow transmitter? Please clarify, OP
Interference and vibration: when the flow rate is below the minimum value, small-signal rejection can be applied.
