The radar guided wave level gauge has been inaccurate recently
Thread Content
The radar guided-wave level gauge has been giving inaccurate readings recently; the difference between its readings and those of the local level gauge is around 20%. The instrument technicians say there is a problem with the probe. Please share your thoughts on this matter @Thank you
When you ask questions like this, no one knows how to answer you at all.
Reply to 2# olala-1: Impurities in the medium being measured can attach to the probe, affecting the measurement values. Are there any other issues?
Please specify the medium under specific operating conditions, the installation method, the duration of use, and whether there are any special circumstances at the measurement points. Thank you!
You need to specify the medium being measured, whether it is a solid, dust, or liquid (with details such as viscosity), so that it’s possible to determine the cause
If there are impurities and the viscosity is high, then remove the guided wave radar and clean the guided wave rod.
Is it a fixed 20% difference? Is there medium foam?
The probe should be able to be removed for testing
Just listen to what the crew on site says; don’t doubt them. If conditions permit, they will do their best to handle it
