Is the float level gauge showing abnormal levels due to interference from a walkie-talkie?
Thread Content
During the routine inspections carried out by our field operators, they checked the liquid level with the main operator; every time they communicated via the float level gauge, the liquid level fluctuated greatly, and this was promptly noticed by the attentive main operator Why does this cause fluctuations in the liquid level? Has anyone encountered this problem?
We have encountered this problem as well; we are paying attention to it
The instruments have poor resistance to interference; I encountered this issue fifteen years ago, and since then, by paying attention to the right model selection for these instruments, I’ve hardly run into such problems anymore
I see, haha. So which model should be chosen?

It will have an impact on weak electrical signals. Float level gauges contain measuring coils, and if they are not shielded, the transmission signals from walkie-talkies can interfere with them. It seems that the DLC3000 models with FISHER headers are less affected by interference at present. Additionally, some vibration probes from BENTLY are also affected by intercom interference. Therefore, in addition to paying attention to gauge selection and signal shielding, it is recommended to stay as far away as possible from the measuring instruments when using walkie-talkies. Newbie, feel free to give feedback.
