Float-type level gauges experience large fluctuations
Thread Content
Occasionally, the level fluctuates greatly with the float type; it has been determined that the issue lies with the float. How should this be resolved?
Old fluctuations are usually caused by problems with the angle sensor or the circuit board; of course, it’s also possible that the torsion bar is stuck – try replacing it.
If there are still fluctuations even after turning the valve off, it’s a problem with the instrument; replacing the float transmitter will resolve it
