E+H radar level gauge
Thread Content
There is an E+H radar level gauge. During the rise and fall of the liquid level, it always stays fixed at a certain value and doesn’t change. For example, when the level is empty, the reading remains at 5%, without any change; sometimes, when the actual level is 70%, the reading stays at 120% instead. Restoring power to the device can bring it back to normal, but no measures seem to be able to fix this issue. What could be the problem? Occasionally, there are some small bubbles, and the liquid level fluctuates more when liquid is being poured in, but this used to not be a problem before
Has it been used for so long that it’s time to replace it? If it worked fine for a long time before, try using a new watch. It seems that the quality of many level gauges these days isn’t as good as it used to be.
It could be a problem with the response time, but that’s unlikely; since the devices are already in operation, no one would change their parameters. So it’s almost certain that it’s not a parameter-related issue. I’m not sure what material it is – you can check whether there are any clumps of material at the nozzle, and also verify that the wiring of the sensors isn’t loose. The wiring for E+H sensors is made of copper, and over time it may loosen or deteriorate due to temperature effects.
Measure the voltage when it freezes; you suspect it’s too low, which prevents it from functioning
There isn’t enough information to make a judgment; for example, it’s not clear how long it has been in use. It could be that the detection head is no longer functioning properly, or the converter might be faulty, or the parameters may not be set correctly. Based on my experience with Siemens level gauges, it’s likely that the probe needs to be replaced. Another possibility is that the voltage might be too low
