The silo pump level gauge is constantly giving high readings
Thread Content
May I ask the senior brothers and sisters. Why is the level gauge of the silo pump showing a high reading? Please give me some advice.
I’m not sure what exclusion steps you have already taken, nor what your gauge model, installation method, or operating environment are, so I can only offer some general advice: First, work together with the technical team to determine whether the high liquid level readings are accurate； If not, it can be concluded that it is a false alarm from the instrument itself ； Reconfirm the false alarm situation: whether it was caused by a fault in a primary component or a secondary component ； Among these, primary component failures such as blockages in pressure transfer tubes, deformation of pressure sensing diaphragms, stuck float balls, and contamination of radar wave receiving components are identified step by step depending on the type of instrument ； Secondary component failures such as transmitters or contact switches (normally open/normally closed), cables, as well as settings in the signal input systems (DCS/PLC, etc.), such as the setpoints for alarm values; there may also be issues with the 4-20mA signal not being released properly during loop tests, etc. There are too many reasons, too little information, and an overwhelming variety of level gauges – so it can only be investigated step by step.
It’s not a level gauge; it’s a material level gauge, I guess. The probe is probably covered with material
What was said on the 3rd floor is absolutely correct; it’s necessary to systematically investigate different fault conditions for various types of watches.
On the one hand, when estimating, there may be adhesive on the switch, the contacts might get stuck, or it’s possible that the open and closed positions are reversed.
