Insight into Low Flow Sensor Anomaly

Note from [email protected]: “The level sensor itself is a platinum wire. The wet/dry situation is a measure of resistance. After the tank was drained, one sensor showed wet but 3 hours later showed dry. In a later test the sensor again disagreed with the others but 5 minutes later agreed. Current thinking is that the vast time difference in the reading returning to nominal indicates that this is a mechanical problem where vibration (wind gusts, etc.) that can produce instant effects would be causal, rather than electrical where environmental (temperature, humidity) changes that are slow to build and slow to dissipate would be the culprit.”
