Live Transformers Presentation (Paul) | Valve | Transformer level sensor is a pressure sensor that will operate on transformers that are up to 20m high. The absolute sensor output is not critical, the concern is only for changes to the reading. It is important to allow the sensor reading to stabilise for 30 minutes prior to using the automatic shut-off system.
