Liquid level indicator based on a float system, has a sensor arrangement that detects movement of a float tube within a guide and triggers two signals according to two different fluid levels

摘要

The liquid level indicator has a float (15) with a sensor for giving out a level dependent signal and a float tube signaler (14). The float tube interacts with the sensor dependent on the position of the float. Float tube signaler and sensor interact in such a manner that when the float reaches one level a first signal is generated, while when it reaches a second level a second signal is generated.
