Remote control system for hydraulic pumps monitoring water level - uses inductive magnetic detectors whose field is interrupted according to level of liq.

摘要

The system is designed for the remote control and measurement of liquid level with precision and without the necessity of access to the liquid. The system transforms dynamic information (level reached by a float) into one or several electrical signals. These signals contain all the data necessary for measurement, alarm, recording signalling, and actuation of the pumps controlling the liquid level. The information transformation is obtained by one or several magnetic detectors. The field of these inductive detectors is interrupted when the detectors are in proximity to one or different levels reached by the liquid.
