ABSTRACT:
A robust electronic liquid level gauge apparatus, particularly suitable for use with boiler drum water column, comprises simple probe sensors in the water column, differential amplifier sensors, detectors responsive only to the simultaneous presence of a minimum level signal and a certain frequency, and logic circuits continuously processing outputs from four detectors: its associated probe detector, the one below, and the two above.
