DEVICE FOR INDICATING CRITICAL LIQUID LEVEL Russian patent published in 1994 - IPC

Abstract RU 2010498 C1

FIELD: agricultural engineering. SUBSTANCE: signals from generator of bipolar pulses enter the key element and the unit for discrimination of low-frequency signal together with potential from sensor to be installed in tank with monitored liquid level. If said potential is other than zero, the key element turns on light and audio signals indicating a critical level of monitored liquid. EFFECT: improved design. 3 cl, 2 dwg
