liquid level measurement. SUBSTANCE: level gauge has several level detectors positioned vertically, switch, converter and two control devices. Parallel-connected diode and extension cable short-circuited at other end are connected at lower end of every level detector. Choke and two capacitors are connected at upper end of every level detector. One of capacitors is connected to converter, while the other, to switch input. EFFECT: enhanced accuracy of measurement. 1 dwg
