RDLM-02-EP Electro-Pneumatic Type Level Gauge



The operating principle is basically same as the level measurement of air purge type tank level monitoring system. Therefore Electro-pneumatic type tank level gauging system has electric Indicator and P/I Converts that converts pneumatic input signal to 4~20mA output signal.

The device is used to monitor liquid level for oilcan, pagoda, slot production platform, or ballast tank of shipyard. Also, be used to monitor draft, balance of vertically and horizontally or centralized monitor.
