Summary

The operating principle is basically same as the level measurement of air purge type tank level monitoring system. Therefore Electric-penumatic type tank level gauging systemhas electric Indicatorand 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 ofshipyard. Also, be used to monitor draft, balance of vertically and horizontally or centralized monitor.
