Pneumatic Liquid Level Monitor Systems

Pneumatic liquid level monitorsNew design electronics provide high reliability and long life with zero current draw except for the short periods required for level checking.

Hookup consists of simply connecting 12 VDC power and the two-wire senders.

Senders are simple, solidly constructed units with no moving parts, thus no floats to stick.
