This panel is used for control of liquid level over the deadband of the pneumatic float valve (approximately 1/4" to 1/2"). The control panel pilots a fill or drain valve that operates a pump. A normally open float valve is used. The output control is "on" (indicator red) when the level is low and is "off" when the level is high (indicator green).

Includes inlet filter, regulator and gage assembly.

The output signal can also be used as a remote indicator signal to operate a visual indicator or a sonic alarm. Use as follows:

Low Level Alarm – use a normally open float valve

High Level Alarm – use a normally closed float valve
