Liquid-Only Float Sensor
OPW P/N: 30-0230-S
Liquid-only Float Switch
Designed to detect the presence of fluid in the interstitial space of a
steel double-walled tank or a containment sump. The sensor, which
utilizes float technology, activates on the presence of water or fuel
and provides an alarm condition. An alarm condition will also occur if
the cable is broken.
Liquid-Only Float Sensor Installation
1. Check that the sump is dry.
2. Position the sensor approximately ½-inches (1.3 cm)
above the bottom of the sump/pan and secure sensor
wire to an existing pipe or bracket with a tie wrap.
3. Connect the sensor wires to the field wires in the junction
box using the supplied wire nuts.
4. Seal the electrical connections with the epoxy seal
packs.
