Liquid-Only Float Sensor
Part No. 30-0230-S
Designed to detect the presence of fluid in the interstitial space of a steel
double-walled tank or a containment sump. The sensor (Figure 5-6),
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.
*Maximum Wiring Length is the maximum length of cable to be used
to connect all sensors on an individual channel. This length includes
run of cable from VSmart to each sensor board in the string.

2. Position the sensor approximately 1/2” (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.
