Overview
Fluid Level Sensors
The fluid level sensors detect the tank fluid level and
signals the Fluid Defender to activate the alarm and
deactivate the air control solenoid valve (if configured
on the specific channel).
Control level sensor: A level sensor connected as a
control level sensor to the Fluid Defender that controls
the output of an air control solenoid valve. Either a high
level or low level sensor may be connected as a control
level sensor
Monitor level sensor: A level sensor connected to the
Fluid Defender as a monitor level sensor that monitors a
tank fluid level. Either a high level or a low level sensor
may be connected as a monitor level sensor.
NOTE: Level sensors are preconfigured at the factory.
Do not attempt to reconfigure a level sensor by
changing the float orientation. High level sensors are
unable to be configured into low level sensors, and low
level sensors are unable to be configured into high level
sensors.
High Level Sensors
A sensor that is used to detect a full tank. The float is in
the down position and the sensor contacts are closed
during normal operation (F
The float moves to the up position and the sensor
contacts are open during a high level condition,
triggering the Fluid Defender alarm (F
illustration b).
Low Level Sensors
A sensor that is used to detect an empty tank. The float
is in the up position and the sensor contacts are closed
during normal operation (F
The float moves to the down position and the sensor
contacts are open during a low level condition,
triggering the Fluid Defender alarm (F
illustration d).
