Pressure Sensor
The pressure sensor is mounted on a side of the tank near the bottom. It provides a signal that is
proportional to the volume of liquid in the tank to the input of the primary display module. The
electrical connector is waterproof and molded into the pressure sensor housing.
The pressure sensor is used on tanks between 1 and 10 feet in vertical height.
Control Valve
The E3F electric actuator is utilized for control of the tank fill valve. The AUTO TANK control module
communicates to the E3F electric actuator via the J1939 data bus. It can be mounted on any standard
sized Unibody valve.
NOTE: An Elkhart control valve is not included with the AUTO TANK Fill System, and must be
purchased separately.
