OVERVIEW

The AUTO TANK System is designed to work with around-the-pump foam systems where there is a
need to fill the water tank and maintain low pressure at the pump intake while pumping foam.

Normal operations would require pressurized water from a hydrant or pumper in relay to be connected
to the input of the pump. During foam operations excessive pressure at the input side of the pump can
cause the foam system to operate at partial capacity or fail to inject foam. This limits foam system
operations to the amount of water in the tank. When pressurized supply water flow is controlled the
AUTO TANK system, the water volume in the tank of a pumper is automatically maintained. Low
pressure water is available at the input side of the pump continuously to extend foam system
operational capabilities

Features

 Maintains tank water volume between 50% and 95% full (P/N 08899155), or between 75% and

100% full (P/N 08899156)

 Controls water flow for any GPM rate
 For use with tanks over a 500 capacity
 Self-Calibrating for any shape or size tank
 Automatic or manual control

Components

 TankVision Display Module
 AUTO TANK Control Module
 Pressure Sensor
 Elkhart E3F Unibody Control Valve (Sold Separately)
 All necessary component harnesses

TankVision Display Module
The tank volume display module is waterproof and has dimensions of 4.4 inches high by 3 inches

wide. An output signal from a pressure sensor mounted on the tank is input to the display module. It is
processed and the volume of liquid in the tank is shown on the 9 LED display. An output from the
display module controls the opening and closing of the control valve when the automatic mode is
selected.

AUTO TANK Control Module
The control module provides an interface between the TankVision display module and the valve. It has

four push buttons that allow the operator to select the mode of operation. The control module also has
automatic tank fill and manual valve control indicators. The open and close LEDs provide valve
position feedback.

The controller for P/N 08899155 stays in manual or automatic mode until changed. The controller for
P/N 08899156 powers up in automatic mode even if it was in manual mode when powered down.

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.
