INTRODUCTION
Overview
The FRC TankVision indicator shows the actual volume of liquid in a tank. The
liquid in the tank exerts a pressure that is measured by a sensor. As the amount of
liquid changes, the pressure it exerts on the sensor changes proportionally. The pressure
change is used to calculate the exact volume of liquid in the tank. The TankVision can
be calibration to accurately display the volume of liquid in tanks of all shapes and sizes.
The display module is able to communicate with other display modules over the
FRC datalink. This allows for one master display module to control multiple displays.
The module also provides an output for cab miniature displays, remote light drivers,
and a low level warning buzzer.
The TankVision indicator is a unique design made up of an extended wide view
lens with nine super bright LEDs mounted behind it. This allows the display to be
visible and clearly read from all line-of-sight angles for a full 180 degrees.
The pressure/vacuum foam tank vent is supplied for use on foam concentrate storage
tanks. These tanks should remain closed to the atmosphere. The FRC vent enables
the tank to compensate for changes in pressure or vacuum due to thermal expansion,
lling, or when withdrawing foam concentrate from the tank.
The MaxVision LED tank display provides a remote, wide angle view of how
much is in the tank in 1/8 tank level increments.
The remote light driver provides the option to have four 60 watt remote lights
controlled by the TankVision to show full, 3/4, 1/2, and 1/4 tank.

GENERAL DESCRIPTION
Components
The TankVision consists of the following components:
Display Module
Cab Miniature Display (Optional)
Pressure Sensor
Pressure/Vacuum Relief Vent (Foam Tanks)
MaxVision LED Tank Display (Optional)
Remote Light Driver (Optional)
Buzzer (Optional)
Cables
Display Module
The tank 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 primary display module. It is processed and the volume of liquid in the tank is
shown on the 9 LED display. Outputs from the primary display module provide tank
volume information to other displays and remote devices.
Non-standard primary displays are used for Foam Fill FFA100 and Auto Tank
ATA400 systems. These require special programs for the correct controlling output
on display connector pin 5.
Cab Miniature Display (Optional)
The cab miniature display has dimensions of 2.75 inches high by 1.5 inches wide.
It provides the option of mounting a remote display in the cab that uses a minimum
of panel space. An output signal from the primary display module is input to the cab
miniature display and the volume of liquid in the tank is shown on the 5-LED display.
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 standard pressure sensor is used on tanks between 1 and 10 feet in vertical
height. For tanks taller than 10 feet contact FRC for options.

Pressure/Vacuum Foam Tank Vent
The pressure/vacuum foam tank vent is supplied for use on sealed foam tanks.
The vent compensates for changes in tank pressure due to thermal expansion or when
withdrawing foam concentrate from the tank. Internal passageways provide a path
for air to move between the tank and a center cavity in the vent. These passageways
are self-draining and designed to prevent splashing foam from entering the center
cavity and clogging the pressure and vacuum valves. The pressure and vacuum valves
are easily accessed and disassembled for periodic cleaning or inspections. (Refer to
Maintenance section.)
Note: The vent can compensate for a maximum foam concentrate ow rate
of 60 GPM. If the ow rate of foam concentrate from the tank will exceed
60 GPM, two (2) vents will be required.
MaxVision LED Tank Display (Optional)
The LED display is waterproof and has dimensions of 14 3/8 inches high by 1 7/8
inches wide by 7/8 inch deep. It has 96 RGB LEDs and built in LED drivers. A signal
from the primary display module is output on a two wire datalink and input to the LED
light to show the volume of liquid in the tank.
The display shows the level in 1/8 tank increments. It has a photo sensor that adjust
brightness for day or night operations. The LEDs are programmable for two modes of
display and ten brightness levels:
Ultra - All LEDs are one color and change at each 1/4 tank increment.
Typical - LEDs show four colors for 1/4 tank increments.
Remote Light Driver (Optional)
The remote light driver is waterproof and has dimensions of 4 inches high by 2.75
inches wide by 1 inch deep. An output signal from the primary display module is input
to the remote light driver. This provides the option to power four (4) 60 watt remote
lights that show the volume of liquid in the tank. The lights will show full, 3/4, 1/2,
and 1/4 tank levels.
Buzzer (Optional)
The buzzer provides an audio alarm when the tank volume drops to 25%. The
buzzer resets when the tank volume goes above 25%.
Note: When the TankVision primary is used to control a Foam Fill FFA100
or Auto Tank ATA400 system, pin 5 does not provide a ground for the
buzzer. The primary display is programmed from the factory with a control
output on display connector pin 5 for each of these special systems. These
displays are not interchangeable.

INSTALLATION
The TankVision primary display module is connected to the pressure sensor and
is the only module that needs to be calibrated.
Note: The calibration procedure needs to be performed every time a primary
display module is installed.
Install Display Module
The full size display modules all have the same mounting dimensions. Standard
display modules are interchangeable.
Note: It is recommended to mount the display at eye level.
1. Measure and mark mounting location for display module panel cutout and
mounting screw holes. Make sure there is clearance behind the panel for
the display and cables before cutting holes. Refer to Figure 1 for layout and
dimensions.
2. Cut out a 4 by 2 1/8-inch hole and drill four (4) holes (clearance or tapped) for
6-32 mounting screws.
3. Place display module in position and secure with four (4) screws.
4. Connect the display module cables and wires. (Refer to Wiring Section.)
Install Cab Miniature Display
1. Measure and mark mounting location for cab miniature display mounting hole.
Make sure there is clearance behind the panel before drilling hole. Refer to
Figure 2 for layout and dimensions.
2. Drill a clearance hole for 3/8" threads.
3. Place cab miniature display in position and secure with nut.
4. Connect the cab miniature display wires. (Refer to Wiring Section.)

Install Pressure Sensor
The pressure sensor is mounted on one of the tank sides approximately 2 inches
from the bottom. If the tank has a vertical height greater than 10 feet contact FRC, a
different sensor may be required.
Pressure sensors are interchangeable. It is recommended that the calibration
procedure be performed if the pressure sensor is changed.
Note: When mounting the pressure sensor on a tank with thin walls, less
than 3/8", it is recommended that the tank wall be reinforced at the sensor
mounting location.
Pressure Sensor Installation
Note: Do not mount the sensor in the bottom of the tank. Sediment may collect in the
port and cause sensor failure.
1. Measure and mark mounting location for sensor. (Mounting hole should be
approximately 2" from bottom of tank.) Make sure there is clearance for sensor
and cable before drilling hole. Refer to Figure 3 for dimensions.
2. Drill and tap a 1/4 NPT hole.
3. Apply sealant around base and threads of pressure sensor.
4. Screw sensor into hole.
5. Connect sensor cable. (Refer to Wiring Section.)
Thin Wall Adapter Installation
The thin wall adapter kit includes the adapter, two 10-24 x 5/8" screws, 5 minute
epoxy, and a mixing stick.
1. Measure and mark mounting location for adapter. Make sure there is clearance
for adapter, sensor, and cable before drilling hole. Refer to Figure 3 for
dimensions.
2. Drill and tap a 1/2 NPS hole.
3. Screw the adapter into the hole.
4. Use the adapter as a template and drill and tap two 10-24 holes for two screws.
5. Back adapter out of hole and apply 5 minute epoxy to back of ange, on threads,
and in two 10-32 through holes.
6. Screw adapter into hole and secure with two screws.
7. Allow the epoxy time to set.
8. Apply sealant around base and threads of pressure sensor and screw into adapter.
9. Connect sensor cable. (Refer to Wiring Section.)
