INTRODUCTION
Overview
The FRC TankVisionPro 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 TankVisionPro 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 TankVisionPro indicator is a unique design made up of an extended wide view
lens with 9 or 10 super bright LEDs (depending on the chosen conguration) 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
water or foam concentrate is left in the tank in fractional 1/8 tank eight level increments.
The remote light driver provides the option to have four 60 watt remote lights
controlled by the TankVisionPro to show full, 3/4, 1/2, and 1/4 tank.

GENERAL DESCRIPTION
Components
The TankVisionPro 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 as a fractional amount on the overlay (or available as
a percentage value for a 10 LED display). Outputs from the primary display module
provide tank volume information to other displays and remote devices.
WLA400 Series primary displays are used for Auto Tank ATA400 systems.
WLA300 Series primary displays can be programmed to use pin #5 for Auto Tank
ATA400 systems.
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 adjusts
brightness for day or night operations. The LEDs are programmable for various display
modes and multiple brightness levels:
Note: The MaxVision LED tank display shows how much water or foam
concentrate is left in the tank in fractional 1/8 tank eight level 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 TankVisionPro WLA300 primary display is used to control
an Auto Tank ATA400 system, pin 5 does not provide a ground for the
buzzer. WLA400 Series primary displays are used for Auto Tank ATA400
systems. WLA300 Series primary displays can be programmed to use pin
#5 for Auto Tank ATA400 systems.

INSTALLATION
The TankVisionPro 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 1: It is recommended to mount the display at eye level.
Note 2: Do not use Loctite on any screws near the Lexan lens. Lexan lenses
can become brittle and prone to cracking when exposed to Loctite compounds.
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
#10 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.)
