INTRODUCTIONOverview

The FRC TANKVISION volume indicator shows the actual volume of liquid ina tank. The liquid in the tank exerts a pressure that is measured by a sensor. As theamount 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. TheTANKVISION can be calibration to accurately display the volume in tanks of allshapes and sizes.

The display module is able to communicate with other display modules over theFRC 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 wideview lens with nine super bright LEDs mounted behind it. This allows the display to bevisible 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 concentratestorage tanks. These tanks should remain closed to the atmosphere. The FRC ventenables the tank to compensate for changes in pressure or vacuum due to thermalexpansion, filling, or when withdrawing foam concentrate from the tank.

The remote light driver provides the option to have four 60 watt remote lightscontrolled by the TANKVISION to show full, 3/4, 1/2, and 1/4 tank.

GENERAL DESCRIPTIONComponents

The TANKVISION volume indicator consists of the following components:

Display Module

Pressure Sensor

Pressure/Vacuum Relief Valve (Foam Tanks)



Buzzer (Optional)

Cables

Display Module

The tank volume display module is waterproof and has dimensions of 4.4 incheshigh by 3 inches wide. An output signal from a pressure sensor mounted on the tank isinput to the master display module. It is processed and the volume of liquid in the tankis shown on the 9 LED display. Outputs from the master display module provide tankvolume information to other displays and remote devices.

Pressure Sensor

The pressure sensor is mounted on a side of the tank near the bottom. It providesan signal that is proportional to the volume of liquid in the tank to the input of themaster display module. The electrical connector is waterproof and molded into thepressure sensor housing.

The pressure sensor FRC part number WL-PT1 is used on tanks between 1 and10 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 will compensate for changes in tank pressure due to thermal expansion orwhen withdrawing foam concentrate from the tank. Internal passageways provide apath for air to move between the tank and a center cavity in the vent. These passagewaysare self-draining and designed to prevent splashing foam from entering the center cavityand clogging the pressure and vacuum valves. The pressure and vacuum valves areeasily accessed and disassembled for periodic cleaning or inspections. (Refer toMaintenance section.)

Note: The vent can compensate for a maximum foam concentrate flow rateof 60 GPM. If the flow rate of foam concentrate from the tank will exceed60 GPM, two (2) vents will be required.

WL2000 Rev0404

The cab miniature display has dimensions of 2.25 inches high by 1 inches wide. Itprovides the option of mounting a remote display in the cab that uses a minimum ofpanel space. An output signal from the master display module is input to the cabminiature display and the volume of liquid in the tank is shown on the 5-LED display.


The remote light driver is waterproof and has dimensions of 4 inches high by 2.75inches wide by 1 inch deep. An output signal from the master display module is inputto the remote light driver. This provides the option to power four (4) 60 watt remotelights that show the volume of liquid in the tank. The lights will show full, 3/4, 1/2, and1/4 tank levels.

Buzzer (Optional)

The buzzer will provide an audio alarm when the tank volume drops to 25%. It willbuzz 9 times. The buzzer resets when the tank volume goes above 25%.

OPERATIONNo operator input is required for the TANKVISION to be operational. When

power is on the tank volume gauge will be operating. The signal from the pressuresensor is processed and the tank volume shows on the display.

Note: Calibrating the TANKVISION display to the tank is required beforeoperations. (Refer to Calibration section.)

Master Display Module

All 9 LEDs will be on when the tank is full.

Each LED will go off starting at the top as the tank volume decreases.

The bottom 2 LEDs will flash when the tank volume is less than 25%.

All 9 LEDs will rapidly down-chase when the tank is almost empty.

Options

Remote Display Module

The remote display will repeat exactly what is shown on the master display.

Cab Miniature Display

All 5 LEDs will be on when the tank is full.

The LEDs will show full, 3/4, 1/2, 1/4, and empty tank.

Remote Light Driver

Note: If there is no signal on pin 2 (input from a display module) the lightswill remain off. (Refer to Wiring section.)

When power is applied the remote light driver will run a lamp test function. Thelamp test will start at the 1/4 light and cycle each remote light on and off. At thecompletion of the lamp test the remote light driver turns on the lights to show the tankvolume.

All 4 lights will be on when the tank is full.

The lights will show full, 3/4, 1/2, and 1/4 tank.

The 1/4 light will blink when the tank volume is less than 25%.

Buzzer

The buzzer will sound when the the tank volume drops to 25%.

CALIBRATIONThe TANKVISION has unique calibration programs that enable it to be used on

tanks of all shapes and sizes.

Note: The standard pressure sensor is limited to a maximum tank height often feet.

Overview

Magnet Sensor

The calibration programs are accessed by activating the CAL. magnet sensor thatis located at the bottom on the front of the display module. The sensor is activated byplacing the north pole of a small magnet in close proximity of the sensor. (The sensorwill not respond to the south pole of the magnet.) The magnet is then moved about 1-inch away, this will produce an electronic signal that is similar to a button being released.If the LEDs in the display do not change try moving the magnet further away from thesensor.

In these procedures the term ‘swipe’ will mean to move the magnet up to and thenaway from the magnetic sensor.

Non-Linear Calibration

The first program is a non-linear calibration procedure that can be used for anyshape or size tank. This procedure must to be used for irregular shape tanks (e.g.: T-shape, oval, elliptical, tank with through hole, etc.). The program compares the pressurein the tank, as the tank fills at a steady rate, to time. This provides accurate volumedisplays.

Linear Calibration

The second program is a linear calibration procedure that can only be used whenthe tank volume is proportional to the height. This would include square or rectangularshape tanks with no irregularities. It is quick way of calibrating a tank but not asaccurate as the non-linear procedure. The program compares a full tank to an emptytank, takes the difference and divides it into eight equal volume displays.

Fine Calibration

This program is for use to fine tune the tank volume display after a non-linear orlinear calibration procedure has been completed. It would only be needed in caseswhere one type of liquid is used for calibration when a different liquid would normallybe in the tank. For example this would allow the basic calibration of a foam tank to bedone using water and then the calibration would be fine tuned when the tank is filledwith foam.

WL2000 Rev0404

17

Non-Linear CalibrationThis non-linear calibration procedure can be used for any shape or size tank. The

calibration process requires that the tank be empty at the start of the procedure andthen filled at a steady rate of flow.

The term ‘swipe’ will mean to move the magnet up to and then away from theCAL. sensor at the bottom of the display.

To exit the calibration mode swipe the magnet eight times. The top eight displayLEDs go on, the calibration program terminates, no program data is changed.

1. Empty the tank.

2. Apply power to the display module.

3. Swipe the magnet three times to enter the calibration mode.

Result: Top three display LEDs flash on and off.

Note: Once the calibration process is activated the flow rate of liquid into thetank must remain constant for the procedure to be accurate.

4. Fill the tank at a steady rate of flow.

5. When the tank is full stop the flow. (There is no problem if the tank overflows.)

Note: The program will only act on three swipes to set the calibration intomemory, or eight swipes to terminate the calibration program. If a wrongentry is made, wait six seconds and it will clear.

6. Swipe the magnet three times to set the calibration into memory.

Result: Top three display LEDs go on.

7. After six seconds the calibration process will terminate and all the LEDs willgo on to show that the tank is full.

WL2000 Rev0404

18

Linear CalibrationThis linear calibration procedure can only be used for square or rectangular shape

tanks with no irregularities. The calibration process requires that the tank be full at thestart of the procedure.



1. Fill the tank.


Note: Once the calibration program is activated there is a six second timeout. Do not wait more than six seconds to move from step 3 to step 4.

3. Swipe the magnet four times to enter the calibration mode.

Result: Top four display LEDs flash on and off.

4. After three seconds swipe the magnet four times to set the calibration intomemory.

Result: Top four display LEDs go on.


WL2000 Rev0404

19

Fine CalibrationThis fine calibration procedure is used to fine tune the tank volume display after a

non-linear or linear calibration has been completed. The calibration process requiresthat the tank be full at the start of the procedure and the display shows 75% or more.



1. Fill the tank.


Note: Once the calibration program is activated there is a six second timeout. Do not wait more than six seconds to move from step 3 to step 4.

3. Swipe the magnet five times to enter the calibration mode.

Result: Top five display LEDs flash on and off.

4. After three seconds swipe the magnet five times to set the calibration intomemory.

Result: Top five display LEDs go on.
