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 flow rate
of 60 GPM. If the flow 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.
