Our basic system uses a bright LED display, small in
cab mountable enclosure for use on body mounted
tanks. |
 |
|
|
|
|
Provides an accurate digital readout of the amount
of product in a truck tank. |
 |
The Model 808PSi provides a compact, easy to read LED
display ideal for mounting in the close confines of
today’s truck cabs.
|
|
Has a programmable alarm point for operating a SpillStop
overfill prevention system, and a programmable alarm
output which can operate a light, horn, isolation
valve, or the MultiRack
optic/thermistor rack controller.
|
|
The display can be calibrated with the 916 programmer
to read in inches of level, or in volume units such as
barrels, gallons, litres, or cubic metres.
|
|
No moving parts except for the molded plastic float
ensures high reliability.
|
|
SeeLeveL sender bar uses micro power circuitry running
on internal batteries.
|
|
Display operates on 12 volt truck power.
|
|
Built in overfill warning alarm can activate a horn or
light.
|
|
Fibre optic connection between tank and display for
complete electrical safety.
|
|
All digital design eliminates reading drift or
degradation, ensuring long term accuracy under all
operating conditions.
|
|
Operation from -40 to +60 oC (-40 to +140 oF) ambient,
up to +85 oC (+185 oF) product.
|
|
Accuracy of +/- 0.25 inches (+/- 0.7 cm).
|
|
Easy installation and servicing, one year limited
warranty.

The gauge operates using a magnetic reed switch sensor
bar detecting the float magnetic field. The system
provides a nominal accuracy of +/- 1/12 inch, but with
variations in reed switch sensitivities the actual
accuracy is +/- 1/8 inch.
|
|
When the float is rising, the gauge will read about
1/16 inch lower than when the float is falling. This
happens because the reed switches are less sensitive
to engagement than they are to disengagement. The
practical result of this is that the gauge reading is
very stable and does not flicker with small ripples on
the surface of the product.

|
A 316 stainless steel tube houses the sensor bar, and
the fitting holding the tube in place can be either
steel or stainless steel. The tube and polyethylene
float are resistant to oils, fuels, acids, sewage, and
most chemicals. The sensor bar is fully sealed to
prevent moisture or product from damaging the bar. The
bar can be ordered to fit any size tank up to 85
inches in height, and can be easily removed for
servicing, or to install into another trailer.
|
|
The sender bar is powered by a lithium battery with a
lifetime of approximately 10 years.
|
|
Plastic fibre optic cable transports the information
from the sensor bar to the display to provide complete
electrical isolation for the components inside the
tank. The fibre optic light level is ten times higher
than required, so the fibre can be cut with a knife
for easy installation; no polishing or special
preparation is required.
|
|
The 808PSi display is powered by a 12 volt truck
power. The LED display is large enough to allow
viewing from up to 10 feet away. The display is built
into a small plastic enclosure for easy mounting in
the close confines of today’s truck cabs.
|
|
The gauge calibration is programmed during
installation with the 916 programmer. The calibration
can be done in inches of level, or in any volume unit
desired, as long as a calibration table (volume vs.
depth) is available for the tank. The display has four
digits, allowing better than 1/2 % accuracy on the
readout.
|
|
The SpillStop and alarm outputs on the 808PSi are
programmed with the 916 programmer during
installation, and can be altered at a later date if
desired. An overfill warning feature permits a
simple alarm to be operated and then bypassed by
pressing a switch on the outside of the display
enclosure. The alarm will automatically reset when the
tank is empty.
|
|
The SeeLeveL gauge can be used with other Garnet
products to improve safety, economy, and convenience.
The SpillStop overfill prevention system provides an
automatic horn warning and pump shut down to prevent
spills when loading with truck mounted PTO driven
pumps. The MultiRack rack controller provides
optic and thermistor loading rack control to permit
loading at rack controlled facilities.
|
|
The 808 series is one of our most popular models with
nearly 2,000 systems installed to date.
