ongratulations on purchasing the Garnet Instruments Model
809-DM SEELEVEL SPECIAL™ Gauge for Trucks. The SEELEVEL
represents the state of the art in liquid level measurement
equipment for transport applications. The SEELEVEL is designed
for reliable, accurate level measurement of sour or sweet crude oil,
chemicals, acids, water, condensate, gasoline, or diesel fuel. The
liquid level is determined by sensing the position of a magnetic
oat using a series of reed switches arranged in a vertical sensing
bar. This technology has no moving parts except for the oat, and
can operate over a range of product temperatures from -40°C to
+90°C (-40°F to +194°F).
The 809-DM SEELEVEL has been designed to withstand the vibration
and shock encountered in mobile applications.
The 809-DM SEELEVEL can display in any units, such as inches of
level, pints, quarts, gallons, barrels, or cubic metres of volume. It
has multiple alarm relay and transistor outputs which can be used
to operate horns, lights, pumps, valves, or engines.
The 817 Truck Gauge Programmer is used to program the SEELEVEL
to read the desired calibration units. It is designed to be easily
operated by people unfamiliar with electronics or computers.
The 809-DM is designed specically for trucks with multiple
tanks (up to 6, plus up to 3 water tanks using additional 808P2
gauges) which are used to accurately dispense chemicals. Front
panel controls, remote communications, PTO sensing, and a full
complement of alarm outputs make it a complete solution for this
type of truck. Battery operation of the basic level functions allows
checking of tank levels even with the truck turned off.
