The FMG800 Series is a full-bore,
flow meter designed for flow and
usage monitoring applications in
1, 2 and 3 inch pipe. The
polypropylene flow tube offers
corrosion resistance to a wide
range of chemicals and fertilizers.
It is light weight and easy to
install or remove from the pipe
With no moving parts, the magmeter
permits unobstructed flow, minimizing
flow disturbances and straight pipe
requirements. The FMG800 Series
can be used in piping configurations
where there is little space between
the meter and an elbow or valve.
The FMG800 Series is resistant to
wear from sand and debris found in
ground or surface water. Since there
are no bearings or propeller to wear
out, maintenance and repair costs
are kept to a minimum and it
tolerates high flows without damage.
A hinged polyethylene cover is
included that protects from dust and
UV rays, while permitting easy
access to the flow rate and total
display. Flow rate and total can be
displayed in a variety of units, but
must be factory programmed.
The FMG800 Series is used for
tracking flow rate and total flow in
usage monitoring applications
including wells, industrial wastewater,
heap leach mining discharge, cooling
tower deduct, turf, landscape,
and other water reclamation
applications. In the event of DC power
loss, or when changing
batteries, the FMG800 will retain
internal settings and flow total.
The FMG810 Series is externally
powered via a 5-pin connector cable
which also provides pulse output for
use with a variety of Omega displays
and controls for remote reading, data
conversion, and telemetry
The FMG800 Series is a battery-operated
unit for use when pulse output
is not required. The batteries are user
replaceable with an
approximate 1 to 2 year life
depending on usage.
*Includes Omega NPT fitting kit on
2 and 3" models.
