GENERAL INFORMATION
The
FMG490 Series
is a spool-type electromagnetic
flowmeter for use in irrigation applications in 3” to 12” pipe.
With no moving parts, these meters provide unobstructed
flow and are resistant to wear from debris found in ground
or surface water. Little maintenance is required because
there are no bearings to wear out or propellers to stop
turning. Minimal straight pipe requirements allow FMG490
meters to be used in piping configurations where there is
little space between the meter and an elbow.
The display for the FMG490 is mounted remotely for ease of
access. The FMG490 is available as either AC or DC powered,
with battery backup. Both rate and total indication show
on the remote mounted display. Bidirectional flow reading
is standard with totals available in forward, reverse, net
flow, batch forward flow, and batch reverse flow. Batch
totals can be reset. Built-in data logging is available as an
option for secure flow logging.
Scaled pulse output is standard and one additional output
can also be added, such as 4-20mA.
The FMG490 Series is CE certified and IP68 for burial, or
applications where the meter may be under water for
prolonged periods of time. All meters are provided with
a security seal to protect against unauthorized access.
The seal can be broken by an authorized agent to replace
the battery pack or field install a power/output cable. The
cable(s) are field installed.
