GENERAL INFORMATION

The FMG-1000 Series are anged electromagnetic
owmeters for use in 4” to 10” pipe in municipal or industrial
water and wastewater applications where propeller meters
have typically been used in the past. Because the FMG­1000 has no moving parts and has electrodes designed
to discourage fouling, this magmeter performs well and
requires much less frequent maintenance in applications
where debris or sand would impede propeller meters. There
is no rotor to stop turning or bearings to wear out. Minimal
straight pipe requirements allow FMG-1000 Series meters to
be used in piping congurations where there is little space
between the meter and an elbow.

In chemical injection applications, the meter should be placed
upstream of the injection line or far enough downstream for
thorough mixing to occur before the meter.

Rate and total indication are standard on both models. Flow
measurement units are customer-selected and factory-set
and can only be changed in the eld by an authorized Omega
dealer.

The FMG-1000 is externally powered with 7-26 Vdc at 30 mA
max (see WARNING on Wiring Diagrams).

The 20-foot power cable also provides pulse output for use
with a variety of displays and controls for remote reading,
data logging, pulse-to-analog conversion, and telemetry
applications. Pulse rate is customer-selected and factory-set
and can only be changed in the eld by an authorized Omega
dealer. Default is high frequency for use with 4-20 mA signal
conversion devices.
