INSTALLATION, CONNECTIONS, and Operation

INSTALLATION

Mounting. The FMG210/220/230 can be supported by its piping connections if the piping is rigid and there is no vibration. Alternatively, the grounding studs can be used for mounting by inserting them through pre-drilled holes. Note the centerline distance in the dimensional drawing on following page.

CAUTION: Although this meter has an empty pipe detection function, under certain conditions of empty or partially-full pipe the meter may read a flow when there is none. If this is a

hazardous condition, mount the meter in such a way as to ensure the meter will always be full of liquid.

Piping. Metallic pipe or tube, or plastic tubing, can be used with the meter. The meter comes with male NPT or barb fittings (see chart, next page, for sizes).

For plastic tubing, use female NPT tubing adaptors. In installations exposed to vibration, it is not recommended to use the piping as the sole support for the meter, particularly on the smaller sizes.

A minimum of 1” of straight pipe run is recommended on the inlet side of the meter. Straight run is not necessary on the outlet.

Connections

Power and signal connections are provided by the single 4- or 6-conductor color-coded cable. See the Wiring Connections chart on next page. In addition, it is necessary for proper operation to ground the unit to a good quality earth ground. Use the 12 ft. grounding wire supplied with the unit, or if necessary, a longer wire attached to one or both of the grounding studs. If metal piping is used, ground connections from the grounding studs on the bottom of the unit to both inlet and outlet pipes provide the best results in metering accuracy. See Grounding diagrams.

OPERATION

The newly-installed meter takes from a few seconds to a minute for the signal to stabilize at startup, especially if it has been dry. In normal operation, keep the meter filled with fluid to prevent this delay. An empty pipe detection feature will normally detect absence of liquid in the pipe and register zero flow when the meter is mounted properly.

The 4-20 mA signal outputs 4 mA at zero flow and 20 mA at maximum rated flow. The standard pulse signal is a 50% duty cycle pulse set at 1000 pulses/liter (3785 pulses/gallon).

FMG210, FGM220, FMG230 specifications

Omega Engineering is a leading provider of measurement and control solutions, and its FMG series of mass flow meters, including the FMG230, FGM220, and FMG210, exemplifies the company's commitment to accuracy and reliability in flow measurement.
