Omega’s new plastic body, corrosion resistant FMG800 series is a full-bore electromagnetic flowmeter that features a built-in rate and total indicator. With no moving parts, the magmeter permits unobstructed flow, minimizing flow disturbances and straight pipe requirements. The flowmeter is designed 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.

The FMG800 Series is available in 1-, 2-, and 3-in. pipe sizes. 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 for inspection. 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. Flow rate and total can be displayed in a variety of units, but must be factory programmed. In the event of power loss or when changing batteries, the unit will retain internal settings and flow total. A five-pin connector cable carries power and also provides pulse output for use with a variety displays and controls for remote reading, data logging, pulse-to-analog conversion, and telemetry applications. If the pulse output is not needed, the unit can run on batteries with a typical lifespan of one to two years.

Accuracy is ±1% of reading between 10% and 100% of max flow. Minimum/maximum flow rate:

1 in.: 2.3 to 110 gpm (0.145 to 6.94 lps)
2 in.: 6 to 300 gpm (0.38 to 18.9 lps)
3 in.: 14 to 670 gpm (0.88 to 42.3 lps)
