The FMG800 Series is a full-bore,plastic-bodied electromagneticflow meter designed for flow andusage monitoring applications in1, 2 and 3 inch pipe. Thepolypropylene flow tube offerscorrosion resistance to a widerange of chemicals and fertilizers.It is light weight and easy toinstall or remove from the pipefor inspection*.

With no moving parts, the magmeterpermits unobstructed flow, minimizingflow disturbances and straight piperequirements. The FMG800 Seriescan be used in piping configurationswhere there is little space betweenthe meter and an elbow or valve.The FMG800 Series is resistant towear from sand and debris found inground or surface water. Since thereare no bearings or propeller to wearout, maintenance and repair costsare kept to a minimum and ittolerates high flows without damage.A hinged polyethylene cover isincluded that protects from dust andUV rays, while permitting easyaccess to the flow rate and totaldisplay. Flow rate and total can bedisplayed in a variety of units, but must be factory programmed.

The FMG800 Series is used fortracking flow rate and total flow inusage monitoring applicationsincluding wells, industrial wastewater,heap leach mining discharge, coolingtower deduct, turf, landscape,and other water reclamationapplications. In the event of DC powerloss, or when changingbatteries, the FMG800 will retaininternal settings and flow total.

FMG800 SeriesThe FMG810 Series is externallypowered via a 5-pin connector cablewhich also provides pulse output foruse with a variety of trodeks displaysand controls for remote reading, datalogging, pulse-to-analogconversion, and telemetryapplications.

The FMG800 Series is a battery-operatedunit for use when pulse outputis not required. The batteries are userreplaceable with anapproximate 1 to 2 year lifedepending on usage.
