Product Description
The WMP-Series are a full-bore, plastic-bodied electromagnetic flowmeters designed for flow and usage monitoring applications in 1 or 2 inch pipes.  The electromagnetic flowmeter's polypropylene flow tube offers corrosion resistance to a wide range of chemicals.  The electromagnetic flowmeters light weight and clamp flanges allow them to be easily installed or removed from the pipe for inspection*.  There are multiple adapters available to allow the electromagnetic flowmeters to fit into a wide variety of pipe mounting configurations.
*Use Banjo® fittings or the WMP Fittings Kit
With no moving parts, the electromagnetic flowmeters permit unobstructed flow, minimizing flow disturbances and hence, straight pipe requirements.  The WMP-Series electromagnetic flowmeters can be used in piping configurations where there is little space between the meter and an elbow or valve.  The WMP-Series, like other electromagnetic flowmeters, are resistant to wear from sand and debris found in ground or surface water.  Since there are no bearings or propeller to wear out on the electromagnetic flowmeters, downtime and maintenance and repair costs are kept to a minimum.  Because the electromagnetic flowmeters have no mechanical parts in the flow stream, the meter tolerates high flows without damage. The electromagnetic flowmeter's hinged, opaque polyethylene cover protects from dust and UV rays, while permitting easy access to the LCD flow rate and total display.  The electromagnetic flowmeter's electronics housing is made of rugged powder-coated die-cast aluminum.  The electromagnetic flowmeter can be fitted with cross-drilled screws and seal wire for tamper-evidence.  Flow rate and total can be displayed on the electromagnetic flowmeters in a variety of units, customer-selected and factory-set. The WMP-Series electromagnetic flowmeters are used for tracking flow rate and total flow in usage monitoring applications, for instance, in compliance with regulatory requirements.  These would include wells, industrial wastewater, heap leach mining discharge, cooling tower deduct metering, turf and landscape applications, and other water reclamation operations.  In the event of DC power loss, or when changing the battery, the electromagnetic flowmeter is designed to retain the internal settings and flow total. The WMP101 electromagnetic flowmeter is externally powered via a 5-pin connector and the 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. The WMP104 electromagnetic flowmeter is a battery-operated unit for use when pulse output is not required.  The batteries are user replaceable with an approximate 1-year life under continuous use of the electromagnetic flowmeter, or more depending on the duty cycle. Please note that if you plan to use the AO55 blind 4-20mA converter or the FT420W pulse to 4-20mA output and display you must purchase the WMP electromagnetic flowmeters with the -HF, high frequency, option.
