Plastic Bodied Electromagnetic Flow meter

The Plastic Bodied Electromagnetic Flow meter WMP-Series is a full-bore, plastic-bodied electromagnetic flow meter designed for flow and usage monitoring applications in 1, 2 and 3-inch pipe. The polypropylene flow tube offers corrosion resistance to a wide range of chemicals and fertilizers. It is lightweight and easy to install or remove from the pipe for inspection. WMP ELectromagnetic Flow meter

With no moving parts, the Electromagnetic Flowmeter permits unobstructed flow, minimizing flow disturbances and straight pipe requirements. The Electromagnetic Flowmeter WMP Series can be used in piping configurations where there is little space between the meter and an elbow or valve. The Electromagnetic Flowmeter WMP-Series is resistant to wear from sand and debris found in-ground or surface water. 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. A hinged polyethylene cover is included that protects from dust and UV rays while permitting easy access to the flow rate and total display. The electronics housing can be fitted with cross-drilled screws and seal wire for tamper-evidence. Flow rate and the total can be displayed in a variety of units, customer-selected, and factory-set. The Electromagnetic Flowmeter WMP 101 is externally powered via a 5-pin connector cable (20 ft/6m)which also provides pulse output for use with a variety of Seametrics and other displays and controls for remote reading, data logging, pulse-to analog conversion, and telemetry applications. The WMP104 is a battery-operated unit for use when pulse output is not required. The standard batteries are user replaceable with an approximate 1-year life depending on usage.
