WMP-Series Magmeter by Seametrics

WMP Irrigation Magmeter by SeametricsPlastic Bodied Magmeter suitable for Agricultural & Industrial based applications

The SeaMetrics 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 light weight and easy to install or remove from the pipe for inspection. With no moving parts, the magmeter permits unobstructed flow, minimizing flow disturbances and straight pipe requirements. The WMP Series can be used in piping configurations where there is little space between the meter and an elbow or valve, it is also resistant to wear from sand and debris found in ground or surface water. As 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 a standard inclusion 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 total can be displayed in a variety of units, customer-selected and factory-set.

The WMP101 is externally powered via a 5-pin connector cable (20ft/6m) which also provides pulse output for use with a variety of Seametrics and other displays and controls for remote reading, data logging, pulse-toanalog conversion, and telemetry applications. While 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. An extended battery life option offers an estimated 2-4 year life depending on usage. In the event of DC power loss, or when changing batteries, the WMP will retain internal settings and flow total.

 

Applications: Industrial Wastewater discharge, Grey Water, Well Monitoring, Irrigation, Mining.
