The Seametrics WMP Series Plastic-Bodied Magmeter 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 (includes Seametrics NPT fitting kit on 2" and 3" models).
With no moving parts, the magmeter permits unobstructed flow, minimizing flow disturbances and straight pipe requirements. The WMP Series magmeter can be used in piping configurations where there is little space between the meter and an elbow or valve. The 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 crossdrilled 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 WMP Series is used 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. In the event of DC power loss, or when changing batteries, the WMP will retain internal settings and flow total.
The WMP101 is externally powered via a 5-pin (20ft/6m) connector cable 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 1-2 year life depending on usage. An extended battery life option offers an estimated 2-4 year life depending on usage.

Here's how some of our customers used this product.
Creek Water Monitoring for Irrigation
The Background: Our customer is a farmer in California who draws the water used for irrigation from a creek on his property. The state has recently required he report how much water he takes from the creek.
The Problem: The water is gravity fed from the creek to a storage tank. This setup is located at a remote corner of the property without access to line power. Solar was considered but battery is far more simple and straightforward.
The Solution: The Seametrics WMP magnetic flow meter is an obvious choice as it is relatively low cost and uses common alkaline batteries which last for up to two years. The WMP is open bore with no moving parts so debris from the creek will pass right through. The State will like that the WMP has no configuration buttons and so the onboard totalizer cannot be reset.
