Additional Information
The magmeter permits unobstructed flow, minimizing flow disturbances and straight pipe requirements. The WMPSeries 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. 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 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-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. 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.
WMP Series Specifications
Full-bore electromagnetic flow meters for 1-, 2-, and 3-inch pipe. Choose the externally powered WMP101 when a pulse output is required, or the battery-powered WMP104 for stand-alone local indication.
External Power + Pulse Output
10–30 VDC power with an optically isolated pulse output for remote displays, data logging, controls, and telemetry.
Battery-Powered Operation
Self-powered local rate and total indication. Standard battery life is approximately one year; an extended-life option is available.

Typical Applications
The corrosion-resistant, unobstructed flow path makes the WMP Series well suited to conductive water and wastewater applications where sand, debris, or limited straight-pipe space can challenge mechanical meters.
Industrial Wastewater
Monitor discharge flow and accumulated volume in conductive industrial wastewater lines.
Greywater Systems
Measure reclaimed or non-potable water used for reuse, transfer, or facility water management.
Well Monitoring
Track pumping rate and totalized production from groundwater wells and related piping.
Irrigation
Measure water usage in irrigation systems, including water containing fertilizers or suspended debris.
Mining Water
Measure process, transfer, or site water where a meter with no moving parts helps reduce maintenance.
