WMP Plastic Bodied Electromagnetic Flow Meters

GENERAL INFORMATION

The WMP-Series seametrics flow meters is a full-bore, plastic-bodied electromagnetic flow meters designed for flow and usage monitoring applications in 1, 2 and 3 inch pipe.  The polypropylene flow tube offers cor-rosion 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 magnetic flow meters can be used in piping configurations where there is little space between the meter and an elbow or valve. The WMP-Series electromagnetic flow meters is resistant to wear from sand and debris found in ground or surface water.  Since there are no bearings or pro-peller 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 total can be displayed in a variety of units, customer-selected and factory-set.

Plastic-Bodied Magmeter
Electromagnetic Flow Meter
Seametrics Flow Meters

FEATURES

• No moving parts
• Minimal straight pipe required
• Battery powered
• Built-in rate & total indicator
• Corrosion resistant
• Pulse output (WMP101 only)




APPLICATIONS

Usage monitoring, such as:
• Industrial wastewater discharge
• Grey water
• Well monitoring
• Irrigation

The WMP-Series magnetic flow meters is used for tracking flow rate and total flow in usage monitoring applications including wells, industrial waste-water, 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 magnetic flow meter will retain internal settings and flow total.The  WMP101 flow meters 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 flow meters 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.*Includes Seametrics NPT fitting kit on 2” and 3” models.
