GEnERAL InFORMATIOn

The WMP-Series is a full-bore, plastic-bodied electromagnetic 

flow meter designed for flow and usage monitoring applica-

tions in 1 and 2 inch pipe.  The polypropylene flow tube of-

fers corrosion resistance to a wide range of chemicals.  Its 

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 hence, straight pipe 

requirements.  The WMP-Series can be used in piping con-

figurations where there is little space between the meter and 

an elbow or valve.  The WMP-Series, like other magmeters, 

are resistant to wear from sand and debris found in ground 

or surface water.  Since there are no bearings or propeller to 

wear out, downtime and maintenance and repair costs are 

kept to a minimum. Because there are no mechanical parts 

in the flow stream, the meter tolerates high flows without 

damage.

The hinged, opaque polyethylene cover protects from dust 

and UV rays, while permitting easy access to the LCD flow 

rate and total display. The electronics housing is made of 

rugged powder-coated die-cast aluminum. It 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 WMP-Series is used for tracking flow rate and total flow 

in usage monitoring applications, for instance, in compliance 

with  regulatory  requirements.    These  would  include  wells, 

industrial wastewater, heap leach mining discharge, cooling 

tower deduct metering, turf and landscape applications, and 

other water reclamation operations. In the event of DC power 

loss, or when changing the battery, the WMP is designed to 

retain the internal settings and flow total.

The 

WMP101

  is  externally  powered  via  a  5-pin  connector 

and the power cable 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  under  typical 

use.  An  Extended  Battery  Life  option  offers  an  estimated 

3-year life, depending on the duty cycle.
