GENERAL INFORMATION and FEATURES
GENERAL INFORMATION
The WMP-Series is a full-bore, plastic-bodied electromagnetic
ow meter designed for ow and usage monitoring applications
in 1, 2 and 3 inch pipe. The polypropylene ow tube offers 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 ow,
minimizing ow disturbances and hence, straight pipe requirements. The WMP-Series can be used in piping congurations
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 ow stream, the
meter tolerates high ows without damage.
The hinged, opaque polyethylene cover protects from dust and
UV rays, while permitting easy access to the LCD ow rate and
total display. The electronics housing is made of rugged powder-coated die-cast aluminum. It can be tted 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 ow rate and total ow in
usage monitoring applications, for instance, in compliance with
regulatory requirements. These would include wells, industrial
wastewater, gray water, irrigation 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 ow 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 1-2 year life depending on
usage. An extended battery life option offers an estimated 2-4
year life depending on usage.
