WMP-SERIES INSTRUCTIONS
The WMP-Series meters are full-bore, plastic-bodied
electromagnetic ow meters 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. It’s 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
congurations where there is little space between the meter and an elbow or valve. The WMP-Series meters 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, 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 diecast 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 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.
In the event of DC power loss, or when changing the
battery, the WMP is designed to retain the internal settings
and ow total.
