GENERAL INFORMATION and FEATURES
GENERAL INFORMATION
The WMP-Series is a full-bore, plastic-bodied electromagnetic
flow meter designed for flow and usage monitoring applications in 1 and 2 inch pipe. The polypropylene flow 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
flow, minimizing flow disturbances and hence, straight pipe
requirements. The WMP-Series can be used in piping configurations 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, customerselected 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.
