GENERAL INFORMATION
FEATURES
The WMX-Series are flanged electromagnetic flowmeters
for use in 3” to 10” pipe in municipal or industrial water and
wastewater applications where propeller meters have typically
been used in the past. Because the WMX has no moving
parts and has electrodes designed to discourage fouling, this
magmeter performs well and requires much less frequent
maintenance in applications where debris would impede
propeller meters. There is no rotor to stop turning or bearings
to wear out. Minimal straight pipe requirements allow WMX-
Series meters to be used in piping configurations where there
is little space between the meter and an elbow.
In chemical injection applications, the chemical injection point
must be placed downstream of the magmeter OR far enough
upstream for complete mixing to occur before the fluid
reaches the meter.
The submersible units, -168 option, are rated IP68 (NEMA 6P)
for applications where the meter may be under water up to a
depth of 3 meters for prolonged periods of time.
Rate and total indication are standard on both models. Units
are customer-selected and factory-set. No set-up is required.
The WMX101 is externally powered with 8-32 Vdc at 30
mA max (see NOTE in Specifications). Two Lithium 3.6V
“AA” batteries provide auxiliary power during power failures,
allowing the meter to continue recording flow rate and total
without interruption for the duration of the outage. Where
external power loss is infrequent, battery life exceeds 10 years.
The 20-foot 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. High frequency pulse rate (required
for use with 4-20 mA converters) is standard; additional pulse
rates are optional.
The WMX104 is a battery-operated unit for use when pulse
output is not required. Two Lithium 3.6V “D” batteries provide
power and are replaceable with an approximate 1-year life
under continuous use, or more depending on the duty cycle.
An optional input/output cable can be installed post-factory if
needed for changing applications.
