Description
The WMX-Series are fanged electromagnetic flowmeters for use in 4” 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 magnetic flow meter 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 meter should be placed upstream of the injection line or far enough downstream for thorough mixing to occur before the meter. 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 7-26 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 should exceed 10 years.
The 20-foot power cable also provides pulse output for use with a variety of Seametrics and other displays and co ntrols 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. The Lithium 3.6V “D” batteries 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.
