GENERAL INFORMATION 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.
GENERAL INFORMATION FEATURES Continued Rate and total indicator Tamper-evident security seal & cross-drilled screws (2) for tamper-evidence Internal Data Logger (Optional) Power/Output cable port access, tamper-sealed (NOTE: WMX101 comes with standard 20’ cable installed) Powder-coated ductile cast iron body & electronics housing Glass filled molded plastic liner 316SS electrodes Flanges, ANSI 150 lb.

INSTALLATION and GROUNDING INSTALLATION Caution: These flow sensors are not recommended where installation fault may expose the flow sensor to boiler pressure and temperature. Maximum recommended temperature is 130˚ F. Positioning the Meter. These meters can be installed horizontally, vertically, and in any radial position.

INPUTS/OUTPUTS and OPERATION WMX101 External Power (WMX101). The WMX101 operates on 8-32 Vdc at 30 mA max external power (see WARNING in wiring diagrams). The display reads “P” when external power is in use (see illustration below). The Lithium battery pack installed in the WMX101 serves as backup in the event of a power failure, when it will keep the meter operating without interruption for the duration of the outage.
CONNECTIONS DIAGRAMS (WMX101) The WMX101 requires a power source of 8 to 32 Vdc at 30 mA max (see WARNING). The WMX101 power cable also serves as a pulse output if needed for remote reading, data logging, signal conversion, or telemetry.
