WMP-Series WMP-SERIES PLASTIC-BODIED MAGMETER INSTRUCTIONS PLASTIC-BODIED MAGMETER INSTRUCTIONS 3 inch 2 inch ISO 9 0 0 1 : 2 0 0 8 CERTIFIED COMPANY 1 inch
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, 2 and 3 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.

ELECTRICAL CONNECTIONS, CABLE CONNECTIONS and OPERATION ELECTRICAL CONNECTIONS WMP104. The WMP104 is battery-powered totally self-contained and does not require any electrical connections (there is no output on the WMP104 model). CABLE CONNECTIONS Gray: Pin 5 = Ground White: Pin 4 = (–) Pulse Blue: Pin 3 = (+) Pulse Black: Pin 2 = (–) Power Brown: Pin 1 = (+) Power Shield Drain Wire OPERATION Grounding (WMP101).
MAINTENANCE, REPAIR and TROUBLE SHOOTING MAINTENANCE AND REPAIR There are no user-serviceable parts in the WMP-Series meters except the batteries in the WMP104. Battery Replacement. When the “low bat” indicator appears, the batteries should be changed. Either six each AA alkaline cells are required, or two each C lithium cells with integrated wiring harness, depending on power option ordered with meter. To change the batteries, first remove the four screws which hold the top cover in place.
