Seametrics WMP Series Plastic Electromagnetic Flow Meter

Description

Seametrics WMP Series Plastic Electromagnetic Flow Meter is a lightweight, full-bore plastic electromagnetic flow meter designed for 1-to-3-inch pipes, offering high corrosion resistance to chemicals and fertilizers due to its polypropylene flow tube. With no moving parts or bearings to wear out, it provides unobstructed flow and minimal maintenance even in water containing sand or debris, while its compact design allows for installation in tight piping configurations. The series features a protective hinged cover and tamper-evident electronics housing, with models like the WMP101 providing external power and pulse output for remote monitoring, and the WMP104 offering a battery-operated solution for locations without a power source.
