Plastic water meter


Plastic Water Meters/Submeters

The WM-PC Series plastic water meter is an impeller style meter available in sizes from 1/2" to 1-1/2" with a dry type register for residential applications and designed to meet AWWA C708.

Water flows through the meter's strainer (inlet and internal) and into the measuring chamber where it drives the impeller. A driving magnet transmits the movement of the impeller to a driven magnet located within the sealed register. The magnet is connected to a gear train which translates the impeller rotations into volume totalizers displayed on the meter’s register dial face.

The WM-PC Series water meter is top loaded and consists of three basic components: main case, measuring chamber, and head ring. The main cases of all sizes are constructed with a sturdy polymer.

All meters include pipe adapters (2 gaskets, 2 couplings, and 2 nuts) with nuts and couplings made from the same polymer as the main case, except the 1-1/2" which substitutes brass for the coupling material.
