WM Residential Water Meters/Submeters
The WM Series residential water meters are multi-jet (inferential) impeller meters. They measure total flow in gallons. The impeller and magnet are the only moving parts in the measuring chamber. The chamber is located in a strainer basket, which allows for high amounts of impurities to be passed through the meter without affecting its operation. The impeller movement is transferred by a magnetic coupling to the hermetically sealed register. These are perfect for submetering water in multi unit apartments & commercial buildings.

Residential Water Meter Construction
These residential water meters consist of an epoxy coated forged bronze housing which has the size and flow direction cast into it, and includes an integral strainer/measuring chamber. The register is hermetically sealed, and can be removed. The register is protected by a tempered glass lens, as well as a hinged metal cover. There is a calibration port which is securely sealed after factory testing and calibration.
