Description:
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.

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.
