CONSTRUCTION

The meter mainly consists of a body, a measuring chamber, a indicator with pulse transmitting device, a retaining ring with lid. The retaining ring secures the internal parts.

WORKING PRINCIPLE

The water flows through the meter's strainer and into the measuring chamber where it drives the impeller. A drive magnet transmits the motion of the impeller to a driven magnet located within the sealed indicator. The magnet is connected to a gear train which translates the impeller's rotation into volume totalization displayed on the register dial face.
