OPERATION:
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 hermetically sealed register. Powerful rare earth magnets eliminate slipping and uncoupling to increase overall accuracy.
gear train which translates the impeller’s rotation into volume totalization displayed on the register dial face.CONSTRUCTION:
ZENNER PMN Water Meters consist of three basic components: main case, measuring cham- ber and sealed register. The main cases are constructed using either C89833 or C89850 Brass Alloys. Measur- ing Chambers are constructed of a durable synthetic polymer. Registers are available as either direct read or electronic output.
MAINTENANCE:ZENNER PMN Water Meters are engineered and manufactured to provide long-term service and operate virtually maintenance free. The precise simple design allows for interchangeable parts, reducing parts inventory.
REGISTRATION:
ZENNER PMN Water Meters utilize a magnetically driven, hermetically sealed design. The sealed design eliminates dirt, moisture infiltration, and prevents fogging. The register includes a large odome- ter-type totalization display, center sweep hand (360°) test circle, low flow leak detector. All ZENNER Metershave electronic output capabilities for easy conversion to Automated Meter Reading. 5/8” through 1” capacities are: 10,000,000 Gallons, 1,000,000 Cubic Feet, 100,000 Cubic Meters, 6 odometer wheels. 1 1/2” and 2”registration capacities are: 100,000,000 Gallons, 10,000,000 Cubic Feet, 1,000,000 Cubic Meters, 6 odometer wheels.CONFORMANCE:
ZENNER PMN Water Meters are tested and comply with AWWA C708, ISO 4064, and G13IT19001-ISO9000 performance standards. These Meters comply with the lead-free provisions of the Safe Drinking Water Act and are certified to NSF/ANSI Standards 61 and 372.TAMPERPROOF FEATURES:
Customer removal of the register to obtain free water is prevented through the use of a locking device that requires a special tool, only available to water utilities.CONNECTIONS:
These meters have been designed with ease of installation in mind through the use of built-inwrench pads on meter sizes 5/8” through 1”. Tailpiece/Unions for installations of meters are available as anoption for various pipe types, sizes, and misaligned pipes. The 1-1/2” PMN09 and 2” PMN12 flanged meterscome with a built-in 1” test port.
