Residential Fire Meters

Residential Fire Meters utilize a unique patented multi-jet and dual element strainer to measure low flow rates comparable to traditional positive displacement meters with the high flows required of residential fire service meters.

These Meters are designed for use in any application where residential fire suppression systems are being used. They are designed to measure cold potable water where flow is in one direction only in residential and domestic use applications.

OPERATION:
Water flows through the meter’s dual 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 two pole Rare Earth magnets eliminate slipping and uncoupling to increase overall accuracy. The magnet is connected to a gear train which translates the impeller’s rotation into volume totalization which is displayed on the register dial face. The design of these meter measuring elements allow suspended particulate matter to pass through the meter without locking up the meter and restricting the flow.

HIGH TEMPERATURE CONSTRUCTION:
ZENNER PERFORMANCE Residential Fire Meters consist of three basic components: main case, measuring chamber and sealed register. The main cases are constructed using C89833 Brass Alloy. Measuring Chambers, encapsulated in a dual element strainer (4 times the open inlet diameter or greater of strainer area) are constructed of a durable high temperature synthetic polymer. These meters can withstand super heated water back-flowing into the meter without melting and blocking the flow of water to the sprinklers located in the dwelling.

REGISTRATION:
ZENNER PERFORMANCE Residential Fire Meters utilize a magnetically driven, hermetically sealed design. The sealed design eliminates dirt and moisture infiltration as well as prevents fogging. The register includes a large odometer-type totalization display, center sweep hand (360°) test circle, low flow leak detector. All Performance Meters have electronic output capabilities for easy conversion to Automated Meter Reading. 3/4” through 1” capacities are: 10,000,000 Gallons, 1,000,000 Cubic Feet, 100,000 Cubic Meters, 6 odometer wheels. 1 1/2” registration capacities are: 100,000,000 Gallons, 10,000,000 Cubic Feet, 1,000,000 Cubic Meters, 6 odometer wheels.

COMPLIANCE:
ZENNER PERFORMANCE Residential Fire Meters are tested and comply with ANSI/AWWA C703R Draft.

APPLICATIONS:
International building code, International fire code, International residential code, NFPA 101 life safety code, NFPA 5000 building construction and safety code, NFPA 1 uniform fire code and national fire sprinkler association standards NFPA 13D and NFPA 13R. The above listed codes all now require sprinkler protection for all new single family dwelling units, up to four stories in height.

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.
