Recordall® Turbo 450 Fire Hydrant Meter Technical Brief Size 3" (DN 80 mm) DESCRIPTION APPLICATIONS: For use in measurement of potable cold water from a fire hydrant or other non-permanent installation where flow is in one direction only. OPERATION: Water flows into the meter's measuring element where flow readings are obtained by rotor revolutions transmitted by magnetic drive coupling through the meter's cover plate to the sealed register. Magnetic drive is achieved by a right angle worm drive, coupling the rotor to the vertical transmission spindle. A ceramic magnet on the spindle rotates around the vertical axis. Through the magnetic coupling, rotor rotation is transmitted to a follower magnet which transmits rotation to the register gearing. OPERATING PERFORMANCE: The Badger Recordall Turbo Series fire hydrant meters meet or exceed registration accuracy for the low flow rate, normal operating flow rate, and maximum continuous operation flow rate as specifically stated in AWWA Standard C701. CONSTRUCTION: Badger Recordall Turbo Series fire hydrant meter construction consists of three basic components: meter housing, measuring element and permanently sealed register. The housing is light-weight heat treated aluminum alloy, compact and easy to handle. The measuring element consists of the transmission coupling, measuring element insert, rotor, straightening vane, and calibration vane assembly. The straightening vanes minimize swirl from piping arrangements upstream. MAGNETIC DRIVE: Direct magnetic drive, through the use of highstrength magnets, provides positive, reliable and dependable register coupling. RESTRICTION PLATE: A permanent orifice, positioned in the outlet side of the housing, limits the maximum flow of water through the meter. This is provided to protect the measuring element from overspeeding when the meter discharges to atmosphere. SEALED REGISTER: The standard register consists of a straightreading odometer-type totalization display, 360° test circle with center sweep hand and flow finder to detect leaks. Register gearing consists of self-lubricating thermoplastic gears to minimize friction and provide long life. Permanently sealed; dirt, moisture, tampering and lens fogging problems are eliminated. Multi-position register simplifies meter installation and reading. TAMPER-RESISTANT FEATURES: Removal of the register to obtain free water is prevented when the tamper detection seal wire screw or TORX® tamper resistant seal screw is added to the meter. A tamper resistant calibration plug seal provides protection from unauthorized personnel use. STRAINER: A compression fit double layer stainless steel strainer is installed in the inlet housing tube. The strainer insures optimum longterm field performance. MAINTENANCE: Badger Recordall Turbo Series fire hydrant meters are designed and manufactured to provide long-term service with minimal maintenance. When maintenance is required, it can be performed easily either at the meter installation or at any other convenient location. As an alternative to repair by the utility, Badger offers various maintenance and meter component exchange programs to fit the needs of the utility. HOSE COUPLINGS: The meter is available with standard (2½"-7 NST) fire hose swivel couplings as standard equipment unless otherwise specified. Complete thread specifications (listed on back page) must be furnished for special fire hose fittings. OPTIONS: 2" gate valve, 2½" gate valve, check valve.
