PRODUCT INFORMATION
Product Description
The Recordall Turbo Series meters use proven design features such as thrust-compensated rotor geometry, direct drive
magnetic coupling, and dual outboard rotor bearings to achieve high accuracy over a broad flow range. Extended product
service life is achieved at higher levels of accuracy, in addition to lower meter maintenance costs. The Turbo meters are
available in 1-1/2", 2", 3", 4", 6", 8", 10", 12", 16" and 20" sizes.
Incorporating unitized construction with corrosion-resistant assemblies, the basic components of the Recordall Turbo Series
consist of the housing and the completely removable measuring element. The meter housing and cover plate are lead-free
bronze (1-1/2" to 10" sizes). The 12" to 20" meter housings are cast iron with a heat fused epoxy coating. The measuring
element is constructed of high-impact strength thermoplastics. Recordall Turbo Series meters are also equipped with an
integral calibration mechanism for in-line accuracy calibration.
In the operation of a turbo meter, water flows through the straightening vanes and a nose cone at the inlet side of the meter
so that the swirling effect of upstream piping is minimized. The water then strikes the rotor blades, causing the rotor to turn. A
downstream nose cone includes straightening vanes to limit the downstream effects of flow profile distortions. Optional NPT
test ports are provided for field performance testing.
Motion of the rotor is transferred by means of a worm drive to a vertical shaft driving a gear set, which transmits the rotation
to the meter's registration device. The direct drive magnetic coupling provides accurate flow registration during line surges,
and allows the permanently sealed register to be easily removed to facilitate in-line service.
Accessories
Meters and encoders are compatible with Badger Meter AMR/AMI meter reading systems and other approved reading
technologies. AMR/AMI solutions are available for all Recordall Turbo Series meters. All reading options can be removed from
the meter without disrupting water service. Badger Meter encoders provide years of reliable, accurate readings for a variety of
applications and are also available pre-wired to Badger Meter approved AMR/AMI solutions. See details at
www.badgermeter.com.
A strainer is recommended to provide optimal flow conditioning and protection for the measuring element. An integral
strainer is available as an option for 1-1/2" through 4" meter sizes. The stainless steel strainer is built into the inlet end
and includes a removable cover plate to permit easy access for routine cleaning. External strainers are available in sizes 2"
through 12".
