The MASTER METER B12 is a 5/8-inch threaded water meter designed for accurate water measurement in residential and light commercial water distribution systems. This meter ships without a meter coupling, so the appropriate coupling must be sourced separately before installation. The B12 uses a threaded connection style, making it compatible with standard threaded meter setups commonly found in municipal and private water service applications. Licensed plumbers and utility contractors are the primary installers of this type of meter.
The B12 is suited for residential service lines and light commercial applications where a 5/8-inch meter is the specified size. It is a direct-read, threaded-style water meter appropriate for new installations and meter change-out programs. Because the meter coupling is not included, this unit is well suited for situations where an existing coupling is being reused or a specific coupling type is required by the local utility.
Designed as an OEM-style replacement or new-installation water meter for residential and light commercial threaded meter applications requiring a 5/8-inch meter body without an integrated coupling.
Installation should be performed by a licensed plumber or certified water utility technician in accordance with local plumbing codes and utility requirements. Shut off the water supply and depressurize the service line completely before removing an existing meter or installing this unit. A meter coupling appropriate for the service line must be obtained separately and installed per the coupling manufacturer's specifications. Do not overtighten threaded connections, as this may damage the meter body or threads.
