The MASTER METER B16 is a 1-inch threaded water meter designed for measuring potable water flow in residential and light commercial plumbing systems. This meter ships without a meter coupling, meaning the coupling must be sourced separately or reused from an existing installation. The B16 uses threaded connections for straightforward inline installation and is sized for 1-inch service lines, a common specification in single-family residential and small commercial water service applications. Licensed plumbers and water utility contractors are the primary installers of this type of meter.
The B16 is suited for 1-inch water service line installations where a threaded-connection meter is required. Typical applications include residential water service entry points, irrigation metering, and light commercial submetering. Because this unit does not include a meter coupling, it is appropriate for replacement installations where the existing coupling is being retained, or for projects where the coupling is specified and ordered separately.
Designed as an OEM-style replacement or new-installation meter for 1-inch threaded water service line applications. No specific compatible model numbers or system families were provided in the product data.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and applicable sections of the IPC. Shut off the water supply and depressurize the line before removing the existing meter or making any connections. Do not overtighten threaded fittings — use appropriate thread sealant rated for potable water service. Verify that a compatible meter coupling is on hand before beginning the installation, as this unit does not include one.
