OMNI™ Fireline Water Meter

When you’re faced with limited vault space, the OMNI™ Fireline (F²) commercial meter is ideal. We designed this meter to make maintenance easier on both fire protection and commercial water lines. The OMNI F² is certified, so you can be confident functionality will be there when you need it most.

The measurement principles of the F² meter assure enhanced accuracy ranges and a longer service life than any other comparable meter. It has no restrictions as to sustained flow rates within its continuous operating range.

The F² Fireline Bypass Retrofit meter can easily replace Sensus legacy W-Series compact and standard Fireline bypass meter assemblies.

OMNI meters are the most technologically advanced, large commercial water meters on the market. They provide longer service life than any other comparable meter.

All of our OMNI meters use floating ball technology (FBT). This is key to its optimal measurement performance. FBT uses an impeller with a ball design. The impeller is weightless in the water line. This feature enables the impeller to begin moving with very little water flow or force through the meter. As a result, OMNI meters have an extended flow range with greater low-flow sensitivity. They also have the ability to capture extended high-flow rates, all with virtually no wear on the meter.
