The OMNI meter is the most technologically advanced large water meter on the market today. The key to this optimal measurement performance is the application of the new Floating Ball Technology (FBT). FBT employs an impeller with a ball design which makes the impeller weightless in the water line. The technology enables the impeller to begin moving with very little water flow or force through the meter. The result is that OMNI has an extended flow range with better low flow sensitivity, as well as the ability to capture extended high flow rates - all with virtually no wear.

The F2 meter is ideal for use in limited vault space situations to service lines supplying both fire protection and domestic water. The F2 attacks head-loss and maintenance issues. The product is Underwriters Laboratories (UL) Listed and Factory Mutual (FM) approved.

Conformance To Standards

The OMNI F2 meter meets and far exceeds the most recent revision of AWWA Standard C703 class II. Additionally, the meter does not require a valve to meet these standards. Each meter is performance tested to ensure compliance. All OMNI meters are NSF/ANSI Standard 61, Annex F and G approved. The OMNI F2 meter is UL (Underwriters Laboratories) Listed and FM (Factory Mutual) approved for use on fire protection and domestic water applications. 


The patented measurement principles of the OMNI F2 meter assure enhanced accuracy ranges, an overall greater accuracy, and a longer service life than any other comparable class meter produced. The F2 meter has no restrictions as to sustained flow rates within its continuous operating range. The floating ball measurement technology allows for flows up to its rated maximum capacity without undue wear or accuracy degradation. 


The OMNI F2 meter consists of two basic assemblies; the maincase and the mea- suring chamber. The measuring chamber assembly includes the “floating ball” impeller with a coated titanium shaft, hybrid axial bearings, integral flow straightener and an all electronic programmable regis- ter with protective bonnet. The maincase is made from industry proven Ductile Iron with an approved NSF epoxy coating. Maincase features are; easily removable measuring chamber, unique chamber seal to the main case using a high pressure o-ring, testing port and a convenient integral strainer with optional drain/debris- flushing ports. 

Omni Electronic Register

The OMNI F2 electronic register is hermetically sealed with electronic pickup containing no mechanical gearing. The large character LCD displays AMR, Totalization and a Resettable Test Totalizer. OMNI register features; AMR resolution units that are fully programmable, Pulse output frequency that are fully program- mable, Integral customer data logging capability, Integral resettable accuracy testing feature compatible with the UniPro Testing Assistant Program, Large, easy-to-read LCD also displays both forward and reverse flow directions and all with a 10-year battery life guarantee. 

Magnetic Drive

Meter registration is achieved by utilizing a fully magnetic pickup system. This is accomplished by the magnetic actions of the embedded rotor magnets and the ultra sensitive register pickup probe. The only moving component in water is the “floating ball” impeller. 

Measuring Element

The revolutionary thermoplastic, hydro dynamically balanced impeller floats between the bearings. The Floating Ball Technology (FBT) allows the measuring element to operate virtually without friction or wear, thus creating the extended upper and lower flow ranges capable on only the OMNI F2 meter. 


The OMNI F2 meter includes the Sensus designed “V” shaped UL Listed/FM approved strainer which utilizes a stainless steel screen along with Floating Ball Technology (FBT) to create a design that gives far improved accuracy even in those once thought questionable settings. A removable strainer cover permits easy access to the screen for routine maintenance. Optional drain ports, located at the back lower corners of the strainer body, allow for easy discharging of debris without the need to remove the cover. 


The OMNI F2 meter is designed for easy maintenance. Should any maintenance be required, the measuring chamber and/ or strainer cover can be removed independently. Parts and or a replacement measuring chamber may be utilized in the event repairs are needed. Replacement Measuring Chambers are available for the OMNI F2 meters.
