OMNI Fireline (F²) Water Meter
Advanced fire protection and commercial water meter designed for limited vault space applications. Features patented floating ball technology (FBT) for superior accuracy and extended service life. Ideal for both fire protection and commercial water lines with extended flow range and greater low-flow sensitivity. Single moving part design ensures virtually no wear throughout operational lifetime. Includes 180 days data logging, integral test port, and resettable totalizer. Electronic register with no mechanical gearing, fully magnetic pickup system, and configurable LCD display. Compatible with Sensus AMI/AMR systems with NFC capability for dead battery readings. AWWA C703 Class II certified with NSF/ANSI 61 approval. 10-year battery warranty. Can retrofit Sensus legacy W-Series compact and standard Fireline bypass meter assemblies.
