Multi-Jet Dry-Dial Water Meter
The KBN Multi-Jet Water Meter operates on the velocity principle where water enters the measuring chamber through multiple tangential ports. This distributes hydraulic pressure equally across all impeller vanes, dramatically reducing bearing wear and ensuring exceptional low-flow sensitivity and measurement stability over years of continuous service.
The dry dial register is completely isolated from water contact by an O-ring sealed brass gland and driven magnetically. Selected high-density virgin materials resist scaling, algae adhesion, and exterior magnetic tampering.

Multi-Jet Hydraulic Balance
Equalized flow entry around the circumference minimizes radial thrust on the jewel pivot bearing for unmatched longevity.
Fog-Free Hermetic Register
The register operates in air and is completely separated from water to guarantee crystalline readability throughout life.
Anti-Tamper Shielding
Magnetic shield casing neutralizes outside magnet attempts to slow or freeze register counters.
