Single Jet water meter working principle:
The single jet meter
consists of bronze, brass, or an alloy body. Inside there is a measuring
impeller and a camera slightly offset from the center. Water flow connection.
Water entering the box enters the impeller chamber through one hole. Water
flows through the tangential wheels to maintain the rotating shaft. This rotation
drives the clutch on the magnetic field recording head.
