  • Digital flowmeter
    Patent number: 4157660
    Abstract: A bearingless digital flowmeter consists of toroid-shaped cavity and of tangential inlet/outlet channels. A ball in the cavity revolves in proportion to the flow rate. The frequency of revolution of the ball is detected by photoelectric or magnetic pickup device. The flowmeter is linear even at small flow rates and measures flow in both directions. The inlet and outlet are on opposite sides of the toroid in opposed relationship, which not only improves accuracy, but permits the meter to register flow in either direction.
