  • Recirculation type oscillator flow meter
    Patent number: 8201462
    Abstract: The present invention discloses a recirculation type hydrodynamic oscillator flow meter for measuring the flow of fluids such as gas, air, water and oil, flowing through a conduit. This flow meter gives very accurate measurements over a long period of time since piezoelectric sensors are employed. The principle of working of this hydrodynamic oscillator flow meter is the generation of a self induced jet where the frequency of oscillations of the fluid jet is proportional to the flow rate.
    Type: Grant

  • Fluidic oscillator flow meter
    Patent number: 8091434
    Abstract: The present invention discloses a feedback type, hydrodynamic oscillator flow meter for measuring the flow of fluids such as gas, air, water and oil, flowing through a conduit. This flow meter gives very accurate measurements over a long period of time since piezoelectric sensors are employed. The working principle of this flow meter is based on the Coanda Effect, which guides the flowing fluid to pass through two feedback paths (103, 129) alternatively and a linear relationship is obtained between the fluidic oscillation frequency and the flow rate.
