  • Patent number: 8019559
    Abstract: A flow meter and method for measuring flow in liquids which may have entrained bubbles or foreign matter. The meter performs alternate transit time and Doppler measurements. The transit time measurements are used to calculate flow so long as they are successful. If the transit time measurements are not successful, the Doppler measurements are used.

  • Patent number: 6012339
    Abstract: A flow meter is provided that can be used to measure the flow of fluids from a fluid source to a receiving system, and methods of using the flow meter to measure fluid flow. The flow meter is composed of a housing that contains a fluid flow sensing member in the form of a rotatable bladed rotor or turbine in one chamber and a sensor and a signal-conditioning circuit in a second separate chamber. The rotor rotates by fluid flow through the housing chamber. The rotor preferably contains a magnet that passes over a magnetically-operated sensor and triggers it to produce a signal that is processed by the conditioning circuit into a 4-20 mA output signal that indicates a range from no flow to full flow of the liquid through the flow meter.
