  • Patent number: 10962393
    Abstract: An ultrasonic transceiver array provides for measurement and determination of flow rate of oil, water and gas in a multiphase flow in a pipe or conduit. The transceiver array is mounted externally and non-invasively in an elliptical arrangement on the pipe surface, resulting in an ellipsoid section of the flow cross-sectional area to be interrogated. The single ultrasonic transceiver array forms a tomographic image of multiphase flow to determine volume fraction of each phase; measure the total flow velocity to determine flow rate of individual phases and thus provide a three phase measurement capability. Both phase fractions and flow velocities can be determined at the same time, eliminating the need for two different systems to achieve that purpose.

  • Publication number: 20150143917
    Abstract: The invention relates to a method of detecting a buildup of silt in a pipe or open channel of a fluid flow network. The pipe or open channel has a system with at least one set of velocity sensors to measure flow velocities at predetermined horizontal levels. The method includes the steps of computing flow using measured flow velocities and cross-sectional areas for each flow layer, summing the flows to provide a total flow, monitoring the measured flow velocities and storing the measured flow velocities to detect any ongoing reduction in flow velocity of at least a lowermost velocity sensor to provide an indication of a buildup of silt in the pipe or open channel.

  • Patent number: 9035781
    Abstract: A gas appliance monitoring apparatus for automatically detecting and alerting to a “gas-out” condition of a gas appliance during operation, and/or for alerting to the presence of prolonged “gas-on” conditions of an appliance. The apparatus utilizes a highly sensitive low loss and low flow gas flow indicator with multiple flow sensors to monitor the gas flow characteristics of the appliance during use. A gas flow analyzer and alarm timing mechanism analyzes the gas flow characteristics and sounds an alarm at the appliance or wirelessly at a remote location upon detection of either of the above conditions. A biasing attraction magnet is incorporated in the fluid flow indicator to offset either the force of gravity or a return spring in low flow/low pressure applications. The piston is sealed for use in high pressure/low flow applications, and provided with a vent hole for residual gas bleed-off upon a stoppage of gas flow.

  • Publication number: 20150128720
    Abstract: A system and method to monitor and/or control the operation of a fluid transferring system that does not require the use of a realtime fluid sensor. The system relies on a feedback control mechanism that provides the operating conditions of the flow regulator. Based on the information relating to the state of the flow regulator, the system is able to provide information regarding the fluid state such as flow rate. This is accomplished through the use of pre-recorded correlations between flow regulator settings and resulting fluid conditions.
