  • Leak detection in fluid conducting conduit
    Patent number: 9037422
    Abstract: A method for detecting a leak in a fluid conducting conduit is disclosed. Inlet and outlet flowrates are measured for calculating a time derivative of average temperature of the fluid flowing in the fluid conducting conduit. A predicted difference in flowrate between a flowrate of fluid in the fluid conducting conduit adjacent the inlet and a flowrate of fluid in the fluid conducting conduit adjacent the outlet is calculated based on the calculated time derivative of the average temperature of the fluid flowing in the fluid conducting conduit. The predicted difference in flowrate is compared to a difference between the measured inlet flowrate and the measured outlet flowrate to determine whether a leak exists in the fluid conducting conduit.

  • System and method for leak detection based upon analysis of flow vectors
    Patent number: 7418354
    Abstract: A method for detecting a leak in a fluid-conducting conduit is disclosed herein. The method includes generating a first flow vector variation pattern representative of fluid flow through the conduit under known conditions. The method also includes collecting flow data from flow sensors positioned along the conduit. In addition, a second flow vector variation pattern is generated based upon the flow data. The first flow vector variation pattern and the second flow vector variation pattern are then compared in order to detect whether a leak exists in the conduit.
