US Patent:

7308824, Dec 18, 2007

Filed:

Feb 17, 2006

Appl. No.:

11/356732

Inventors:

Frank W. Collurafici - Escondido CA, US
Frank P. Collurafici - Escondido CA, US
Scott Shaw - Brentwood TN, US

Assignee:

Sentinel Hydrosolutions, LLC - San Marcos CA

International Classification:

G01F 1/68

US Classification:

7320411

Abstract:

A thermal dispersion flow meter with chronometric monitor for fluid leak detection includes an ambient temperature RTD sensor and a flow rate RTD sensor which are configured to sense the temperature of a fluid in a conduit, and then monitor the flow of that fluid through the conduit. The fluid flow RTD sensor is incorporated into a Wheatstone bridge circuit which is used to provide increased sensitivity to the outputs of the RTD sensors. Based upon the ambient temperature sensor readings, the flow rate RTD sensor may be adjusted to optimize the operation of the system to detect leaks, and on certain conditions, a controller may close a supply line valve to avoid flooding of a structure.

Abstract:

A non-invasive thermal dispersion flow meter with chronometric monitor for fluid leak detection includes a heater, an ambient temperature sensor and a flow rate sensor which are configured to sense the temperature of a fluid in a conduit, and then monitor the flow of that fluid through the conduit. The fluid flow sensor is incorporated into a Wheatstone bridge circuit, which is used to provide increased sensitivity to the outputs of the sensors, Based upon the ambient temperature sensor readings, the flow rate sensor and heater may be adjusted to optimize the operation of the system to detect leaks. An alternative embodiment utilizes a single sensor and separate heater which work together to determine heat propagation times which in turn is used to calculate flow rate. Based on the sensor readings, the flow may be adjusted to prevent damage and leaks by relieving the system of excess pressure.
