Patent number: 8974114Abstract: Apparatus and methods for verifying temperature measurements in an ultrasonic flow meter. In one embodiment, an ultrasonic flow metering system includes a passage for fluid flow, a temperature sensor, and an ultrasonic flow meter. The temperature sensor is disposed to measure temperature of fluid flowing in the passage. The ultrasonic flow meter includes a plurality of pairs of ultrasonic transducers and control electronics. Each pair of transducers is configured to form a chordal path across the passage between the transducers. The control electronics are coupled to the ultrasonic transducers. The control electronics are configured to measure speed of sound between each pair of transducers based on ultrasonic signals passing between the transducers of the pair. The control electronics are also configured to determine, based on the measured speeds of sound, whether a measured temperature value provided by the temperature sensor accurately represents temperature of the fluid flowing in the passage.Type: GrantFiled: May 2, 2012Date of Patent: March 10, 2015Assignee: Daniel Measurement and Control, Inc.Inventors: Charles W. Derr, Henry C. Straub, Jr.

Patent number: 8626466Abstract: Flow meter validation techniques are herein disclosed. An illustrative system includes a flow meter and display logic coupled to the flow meter. The flow meter is configured to provide information indicative of a parameter of fluid flow through the meter. The display logic is configured to provide a display of the information. The display includes an indication of a possible range of values of the parameter. An indication of a baseline portion of the range is also provided. The baseline portion of the range designates preferred values of the parameter. The display further includes an indicator designating the value of the parameter.Type: GrantFiled: February 11, 2010Date of Patent: January 7, 2014Assignee: Daniel Measurement and Control, Inc.Inventors: Daniel J. Hackett, III, Charles W. Derr, Graham W. Forbes, Kerry D. Groeschel, Henry C. Straub, Jr.

Patent number: 8302455Abstract: A system and method for calibrating an ultrasonic flow meter. In one embodiment, a method includes disposing a fluid circulating device within a flow meter. Fluid is circulated in the flow meter by operation of the fluid circulating device. An acoustic signal transit time within the flow meter is measured during the circulating. Based on the measuring, a portion of the acoustic signal transit time caused by latency induced by components of the flow meter is determined.Type: GrantFiled: February 11, 2011Date of Patent: November 6, 2012Assignee: Daniel Measurement and Control, Inc.Inventor: Henry C. Straub, Jr.

Patent number: 8181533Abstract: In an embodiment, an ultrasonic flow meter comprises a spool piece including a throughbore and a transducer port extending from the outer surface of the spool piece to the throughbore. In addition, the ultrasonic flow meter comprises a transducer assembly disposed in the transducer port. The transducer assembly has a central axis and comprises a transducer holder having a first end proximal the throughbore of the spool piece, and a second end distal the throughbore of the spool piece. Further, the transducer assembly comprises a piezoelectric capsule including a piezoelectric element. The piezoelectric capsule is coupled to the transducer holder and extends generally axially from the first end of the transducer holder. Still further, the transducer assembly comprises a transformer capsule including a transformer. The transformer capsule is coupled to the transducer holder and is axially spaced apart from the piezoelectric capsule.Type: GrantFiled: January 6, 2010Date of Patent: May 22, 2012Assignee: Daniel Measurement and Control, Inc.Inventors: Charles R. Allen, Henry C. Straub, Jr.
