Patent number: 7430924Abstract: A flow measurement apparatus is provided that combines the functionality of an apparatus that uses strain-based sensors and ultrasonic sensors to measure the speed of sound propagating through a fluid flowing within a pipe, and measure pressures disturbances (e.g. vortical disturbances or eddies) moving with a fluid to determine respective parameters of the flow propagating through a pipe. The apparatus includes a sensing device that includes an array of pressure sensors used to measure the acoustic and convective pressure variations in the flow to determine desired parameters and an ultrasonic meter portion to measure the velocity and volumetric flow of the fluid. In response to an input signal or internal logic, the processor can manually or dynamically switch between the pressure sensors and ultrasonic sensors to measure the parameters of the flow.Type: GrantFiled: June 28, 2007Date of Patent: October 7, 2008Assignee: Expro Meters Inc.Inventors: Daniel L. Gysling, Robert Maron, Christian O'Keefe

Patent number: 7058549Abstract: An apparatus 10 is provided that includes a spatial array of at least two unsteady pressure sensors 18–21 placed at predetermined axial locations x1–xN disposed axially along a pipe 14 for measuring at least one parameter of a fluid 12 flowing in the pipe 14. The pressure sensors 18–21 comprise a plurality of pressure sensing elements such as piezoelectric film sensors 23 for measuring unsteady pressures associated with acoustical pressures and/or vortical disturbances. The sensing elements are disposed circumferentially around the pipe and spaced a predetermined distance. The pressure signals P1(t)–PN(t) provided by the pressure sensors 18–21 are processed by a processing unit to provide an output signal indicative of a parameter of the fluid.Type: GrantFiled: January 21, 2004Date of Patent: June 6, 2006Assignee: C1DRA CorporationInventors: Daniel L. Gysling, Douglas H. Loose, Robert Maron, Thomas Engel, Paul Croteau

Publication number: 20050120799Abstract: A sensor head characterizes unsteady pressures in a fluid flowing within a pipe, as may be caused by one or both of acoustic waves propagating through the fluid within the pipe and/or pressure disturbances that convect with the fluid flowing in the pipe. The sensor head comprises a rigid support structure and at least one transducer attached to the rigid support structure. The rigid support structure holds the transducer in contact with an outer surface of the pipe. The at least one transducer senses relative movement between the outer surface of the pipe and the support structure and provides a signal indicative of unsteady pressures within the fluid at a corresponding axial position of the pipe in response to the relative movement. The support structure may be attached to each transducer in an array of transducers, and may include a handle secured thereto for manipulating the sensor head into contact with the pipe.Type: ApplicationFiled: October 27, 2004Publication date: June 9, 2005Inventors: Daniel Gysling, Thomas Engel, Robert Maron, Paul Croteau

Patent number: 4958517Abstract: Apparatus is presented for measuring weight, torque and side force (bending) on a drill bit for oil and gas well drilling. This apparatus includes radial holes which do not pass completely through the wall of the drill collar sub, but instead, pass only partially through the wall of the drill collar sub. Strain gages are located in the partial radial openings. These strain gages measure each of the three parameters of weight, torque and bending. Each partially formed hole is sealed by a plug and retained in place by a retaining ring. For torque and bending measurements, the strain gages are arranged with symmetry of position between diametrically opposed holes. The strain gages are positioned in an array which departs from symmetry of position to minimize errors in the weight measurement caused by pressure changes in the drilling fluid.Type: GrantFiled: August 7, 1989Date of Patent: September 25, 1990Assignee: Teleco Oilfield Services Inc.Inventor: Robert Maron

Strain gages are located in radial holes in the wall of a drill collar sub for measuring each of the three parameters of weight, torque and bending. The holes are sealed by inner and outer plugs and a ring and bolt structure retains the plugs in place. For torque and bending measurements, the strain gages are arranged with symmetry of position beteween diametrically opposed holes.
