Patent number: 8549908Abstract: A flow body flow meter includes a flow body and a sensor having one or more probes in the flow body. As a wet gas stream enters the flow body, an internal passage imparts angular momentum to the stream to induce a rotating flow. The wet gas stream at least intermittently carries liquid phase particles and the inertia of the denser liquid phase particles separates them from the rotating flow. The probes of the sensor are located in a part of the rotating flow that is free of any liquid phase particles. The internal passage may include an axial swirler and a cylindrical section downstream from the axial swirler. The axial swirler imparts the nonlinear motion to the stream, and tips of the probes are located near a center axis of the cylindrical section so they are free of any liquid phase particles.Type: GrantFiled: June 17, 2010Date of Patent: October 8, 2013Assignee: Los Robles Advertising, Inc.Inventors: Ralph A. Dalla Betta, Daniel R. Kurz, Bruce B. Burton, Ricardo Martinez, Jerome L. Kurz

Patent number: 7752929Abstract: A sampling device and method for use with a conduit for fluid which has at least one sampling nozzle or sample hole. The sample collected is directed to a manifold where an analysis is conducted and flow rates are measured. The sampled fluid is returned to the conduit. The Static Pressure Control System uses a vacuum pump or other device to equalize the static pressures of the sample nozzle collection manifold and the Static Pressure of the Conduit to achieve the mass-velocity and area-weighted average fluid composition and mass flow rate.Type: GrantFiled: June 21, 2006Date of Patent: July 13, 2010Assignee: Los Robles Advertising, Inc.Inventor: Jerome L.

Patent number: 7647843Abstract: A flow switch uses an analog-to-digital converter combined with a multiplexer to measure voltages at one or more points of a measurement circuit and an algorithm within a microcontroller to calculate flow velocity. The measurement circuit has at least one sensor in the fluid stream. The sensor is heated by passing an electric current through the sensor. A second optional upstream sensor is not heated and is at the fluid temperature. The microcontroller then uses the voltage measurements with calibration information and equations based on the desired mode of operation to calculate the flow velocity.Type: GrantFiled: July 15, 2008Date of Patent: January 19, 2010Assignee: Los Robles Advertising, Inc.Inventor: Bruce B.

Patent number: 7509880Abstract: Method and device are provided for accurately measuring fluid flow in a conduit. A fluid flow meter conditioning body, in-line with the conduit, conditions the fluid flow so as to provide a flattened and invariant fluid velocity profile. The device provides high immunity to upstream and downstream non-uniform fluid velocity profiles. Fluid diffusers adapt the device to different conduit sizes, eliminate field welding and conduit fittings. In a preferred embodiment thermal convection mass flow sensors and circuitry are used to further improve the accuracy of the measurement of the fluid flow.Type: GrantFiled: March 4, 2005Date of Patent: March 31, 2009Assignee: Los Robles Advertising, Inc.Inventor: Jerome L.

Patent number: 6465749Abstract: An apparatus and method for weighing particulates in a gas stream has a generally cylindrical tube manufactured from a magnetostrictive material. One end of the tube is anchored to a mounting block, while the other end includes a filter. The gas stream passes through a filter, where particulates are collected. Several alternative filters provide various alternative benefits for varying applications to different sensing applications. Between the two ends of the magnetostrictive tube are electromagnetic drive and pick-up coils which are magnetically coupled to the tube. The drive coils are driven by an electrical current from an electronic control circuit to generate alternating magnetic fields. These alternating fields in turn stimulate ultrasonic oscillations in the magnetostrictive tube, causing the tube to extend and retract along the length. Oscillation is in the longitudinal direction only, resulting in only one mode of operation.Type: GrantFiled: July 7, 2000Date of Patent: October 15, 2002Assignee: Los Robles Advertising, Inc.Inventor: Jerome Leigh Kurz
