  • Patent number: 11280141
    Abstract: A technique facilitates monitoring fluid phases of a multiphase flow during, for example, well fluid production operations. According to an embodiment, data may be obtained from devices, such as chokes and pressure sensors. This data is then processed to identify phases of the multiphase well fluid flow. The use of data from such well related devices effectively establishes a virtual multiphase flowmeter. However, the output from the virtual multiphase flowmeter may be calibrated periodically by taking measurements from an actual multiphase flowmeter. In some embodiments, the data from a plurality of flow meters having differing physical operating principles may be correlated in a manner to obtain additional parameters related to the multiphase well fluid flow.

  • Patent number: 8489342
    Abstract: A fluid flow meter estimates the velocity of water or another fluid flowing through pipe by comparing measurements of the water velocity to one or more pre-determined templates. The fluid flow meter may collect measurement signals from one or more flow sensors (e.g., ultrasonic transducers), estimate the fluid velocity or flow rate by comparing the measurement signals to the template(s), and either store the comparison results in local memory, transmit the results to a remote memory or server, or both. In some embodiments, the fluid flow meter transmits the results to a server via a wireless interface (e.g., a Zigbee, Bluetooth, or Wi-fi interface). The transducers and processing system can be powered by a battery, a power line, or, for manifolds installed outdoors, a solar cell. Example transducers and processing systems may also have a passive wake-up feature for power reduction; that is, they may only draw power when water or another fluid flows through the pipe.

  • Patent number: 7836760
    Abstract: The improved monitoring device includes a data acquisition device with an accelerometer inside a bendable tube. One end of the tube is connected to a pole that may be secured to the top of a sewer manhole, while the other end is submerged in a fluid flow. The tilt, oscillations, and pressure exerted upon the tube due to fluid flow are measured and recorded. An improved method includes installing several monitoring devices into sewer system manholes, recording fluid level and flow, reading the recorded data, and displaying the data in chart or map form. Data may be displayed in two or three dimensional maps that may be overlaid with information of topography, street maps, and single or multiple sewer systems. Data displayed on the maps may include fluid flow rates, fluid levels, derivatives and integrals of flow rates, and differences in fluid levels or flow between monitoring devices.

  • Patent number: 7663503
    Abstract: A water meter has a meter register having an encoder having electromagnetic wave emitters, e.g., infrared emitters to measure water flow and direction of water flow through the meter. The encoder has two of three spaced emitters directing infrared rays at predetermined time intervals toward a rotating detector wheel having a reflective surface portion and a non-reflective surface portion facing the emitters and an infrared sensor. The reflective surface portion of the detecting wheel reflects the infrared rays incident thereon toward the sensor. A microprocessor connected to the sensor acts on signals from the sensor to determine material flow. The meter register transmits the signal to a distant receiver. The microprocessor of a meter register has an algorithm to prevent the meter register from sending signals until after the meter register or a water meter having a meter register is installed and water moved through the meter.

  • Patent number: 7624623
    Abstract: An instrument for detecting leaks in a hermetically sealed package. The instrument includes (i) a hollow needle, (ii) a mass flow rate sensor in sealed fluid communication with the lumen defined by the hollow needle, and (iii) a vacuum pump. The vacuum pump is in fluid communication with the lumen defined by the needle for evacuating gas from the hermetically sealed package, and in fluid communication with the mass flow rate sensor for directing mass flow from the evacuated package into operable contact with the mass flow rate sensor so as to permit sensing of any continuing mass flow from the evacuated package. The instrument may further include an oxygen sensor in sealed fluid communication with the lumen defined by the hollow needle for analyzing the oxygen concentration of the gas within the hermetically sealed package.
