  • Patent number: 10570724
    Abstract: A sensing system that includes a cylindrical body including an internal flow channel that channels a first fluid therethrough, and a sampling chamber. The sampling chamber is in flow communication with an ambient environment. A venturi device is coupled within the cylindrical body, and the venturi device includes a high pressure portion and a low pressure portion. The low pressure portion is in flow communication with the sampling chamber. A valve is coupled within the cylindrical body and is positionable in at least a first position. A first flow channel is defined between the internal flow channel and the high pressure portion through the valve. The first flow channel channels the first fluid towards the high pressure portion such that the low pressure portion draws a second fluid into the sampling chamber from the ambient environment. A sensor assembly determines characteristics of the second fluid within the sampling chamber.

  • Patent number: 10222247
    Abstract: A Holographic Multiphase Flowmeter permits reconstructing the type, size and distribution of Objects within a Multiphase Medium by analysis of the ultrasonic energy reflected from these Objects. If this Multiphase Medium is flowing through a pipe into which a preferred mode of ultrasonic energy is injected at a Reference location, and the amplitude of reflections from the current multiphase Objects at that location and the time it took after the last transmission for that reflected signal amplitude to arrive at the Receive transducer are recorded, it is possible to determine the velocity of the medium by measuring the travel time taken for these same Objects to arrive at a known distance downstream by correlating the same type of reflection data at this second Correlation location. Analysis of this data permits displaying type and size of the Objects in a graphic image showing their distribution within the liquid in real time.

  • Patent number: 9080905
    Abstract: A method for operation of several adjacent magnetic-inductive flow meters, each of which has a measurement tube through which an electrically conductive medium flows, a magnetic field generating apparatus for permeating the medium with a magnetic field having a component perpendicular to the longitudinal axis of the measurement tube, and a measurement apparatus for measuring the voltage induced into the medium and for determining the flow rate from the induced voltage. Each flow meter has a control apparatus. In order to prevent variations of mutual influences on the flow rate measurements by the magnetic fields of adjacent flow meters, measured flow rate values from individual measurement processes and synchronous measurement processes are used to determine the mutual influences on the flow rate measurements, and influences that are free of variations are compensated by the magnetic fields of the adjacent flow meters being synchronized.

    Abstract: A fluid flow metering device comprises a ball valve locatable in a fluid flow, having at least two transverse bores through the ball valve, a first transverse bore and a second transverse bore. The first transverse bore includes a fluid flow metering apparatus for measuring the rate of fluid flow through the first transverse bore. The ball valve is preferably rotatable between a first metering position where fluid is flowable through the first transverse bore and a second open position where fluid is flowable through the second transverse bore. In addition, the second transverse bore is dimensioned so that a tool is movable through the second transverse bore when the ball valve is in the second open position.

  • Publication number: 20120011928
    Abstract: A bi-directional fluid flow sensor is disclosed. The sensor comprises a turbine configured to rotate along an axis as a result of fluid flowing past the turbine substantially in the direction of the axis; a magnet mounted to the turbine and configured to rotate with the turbine; and a magnetic flux angle sensor provided adjacent to the turbine and configured to detect the relative flux angle of the magnet as it rotates. The bi-directional fluid flow sensor is sensitive and robust and may be used in a downhole well for example.

  • Publication number: 20110214498
    Abstract: A flow rate device for measuring the flow rate of a fluid flowing through a wellbore is disclosed. The flow rate device includes a differential pressure conduit, a flow restrictor insert and a differential pressure measurement device. The differential pressure conduit is locatable in the wellbore, defines an internal bore, and is adapted to include a restriction having a cross-sectional area to increase the velocity of fluid flowing through the differential pressure conduit to create a differential pressure. The differential pressure conduit defining first and second pressure measuring stations axially spaced along the differential pressure conduit. The flow restrictor insert is located in the restriction to reduce the cross-sectional area of the restriction. The flow restrictor insert defines an internal bore having a cross-sectional area less than the cross-sectional area of the restriction. The flow restrictor insert also has a pressure measuring port aligned with the second pressure measuring station.

  • Publication number: 20110197667
    Abstract: A flow meter to be used in a hole drilled in the bedrock for measuring stream flows in bedrock fractures which are transversal to the hole. The flow meter comprises an elongated body having a cross section which is substantially smaller than the diameter of the hole; separating members placed at a distance from each other in the longitudinal direction of the body for separating the examined section from the other parts of the hole in a substantially pressure-tight manner; dividing members for dividing the examined section into two sectors in the longitudinal direction of the hole; and a flow channel extending through the body and equipped with a flow sensor for measuring the direction and rate of the flow between the sectors. In accordance with the invention, the dividing members are formed of thin and elastic sealing strips, which have been fixed to the body and, being substantially perpendicular to the surface of the body, arranged to surround and delimit the sectors.

  • Publication number: 20110184711
    Abstract: A method for determining permeability of a subsurface formation includes measuring a parameter related to fluid content of the formation at a first time from within a wellbore penetrating the formation. A rate of entry of fluid from the wellbore into the formation is determined from the measurement of the parameter made at the first time. The permeability is determined from the rate of entry.
