The present invention provides an automated meter station monitoring system for a fluid comprising a processor having algorithms for verifying performance of a fluid flow measurement system. A pressure sensor is operatively connected to the processor to measure the pressure of the fluid. A temperature sensor is operatively connected to the processor to measure the temperature of the fluid. A gas chromatograph is operatively connected to the processor to monitor changes in gas composition and chromatograph response factors of the fluid. An ultrasonic meter is operatively connected to the processor to monitor the velocity of the fluid, speed of sound of the fluid, and meter diagnostics. A flow computer is operatively connected to the processor to record pressure of the fluid, record temperature of the fluid, record gas composition of the fluid, calculate compressibility ratio of the fluid, calculate standard flow rate of the fluid, and calculate energy rate of the fluid.

Ultrasonic meter flow measurement monitoring system

The invention relates to an ultrasonic gas flow meter and corresponding method of verification, where the ultrasonic gas flow meter comprises at least one signal evaluation unit, memory, piping through which gas can flow, and ultrasonic transducers disposed on opposite sides of the piping; the ultrasonic gas flow meter is adapted to detect a flow velocity of the gas flowing through the piping. The method comprises a test procedure for verifying the operation of electronics associated with the ultrasonic gas flow meter wherein, when the test procedure is activated, test signals are triggered which replace the propagation times measured with predefined propagation times associated with an assumed gas flow velocity and the output of the evaluation unit is detected to see how the calculated gas flow velocity compares to the assumed gas flow velocity.

Ultrasonic measurement of flow velocity

The invention relates to a method of measuring a gas flow velocity using an ultrasonic gas flow meter, wherein said ultrasonic gas flow meter includes a horizontal piping through which gas can flow in a flow direction and which has a central axis, at least one pair of measurement paths of equal length spaced apart, extending parallel to one another in separate horizontal planes and inclined to said flow direction, wherein each horizontal plane of a pair of measurement paths is vertically offset by an equal predefined distance from said central axis, wherein an ultrasonic transducer is arranged at each end of said measurement path and each ultrasonic transducer is adapted to selectively act as an ultrasonic transmitter and an ultrasonic receiver, the method comprising the steps of measuring a flow velocity of said gas in a measurement path arranged in an upper region of said piping, measuring a flow velocity of said gas in a measurement path arranged in a lower region of said piping and using the results of these two measurements to predict if a liquid is present in said piping during said measurement.

Method and apparatus for measuring a gas flow velocity

An ultrasound measurement apparatus () is set forth for measuring the flow speed of a fluid in a conduit () having a plurality of ultrasonic transducers () pairs of which span between them a plurality of main measurement paths and at least one diagnosis measurement path, and having an evaluation unit () which is made to determine a respective individual measured value for the flow speed from transit times of ultrasound transmitted and received with and against the flow on each measurement path (), to calculate individual measured values of the main measurement paths as a main measured value for the flow speed, to determine a measured diagnosis value from the at least one individual measured value of the diagnosis measured path and to compare the main measured value and the measured diagnosis value with one another. In this respect at least some of the ultrasonic transducers () have widened transmission and reception lobes so that a plurality of ultrasonic transducers () are arranged in their transmission and reception lobes so that, in addition to the primary measurement paths () spanned between two mutually aligned ultrasonic transducers, at least one additional secondary measurement path () is opened as a main measurement path or as a diagnosis measurement path.

Ultrasound measurement of the flow speed of a fluid in a conduit

A method and ultrasonic meter system for determining pipe roughness. At least some of the illustrative embodiments are ultrasonic meters comprising a spool piece that couples within a flow of fluids, and a first transducer pair mechanically mounted to the spool piece and acoustically coupled to the flow of fluids (wherein the first transducer pair comprises an upstream transducer and a downstream transducer in operational relationship to the upstream transducer and defines a first chord there between). The ultrasonic meter is configured to determine diagnostic data based on acoustic signals transmitted between the first transducer pair (wherein the diagnostic data comprises an asymmetry of the flow of fluids in the spool piece, a cross flow of the flow of fluids in the spool piece, and a profile factor of the flow of fluids in the spool piece). The ultrasonic meter is configured to determine changes in the roughness of a pipe mechanically coupled to the ultrasonic meter based on a trend of the diagnostic data (wherein the trend comprises a substantially constant value of about unity for both the asymmetry and the cross flow and a substantially changing value for the profile factor).
