20120060944 | METHOD AND APPARATUS FOR MEASURING A GAS 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. | 03-15-2012 |
20120060623 | METHOD OF OPERATING AN ULTRASONIC GAS FLOW METER AND AN ULTRASONIC GAS FLOW METER - The invention relates to a method of operating an ultrasonic gas flow meter, the ultrasonic gas flow meter including at least one signal evaluation unit, at least one memory, a piping through which gas can flow, at least one pair of ultrasonic transducers disposed on opposite sides of the piping and separated by a path inclined to a flow direction of the piping, wherein each ultrasonic transducer is connected to an electronic circuit to selectively act as an ultrasonic transmitter and an ultrasonic receiver, wherein the ultrasonic gas flow meter is adapted to detect a flow velocity of the gas flowing through the piping on the basis of differences between propagation times of ultrasonic signals transmitted and received between each pair of transducers and propagating in opposite directions along the path, wherein the method includes 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. The invention also relates to a corresponding ultrasonic gas flow meter. | 03-15-2012 |
