Abstract
Processing electronics provide flow data acquisition and telemetry for multiphase flow tomographic arrays. The processing electronics convert sensed flow condition data obtained by ultrasonic transceiver tomography arrays into a serial digital data to minimize both the number of external feedthroughs and also the bandwidth required for transmission. The processing electronics also sends the full measured waveforms from each of the transceivers in the tomographic arrays.
Claims6
An apparatus for sensing flow measures within a flow conduit to determine conditions of multiphase flow in the conduit, comprising:
- (a) an array of a plurality of ultrasonic transceivers mounted about the periphery of the conduit transmitting and receiving energy for travel through the fluid in the conduit;
- and
- (b) the array of a plurality of ultrasonic transceivers mounted about the periphery of the conduit further receiving energy after travel through the fluid in the conduit;
- (c) an input signal forming circuit causing the transceivers to individually emit ultrasonic energy pulses for travel through the multiphase flow in the conduit;
- (d) an output signal circuit receiving the ultrasonic energy after travel through the multiphase flow and forming digital data signals from the received ultrasonic energy;
- (e) the output signal circuit further transferring the formed digital data signals for processing to determine conditions of multiphase flow in the conduit.
