Processing electronics provide flow data acquisition and telemetry for multiphase flow tomographic ultrasonic transceiver arrays. The processing electronics forms pulse drive signals to cause a tomographic pulse sequence to be emitted. Selected ones of an array of the ultrasonic transceivers emit ultrasonic energy in the tomographic pulse sequence for travel through the multiphase flow. The selected transmitting transceiver is isolated while transmitting it, and the remaining the transceivers are enabled to receive measures of the emitted pulse is after travel through the multiphase flow.
