Abstract (en)
[origin: WO2016141982A1] The present invention relates to a transceiver circuit for a flow meter comprising a common signal path for signals to be transmitted and/or received via one or more associated transducers, the transceiver circuit comprising a generator circuit, a signal processing circuit and an active circuit, wherein the active circuit comprises a first and a second transistor being operatively connected via their respective emitter terminals thereby forming a combined input/output terminal, said combined input/output terminal being operatively connectable to one or more associated transducers, the active circuit being adapted to act as a buffer for signals to be transmitted, and adapted to act as an amplifier for received signals.
