The ultrasonic signal decays severely and can be easily affected by noise during the propagation in gas.Considering these factors
reciprocal electronic circuits for gas ultrasonic flow meter are designed. Two experiments are carried out to test the reciprocal circuits
including transducers paired experiment and temperature test. It is verified that the reciprocal circuits can improve the measurement accuracy and stability for gas ultrasonic flow meter.
