摘要： An ultrasound meter (2) comprising a transmitter (10), a receiver (14) and a control unit (12)for the transmitter (10) is disclosed. In order to improve measurements a feed-back connection (18) is disposed between the control unit (12) and the receiver (14) for a signal from the receiver (14) to the control unit (12) and the control unit (12) is adapted to regulate energy to the transmitter (10) in dependence of the signal fed back from the receiver (14) so that a constant output signal is obtained from the receiver (14).
