Abstract
An ultrasound meter HAS a transmitter, a receiver and a control unit for the transmitter. To improve measurements a feedback connection proceeds between the control unit and the receiver for a signal from the receiver to the control unit, and the control unit regulates energy to the transmitter dependent on the signal fed back from the receiver so that a constant output signal is obtained from the receiver.
