| description | An ultrasound of flow rate meter which uses the phase difference method wherein two ultrasound transducers W1 and W2 are mounted offset but aligned with each other in a tube through which the velocity of flow is to be measured wherein both of the ultrasound transducers are excited in a pulse manner by an oscillator OS2 and wherein receiving amplifiers V1 and V2 are, respectively, associated with the ultrasound transducers W1 and W2. Evaluation devices are connected after amplifier V1 and V2 such that the phase relationship of the signals at the outputs of the receiving amplifiers V1 and V2 is determined during the reception of ultrasound signals. The phase relationship between the signals at the ultrasound transducers is also determined during transmission of ultrasound signals and this phase difference is used as a reference during reception of ultrasound signals. |
