Abstract
The invention relates to an ultrasonic flow measurement system comprising a flow tube for the fluid whose flow rate is to be determined and at least two ultrasound transducer circuitry. At least one of the at least two ultrasound transducer circuitry comprises an ultrasound transmitter that is arranged for transmitting ultrasound signals through said fluid in a transmitting phase, and at least another one of the at least two ultrasound transducer circuitry comprises an ultrasound receiver that is arranged for receiving transmitted ultrasound signals in a receiving phase. The system further comprises at least one receiving circuit that is arranged for reading out the ultrasound receiver in the receiving phase; and control means connected to the at least two ultrasound transducer circuitry and to the at least one receiving circuit. According to the invention, the flow measurement system comprises an ultrasound damping layer provided on the outer jacket of the flow tube, wherein the ultrasound damping layer is provided such that it substantially surrounds the outer jacket of the flow tube and is in contact with both the ultrasound transmitter and the ultrasound receiver. The speed of sound in the material of the flow tube substantially exceeds the speed of sound in the material of the ultrasound damping layer.
