Abstract
The invention relates to an ultrasonic flow meter comprising a flow tube for the fluid whose flow rate is to be determined. The flow meter comprises a transmitting element for emitting ultrasonic waves, which is provided on the outer jacket of the flow tube. A receiving element, which is provided on the outer jacket of the flow tube, is axially spaced from the transmitting element. An influencing element is provided between the transmitting element and the receiving element for influencing the velocity and/or the direction of a portion of the ultrasonic waves.
Claims25
An ultrasonic flow meter comprising a flow tube for a fluid whose flow rate is to be determined, wherein the flow meter comprises a transmitting element for emitting ultrasonic waves which is provided on the outer jacket of the flow tube, a receiving element for the ultrasonic waves which is provided on the outer jacket of the flow tube axially spaced from the transmitting element, characterized in that an influencing element is provided on at least a portion of a part of the flow tube that extends from the transmitting element up to and including the receiving element, which influencing element functions to influence the velocity and/or the direction of at most a portion of the ultrasonic waves.
A method for manufacturing an ultrasonic flow meter comprising the steps of:
- providing an ultrasonic flow meter comprising at least a flow tube, a transmitting element and a receiving element;
- and
- surrounding at least one of the transmitting element, the receiving element or the flow tube with an influencing element for influencing the velocity and/or the direction of at most a portion of the ultrasonic waves.
