Abstract
A flow measurement system including at least first and second ultrasonic transducers coupled to an existing conduit, a damping material about the conduit between the first and second ultrasonic transducers to prevent crosstalk, a damping material about the conduit upstream of the first ultrasonic transducer to attenuate system background noise travelling in the conduit at large, and a damping material about the conduit downstream of the second ultrasonic transducer to attenuate system background noise travelling in the conduit at large.
Claims41
A flow measurement system comprising:
- at least first and second ultrasonic transducers coupled to an existing conduit;
- a non-metallic pliable damping material about the exterior surface of the existing conduit between the first and second ultrasonic transducers to prevent crosstalk;
- a non-metallic pliable damping material about the exterior surface of the existing conduit upstream of the first ultrasonic transducer to attenuate system background noise travelling in the conduit at large;
- and
- a non-metallic pliable damping material about the exterior surface of the existing conduit downstream of the second ultrasonic transducer to attenuate system background noise travelling in the conduit at large.
