Disposable Flow Tube
First Claim
1. A transit time differential acoustic flowmeter having acoustic transducers which are acoustically coupled to the fluid flowing in a flow tube through the wall of the flow tube itself, in which the flow tube is demountable from the flowmeter and can be disconnected from the external circuit delivering and carrying away the fluid the flow of which is to be detected.

23. A flow tube for an acoustic flowmeter, comprising a conduit having a flow passage therethrough for a fluid the flow rate of which is to be measured, acoustic coupling means at each end of the flow tube, and means for retaining the flow tube in acoustic contact with one more acoustic transducers through the said acoustic coupling means.

24. An acoustic flowmeter comprising a flowmeter body having driving and detection circuitry, an elongate flow tube, two acoustic transducers and acoustic coupling means for transferring acoustic energy between the transducers and a fluid within the flow tube, in which the flow tube is separable from the acoustic transducers and releasably mounted on the body of the flowmeter so as to be readily removable for replacement by a like such flow tube.
