Clamp-on apparatus for measuring a fluid flow that includes a protective sensor housing
First Claim
1. An apparatus for measuring one or more characteristics of a fluid flowing within a pipe, which pipe has a pipe wall and an exterior surface, the apparatus comprising:
- a housing operable to be mounted on the exterior surface of the pipe, which housing has at least one pocket extending between a pipe-side surface and an outer surface, wherein the pipe-side surface mates with the exterior surface of the pipe;
an acoustic couplant disposed within the at least one pocket, between each sensor unit and the exterior surface of the pipe;
a sealant disposed between the exterior surface of the pipe and the pipe-side surface of the housing, which sealant forms a seal around the pocket when the housing is mounted on the exterior surface of the pipe, which seal is operable to prevent acoustic couplant leakage from inside the housing to outside the housing; and
an array of at least two ultrasonic sensor units for transmitting ultrasonic signals through the fluid flow within the pipe and a receiver for receiving such signals, which array is disposed within the at least one pocket.

Abstract
An apparatus for measuring one or more characteristics of a fluid flowing within a pipe is provided. The apparatus includes a housing, sealant, and an array of at least two ultrasonic sensors. The housing is operable to be mounted on the exterior surface of the pipe. The housing has at least one pocket extending between a pipe-side surface and an outer surface. The pipe-side surface mates with the exterior surface of the pipe. The sealant is disposed between the pipe exterior surface and the housing pipe-side surface. The sealant forms a seal around the pocket when the housing is mounted on the exterior surface of the pipe. The array of ultrasonic sensor units are disposed within the at least one pocket. Each sensor unit includes a transmitter and a receiver. The transmitters are operable to transmit ultrasonic signals through the fluid flow within the pipe. The receivers are operable to receive signals from the transmitters.
