Abstract
The flow rate of a high temperature fluid flowing through a conduit is measured by passing ultrasonic waves through the fluid. The ultrasonic waves are emitted from an emitter located at one side of the conduit and are received by a receiver located at an opposite site thereof. A first spacer is disposed between the receiver and the conduit, and a second spacer is disposed between the emitter and the conduit. The spacers isolate the receiver and emitter from the high temperatures and conduct the ultrasonic waves without changing the frequency thereof. A quick-release clamp clamps the emitter, receiver and spacers together against the conduit.
