- TL;DR Summary
- I need a highly-accurate method of measuring the diameter or circumference expansion of a pipe undergoing pressurisation.
Ideally, the method should be accurate down to 0.01 millimetres or better.
We're probably talking pipes of up to 150 mm (6") diameter.
Accurately measuring the actual diameter of the pipe is of less importance - it's how much it expands that matters.
My idea is wrapping something around the pipe with an "emitter" and a "sensor" at opposite ends that will be pulled apart as the pipe expands. The sensor can accurately measure its separation from the emitter. The expansion will be so small it can probably be regarded as a simple linear distance.
Is there any reasonably-priced equipment that can be adapted to this purpose?
