how to measure pressure in pipe
(OP)
hi there,
can anyone suggest me to find correct and exact pressure in the pipe. actually i am working on the tube heat exchangers. tubes carry hot gases (burnt flue gases). i want to take reading of pressure and flow rate as well. i used manometre to measure but it increases by time becouse gases are flowing continously inside the tube. i am confused that what reading should be great.

Why does the gas volume increase with time, for instance......

In practical terms, every device has an uncertainty. For example if you have a 0-100 psig digital pressure gauge with +/-0.1% uncertainty, then every reading will be +/-0.1 psig and reporting a reading of 25.1234 psig (like most gauges will) is wrong--the reading is some number between 25.0 and 25.2 psig.
Sorry, but the world we live in doesn't really support "correct and exact" it is more about "good enough".
Now if you would state your problem is engineering terms you might get decent answers.
