Calibration of flow meters
Calibration of flow meters
(OP)
I calibrate a venturi flow meter at non-standard conditions. I know the calibration is not good at a different location where the barometric pressure and temperature are different. How do I convert the displayed flow rate to actual flow rate? What is the best way around having to convert everytime I use the flow meter.

You can use gas law to do density correction.

You must first get the venturi meter Head Vs Flow curve for different temp. Then only it will be possible for you to caliberate. Hence, this shall be obtained from the flow meter supplier only . Otherwise , no one can help it as the flow meter contant varies from supplier to supplier.
You must specify the medium , location etc. in which flow meter is placed.Then we can provide you specific solutions.
