Hello..
I am working for a refinery and we are going to change a Flow Differential Pressure Transmitter with an Ultrasonic type Flowmeter in order to achieve a better accuracy because the specific measurement is taken into consideration for the calculation of CO2 emissions of the refinery. My supervisor put me in charge of that replacement. The flowmeter will be installed in a 14" fuel gas line. I searched a bit and what confuses me is the matter of the calibration. It seems that most of these flowmeters must be sent to a laboratory for their calibration. Is there any way of ins-itu calibration? And what about the matter of accuracy? My supervisor wants to "move" to an accuracy of 1%. Can this be done with a two measuring path flowmeter?
Thank you in advance for your time..
