Pressuer_fluctuations_fcyu1q.jpg


I have to buy a TDL analyzer where the stream to be analyzed is nitrogen /methanol at 0.4-1 barg at inlet and about 0.1 barg at the outlet as mentioned in the PID below. the gas travels the yellow line . client is worried about pressure fluctuations causing a measurement error. on the right hand side is a datasheet of the flow cell used. How can I ensure constant pressure at the inlet and outlet , can I use a back pressure regulator at the inlet/outlet? problem is also that we are dealing with very low pressures here. Thanks in advance

Hi,

That's true, but we need to condition the sample( heating and filter) so we are housing the sensor in a cabinet.

regards,
