What to do if the pressure guide tube keeps getting clogged

The pressure guide tube gets clogged at the pressure sampling point within a day or two, and gas backflow is not allowed in this situation – what are some solutions? Is anyone still using pneumatic needle-punches?
Use plug-in double flanges, or single flanges.

You are referring to those in flow meters: orifice plates or V-cone flowmeters, right! This kind of flow meter generally experiences this issue; at the moment, there is no better solution besides back-purging!
It’s very troublesome when the pressure guide pipe gets clogged; maybe we can replace it with a double-flange type if there’s a chance
What is your medium, and is it prone to crystallization? Pressure tap location? Short-pipe pressure tapping or double-flange pressure tapping?
