What should multi-point pressure extraction using standard orifice plates be called?
Thread Content
Today I encountered a problem in the project: an orifice plate with 3 sets of transmitters. Technically, it should be possible to achieve this, but it’s not clear how to describe it in the specifications. I’d appreciate advice from those with more experience!
Using 3 transmitters for one orifice plate – is it to provide a backup mechanism, or to achieve a wider range? If it’s the former, there’s nothing to say ； If it’s the latter, that’s so troublesome; it’s recommended to choose a flow meter with a wide range ratio.
The original poster meant to say “with 3 valve sets”; the word “valve” was missed by accident
Just add a note in the technical document – indicate how many pressure tapping points and how many sets of pressure valves there are. No matter how many sets are used, it’s still called a standard orifice plate. If you really want to be precise, you can add a few words: \"Redundant orifice plate flow meter\"; that’s totally fine
2003, right. One primary element for 3 tables.
We used this type last year; it’s an interlock instrument for the hydrogen flow rate in a hydrogenation unit, designed by the design institute
