The issue of not mixing gases and liquids with orifice plate throttling elements
Thread Content
Can a orifice plate flow meter, whose throttling element is used to measure gases, not be used to measure liquid flow? Why? Is it related to the factory design parameters? They all look the same
Sure, that’s possible. . . Who told you it’s not allowed? . . . . . . Go and slap him in the face; I’m here to support you. I’ll even hand you shoes and clubs :P
I heard it from an experienced teacher yesterday; it’s the first time I’ve heard about it too
It’s possible, but it’s not generally used this way. Each orifice plate is determined based on specific process conditions; it’s best to consult the manufacturer
A recalculation is required; direct swapping is not feasible.
The measurement ranges vary depending on the different media, and since the pressures of these media differ as well, the resulting differential pressures also change. Orifice plates are custom-made individually based on the specific conditions of the production process on site; how is it possible to use them in such situations?
I wonder if the original poster is majoring in instrumentation; if so, that would be a real shame! ! The throttling devices and control valves of instruments are all designed specifically for each application, with their specifications determined based on process conditions such as the medium, pressure, temperature, and piping. Not to mention the incompatibility between liquids and gases, even for the same liquid, within the same pipeline but at different pressures or temperatures, the throttling devices will also be different!
