This post was last edited by “A Monkey Sitting on a Tree” on January 9, 2017, at 08:00. What exactly are flange pressure tapping, corner pressure tapping, etc.? As a supplementary question, what are the requirements for creating pressure taps?
Orifice plates should be classified into three types: corner connection for pressure measurement (including annular chamber and drilled hole types), flange connection for pressure measurement, and radial distance connection for pressure measurement. When selecting a type, the following information must be provided: 1. Medium being measured 2. Operating temperature 3. Operating pressure 4. Maximum flow rate 5. Common flow rates 6. Inner diameter of the pipe 7. Pipe material 8. Age of the pipeline 9. Requirements regarding pressure loss
The second floor is correct. Orifice plates are classified into corner connection pressure tapping (including annular chamber pressure tapping and drilling pressure tapping), flange pressure tapping, and diameter distance pressure tapping (D-1/2D pressure tapping). The common selection method is: DN
Take a look at the GB/T 2624-2006 series of standards, \"Measurement of fluid flow rate in fully filled pipes using differential pressure devices installed in circular cross-section pipes\".
The original poster’s major is not Instrumentation and Automation; the assessment is complete.
It’s specified in the national standard 2624-2006
