The orifice plate is one of the most common differential producer type flow elements for measuring clean liquids, gases, and low-velocity vapor (steam) flow. The design offers optimum flexibility ideal for applications with many diverse existing piping schemes, and require considerably lower investment for the initial purchase of equipment. The orifice plate also has the advantage of relatively easy and low-cost replacement.
The different types of orifice plates are :
Single Stage Restriction Plate
Multi Stage Restriction Orifice Plate Assembly
Orifice Plates Features
- A low cost, long life with simple and stable structure
- The most common primary element in the world with established standards for manufacture and installation
- Reliable and well understood due to historical flow data
- Easy to use, prove and troubleshoot
Good for most applications in gas, liquid, and steam, including high temperature and pressure applications
