Rosemount Regulating Orifice Flow Meter
Rosemount orifice flowmeter technology provides * performance with minimal straight pipe requirements. Nowadays, orifice plate measurement technology
Product details
Rosemount orifice flow meters are designed to simplify installation and maximize performance by eliminating the need for impulse piping, special flanges, or pipeline modifications. Self centering mechanism ensures the accuracy of * while improving the entire installation process
The functions of the Rosemount orifice plate include:
- Reduced the number of straight pipe sections, requiring only twice the diameter of the upstream and downstream pipelines respectively
- Provide superior performance with up to+/-0.5% accuracy in the installation of shorter straight pipe sections
- Direct installation function provides * flowmeter solution
- Compared to traditional orifice plate installation, it can save over 50% of costs
