Features
- Directly installed primary element components are easy to install and can be mounted directly between flanges.
- Adopting universal design, it enables reliable and accurate measurement of gas, liquid, and steam flow rates.
- Available for calibers ranging from 15 to 300 mm (0.5 to 12 in.), enabling application flexibility.
- Optional self-centering mechanisms simplify installation.
- Adopts ASME/ISO corner-tap pressure measurement design, compliant with industry standards.
- The unique 4-hole design enables accurate flow measurement even in turbulent conditions.
- The innovative orifice plate requires only two pipe diameters (2D) upstream and downstream, significantly reducing the demand for straight pipe lengths.
- No need for pressure conduits, special flanges, or pipeline modifications—this approach is both economical and highly efficient.
- Can be easily installed directly.
