- Mounting style : Flanges connection according to DIN or ANSI
- Pressure taps : DN 50 and DN 80, 2" and 3"
- Flange facing : Flat or raised face according to DIN 2526 or flat, raised face or ring type joint according to ANSI B 16.5
- Element ratio (H/D) : 0,2, 0,3, 0,4 and 0,5 (0,4 is standard).
Technical Data
- Accuracy : +/- 4-5 % (un-calibrated), +/- 0,5 % (calibrated).
- Repeatability : +/- 0,2 %

- Installation requirement : >5 x D up-stream and >
Advantages
Very suitable for viscous liquids.
Not sensitive to solid particles in the fluid. Bi-directional flow possible.
For very low Reynolds Nos.
Suitable for erosive fluids.
No risk of clogging. Self cleaning.

Accessories
