For low cost flow measurements with enough upstream and downstream conditions.

For all mediums in industrial sector like power plants, petrochemistry, chemical, paper and cellulose.


•  Accuracy ±0,5% to ±1,2%according to operating data

•  Cheapest flow measurement according to DIN EN ISO 5167

•  Easy installation



The uncertainty will rise with abrasion of the sharp edge from the orifice plate.



Nominal diameter from DN50 – DN1200 / Pressure rating from PN6 – PN600 / Temperature range to 600°

Other dimensions, temperature and pressure ratings also possible on request.



Orifices could be mounted in each position.
