BLA200 Ring chamber orifice plate

The ring chamber orifice plates type BLA200 are manufactured for installation between flanges according to standard DIN EN ISO 5167 part 2. But measuring sections with orifice plate require relatively long, straight overall lengths of 15 up to 35 x D. The remaining pressure drop is approx. 60 to 70% of the measured differential pressure.

 

The ring chamber orifice plate BLA200 is mostly used to measure the flow of gases, vapors and liquids, occasionally to restrict the flow or to reduce pressure. It can be easily installed directly between pipe flanges and it is especially suitable in big pipes even for subsequent installation to existing pipe systems.

Product features include:

  • Bore diameter d of 1 up to 800 mm
  • Diameters of DN 10 up to DN 1000
  • Straight inlet/outlet: min. 10 x DN/ 5 x DN
  • Connection by flanges
  • Vacuum or overpressure operation
  • Quick response time and good accuracy
  • Very good long-term stability, no moving parts

Type:

The BLA200 Ring chamber orifice plate is manufactured according to the corresponding operating conditions as pinhole aperture, quarter circle nozzle or segmental orifice and it is available in all types of seal and types of measuring edge.

The differential pressure of the measuring orifices is mostly taken as corner taps. In special cases, the differential pressure tapping can be done similar to standard as edge or flange pressure tapping at or in the flange.
