Orifice Plate (FLC-OP)
Orifice plates are the simplest type of primary flow elements. Their bore diameter
is calculated to generate the specified differential pressure at full scale flow rate.
Suitable orifice plates are available for a wide range of different media.

Orifice Flange (FLC-FL)
For the mounting of orifice plates or flow nozzles, instead of pipe flanges,
special orifice flanges are used. Orifice flanges feature pairs of pressure tappings
which are machined directly into the orifice flange. This has the advantage of
dispensing with any orifice carriers or pressure tappings in the pipe wall.
The assembly of the orifice plate is completed with jacking screws to ensure an
easy removal.

Annular chamber (FLC-AC)
Annular chambers are used to achieve stable measurements under difficult
process conditions. They are mounted between already installed process flanges.
The different pressure in the pipe is compensated for by using a gap located
between the interior of the pipe and the annular chamber.

Special Features of the orifice plate, flange and annular chamber:

  • Max. operating temperature and pressure limited by material and flange
  • Suitable for liquid, gas and steam flow measurement
  • Accuracy ≤ ±0.5 % of actual flow rate
  • Repeatability of measurement of 0.1 %
