Orifice Plate

BLS 100 Orifice Plate DIN 19206

Application
Flow rate measurement of aggressive and non-aggressive media –particularly for large pipelines.

Construction
Orifice plate with welded-on handle/spade for direct installation between flanges with smooth sealing faces. Available as a sharp edged, rounded or quarter circle nozzle according to appropriate conditions of use.

Differential-Pressure Measurement
Normally taken through the flange blade or in the pipeline at distances a1 and a2 from the orifice.
There is a differentiation between pressure taps as flange taps according to DIN 19214 (figure 1) and D-D/2- pressure tapping within the pipe (figure 2) whereas a1 is equivalent to the pipe diameter D and a2 is identical with D/2. In special cases the pressure tapping may occur norm-like as corner tapping in the flange
