BLS 100 Orifice plate acc. DIN 19206 or ANSI 

Construction

Orifice plate with welded-on handle/spade 
that can be installed directly between flanges 
with smooth sealing or tongue or RTJ faces. 
Available as a sharp edged, rounded or segmental
orifice according to the conditions of use.
It can delivered as single plate or as complete 
Flange Union with Flanges acc. DIN 19214
or Flanges acc. ANSI B 16.36 

Differential-Pressure measurement

Normally taken through the flange blade, 
or in the pipeline at distances a1 and a2 
from the orifice. As these distances have to 
be taken into consideration when using a correction
factor to calculate the orifice, please inform us of the
position selected. The following types are available:

Pressure taps as flange taps (dia. 1) Flanges with smooth sealing surfaces, PN 10 - PN 100 and DN 50- DN 500  acc. DIN 19214 Part 1 or acc. to ANSI B16.36 (orifice flanges). Pressure taps on the pipe (dia. 2) The taps are in the pipeline. T This arrangement should be avoided when D is less than 200, if the distances a1 and a2 are large in proportion to the pipe diameter (max. 0.80).  In this case the correction factor becomes unreliable, and greater deviations in the measurement may occur.   Pressure taps as flange corner taps (dia. 3) This arrangement is almost equivalent to the ISO 15167 corner taps,  and is used where making a hole in the flange blade is not possible,(e.g. at PN 6) and pipe line taps must be avoided.     Pressure taps located to Vena contracta measurement (dia. 4)
