Integral Orifice
Assembly : This type of assembly is used where the
Differential Pressure Transmitter has to be mounted directly
on the Orifice Asssmebly. This eliminates the impulse tubing
from Orifice Assembly to DP Transmitter. This type of
assembly is used for line size below 2” (50 NB). The
transmitter in mounted on the orifice assembly with the help
of 3-Way Manifold.
The assembly consists of orifice plate
with two integral blocks having corner taps. It also
consists of a meter run pipe having length of 750mm on the
upstream side and 250mm on downstream side.
