Differential
pressure ‘P’ is created in the main
Flow by providing an Orifice plate in the main
pipeline.
Because
of this ‘P’ a branch of flow moves through
By-Pass line provided across the orifice plate
from up stream side to down stream side of the
Orifice Plate.
Additional
Range Orifice plate is provided in the By-Pass
line which is designed such that flow through
range Orifice plate flows in proportion with the
flow through main orifice plate.
Hence
by measuring the flow from By Pass line we can
estimate the flow from Main Pipe lne.
