| Operating Principle |
| |
 |
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 line. |
