BY-PASS ROTAMETER

BY-PASS ROTAMETER
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 lne.
