We are manufacturers & Exporters of Rotameter Unit (Without Tubes).
The Following are Operating Principles of Rotameter Unit (Without Tubes) :
.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.
