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.

STANDARD FEATURES :

	Easy to Maintain
	On - Line Installation

	Pipe Size - 40 NB to 300 NB
	For High Flow - 8M / Hr. To 1500M / Hr.
	Two tone powder coated excellent finish
	No threads, No leakage, Avoids corrossions
	Rangeability - 1:10 ,	2 : 10
	Heavy duty design with maximum visibility
	Various options for material of construction of wetted parts
