Bypass Rotameter

Bypass Rotameter



BY PASS ROTAMETER is also called as INFERENCE type Rotameter. We, CVG manufacture and supply BY PASS ROTAMETER which are useful in chemical process industry and research industries. Our BY PASS ROTAMETER'S are accurate and durable, thus economical. In BY PASS ROTAMETER'S there are two lines , main line and bye pass line. There is an orfice plate in the main pipe line. Because of this differential pressure is created and a little amount of flow passes through the by pass line. By measuring flow from by pass line we can estimate flow through main line.


Standard Features

• Rangeability - 1:10 2 : 10
• Heavy duty design with maximum visibility
• Various options for material of construction of wetted parts

Applications Area :
• Scientific laboratory
• Research centres
• Chemical industries

Technical Specification

Pressure Ratings : 40 Bar
Temperature Ratings : - 200 C to 2500 C
Connections : Flanged OR Screwed
Suitable for larger pipeline of : 50 NB to 450 NB
The Flowrate through the : Rotameters is proportional to the pressure drop across the orifice plate
Available : in SS-316/ SS-304/P.P material
Accuracy : 2% FSD
High & Low : low Switches on request

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.

By Pass Rotameter :- Just Insert Model

As indicated in the name you have to just insert the entire assembly in the pipe line between the two flanges.



By Pass Rotameter :-Site Assembly Model


This is an ecconimical model which consists of
1) Main Orifice Plate
2) Glass Tube Rotameter
3) Range Orifice Plate
