Digital Metal Tube Rotameters

“NRG” Make Metal Variable Area Type Flow Meter are designed to measure flow rate of liquids and gases under

critical conditions. It consists of a tapered metal tube, an indicating assembly and float. A magnet

encapsulated in float couples with rotating magnets are connected to an indicating pointer. Henceforth,

the movement of the float is accurately indicated in terms of flowrate.

They are intended for application where high pressure, temperature or corrosive conditions preclude

the use of conventional glass tube. These are all Metal Variable Area Type Flow meter design to measure

flow rate of Liquids & Gases under critical conditions. It consists of a tapered metal tube, an indicating

assembly and a float. A magnet encapsulates in float couples with rotating magnets connected to an

indicating pointer, thus the movement of the float, is accurately indicated in terms of flow rate.

2. Working Principle

When fluid or gas flows through a taper tube containing a float, a pressure difference of P1 and P2 is

created between upper and lower side of the float. The float moves upwards by a force obtained by

multiplying the pressure differential by the maximum cross-sectional area of the float.
