Glass Tube Rotameter Manufacturer India | FlowBiz Exports

Accurate flow measurement is critical for maintaining safe, efficient, and cost-effective operations in process industries. Whether handling pure water, corrosive chemicals, or hazardous gases, selecting the right flow measurement instrument prevents operational downtime and safeguards your piping infrastructure.

FlowBiz Exports Pvt. Ltd. is a premier glass tube rotameter manufacturer in India, providing high-precision variable area flow meters designed for rigorous industrial applications.

What is a Glass Tube Rotameter?

A glass tube rotameter—also known as a glass tube variable area flow meter—is an instrument that measures the volumetric flow rate of liquids and gases in a closed pipeline.

It consists of a vertically oriented, tapered borosilicate glass tube containing a free-moving internal float. As fluid or gas enters from the bottom of the meter, it pushes the float upward. The float reaches a stable position when the upward drag force of the fluid equals the downward gravitational force of the float. The flow rate is then read directly from the scale calibrated on the glass tube.
