Glass Tube Rotameters Manufacturer
Glass Tube Rotameters for Precise Flow Measurement
Glass Tube Rotameters are designed for general in-line and by-pass metering applications, suitable for both gas and liquid, within the operating limits of glass metering tubes. Operating on the principle of Variable Area, a float moves freely along the tapered borosilicate glass tube with fluid flowing from bottom to top. The float takes a position where the buoyancy forces and float weight are balanced in proportion to the flow rate. The vertical position of the float, indicated by the scale, provides a measure of the instantaneous flow rate.

Handling the glass tube type can be challenging. Vertical mounting is required, and it’s not suitable for pulsating services. Generally, it’s most effective for modest pipe services.
A Rotameter operates by passing a liquid or gas through a tapered tube. To pass through the tube, the gas must elevate a float held inside it.
A rotameter consists of a tapered tube, typically made of glass, with a “float” inside that is pushed up by the flow’s drag force and pulled down by gravity. The “float” may be made of anodized aluminum or ceramic.
Rotameters, also known as variable area flow meters, measure volumetric flow rates of gases or liquids as they pass through the tube’s taper.
It is also known as a variable area flow meter.
No, a Rotameter is a tool used to measure fluid flow rates, not pressure. It is a well-known instrument for gauging a fluid’s volumetric flow.
