List of Best Glass Tube Rotameters Manufacturing Companies in India
Glass tube rotameters are simple devices that are used for measuring the rate of flow of different liquids and gases. Discover the working principles, applications, and top manufacturers of glass tube rotameters in this blog.
These devices are also referred to as Glass Tube Variable Area Flow Metres. Glass Tube Rotameters are most commonly used for the purpose of in-line and different By-Pass metering applications. These flow-rate measuring devices are made up of tapered borosilicate glass tubes and float. The float moves up and down the tube responding to the fluid’s flow. The scale on the side of the glass tube indicates the position of the float. The flow rate of the fluid or gas is given in units like liters per minute (L/min) or gallons per minute (GPM).

Glass Tube Rotameters: Precise Flow Measurement Solutions
Glass tube rotameters find applications in different industrial settings, laboratories, and other pre-commercial production facilities. The tube used in the device is generally made of borosilicate glass. The float is made of materials like stainless steel, glass, or acrylic. These materials prevent the float from getting corroded. The tube float combination of these devices is an essential component of standardization because it performs the tests. There are lookup tables that can help in transforming the acquired units into the appropriate fluid flow rates. The correlation charts for gasses like nitrogen, oxygen, hydrogen, helium, carbon dioxide, and argon can be used to verify the correlation scales of the rotameter. A link, also known as an end fitting is typically attached to the glass tube rotameters according to the intended use of the device.
If glass tube rotameters are placed at eye level, the scale readings may become simpler to record. Fluids that possess a high pH, and wet steam, are not used with glass tube rotameters. This is because the fluids having a high pH can soften the glass of the tube. The performance of the glass tube is governed by the amount of pressure and temperature limits of the glass tube. The higher temperatures are the main limiting element. Glass tube rotameters can be used where different streams of gas or liquid are mixed or moved. These devices can be suitable for a single fluid being channeled through multiple passages.
Working Principle of Glass Tube Rotameters
A Variable Area Flow Meter or a Glass Tube Rotameter works on the principle of variable area. The principle of a variable area refers to the fluid movement that lifts a float in a tapered tube. The movement of the fluid results in the expansion of the area of fluid passage. The fluid’s buoyancy and velocity in combination raise the height of the float of the device. In the case of gases, the float reacts to changes in velocity head only because the gasses have very little buoyancy. The rate of flow of the fluid or gas is proportional to the annulus (ring-shaped) area. The differential pressure across the annulus remains constant. The Glass Tube Rotameters are made from a tapered borosilicate glass tube. The tube is placed vertically in a frame with the large end in the upward direction and the tiny end facing downwards. The tube consists of a float that is free to move and rests on the stopper at the bottom of the tube. When a fluid flows, the float rises until the fluid’s upward force balances the weight of the float. The float inside the tube rises until it finds equilibrium. The float displays the flow rate in real time when it finds equilibrium. There is a scale next to the float that is used to determine the flow rate of the fluid or gas.
