Fidicon Devices India is a supplier and manufacturer of variable area flow meters, which are also known as rotameters. Variable area flow meters are used to measure the flow rate of liquids and gases in a pipeline by measuring the differential pressure across a tapered flow tube.

These flow meters are typically made from materials such as glass, metal, or plastic, and are available in a range of sizes and flow ranges. They may also include features such as a built-in flow control valve or a digital readout for easier measurement.

One of the advantages of variable area flow meters is that they are relatively simple and easy to use, with a clear and visible indicator of the flow rate. They are also suitable for a wide range of fluids and can be used in hazardous or corrosive environments.

In addition to variable area flow meters, Fidicon Devices India also offers a range of other flow measurement products, such as flow switches, flow transmitters, and flow meters for specific applications, such as steam or gas.
