Variable Area Flowmeters
A variable area flowmeter is used for measuring the flow rates of different fluids, such as liquids, gases, vapor, and so on, in industrial settings. The volumetric flow of a fluid can easily be measured using these flow meters. At Cannon Water Technology, we offer various types of variable area flowmeters from reputed manufacturers like Blue White. The flow meters listed here are specially designed to serve challenging industrial environments and measure the flow rates of fluids with different consistencies and textures, including semi-solids, liquids, particulate fluids, slurries, and so on.
Our competitive prices, world-class customer service, ready-to-ship inventory, and quick turnaround times make us a trusted source for all your flow measurement needs!
How Does a Variable Area Flow Meter Work?
These flow meters feature a conical tube with a float inside it. The fluid flows through the tapered tube and forces the float to position itself such that sufficient area is left for the fluid to pass. This float will rise high when the flow increases. When used to measure the flow rate of liquids, the float rises due to the liquid’s buoyancy and its velocity head. When used for measuring gas flow, this buoyancy can be neglected, and float raises in response to the velocity head. The float of the flow meter moves proportionately to the flow rate of the fluid and the annular area between the tube wall and the float. There comes the point when the upward force of the flowing fluid and gravitational force exerted by the float’s weight downwards equalize. The float will remain constant in this position and won’t move up or down. The flow meter assumes a distinct position with every continuous flow rate. The position of the float will change according to gravity. The flow meters feature in-line floats, but they may also feature pistons or vane. The flow meters must be oriented and mounted vertically to the device for appropriate results. The changed position of the float indicates the flow rate of the fluid under consideration.
Beneficial Features of Variable Area Flowmeters
Our flow meters are popular due to their following beneficial features:
- Many variable area flow meter models feature a linear scale that has an extended measurement range and low-pressure drop.
- These flow meters are made up of high-quality material that makes them ideal for direct sunlight applications.
- We offer a wide range of variable area flowmeters for different types of fluids, including corrosive liquid flow measurement.
- Made of Hastelloy and sturdy materials, our flow meters are proven to assure several years of performance before they are taken out of service.
Applications of Variable Area Flowmeters
