Variable-area flow meters | Choosing the right flow meter
Variable-area flow meters are used to measure the volumetric flow rate of clean, loaded and viscous liquids as well as clean gases. However, we do not recommend using this type of technology for highly viscous liquids or highly loaded liquids. This type of flow meter must be installed vertically, as the fluid flows from the bottom to the top by pushing a shaped float. The height at which the float stabilizes corresponds with the flow rate and allows direct...

How to choose this product
variable-area-flow-meter

A variable area flow meter measures fluid flow rate in a closed tube.

Applications

The simple structure of these devices make them common in numerous branches of industry. They are found in laboratories, as well as in water treatment plants and in chemical industry facilities.

Technologies

Such instruments consist of a tapered tube containing a float. The fluid rises in the tube, lifting the float, whose level depends on the mass flow. The flow rate is read directly on a scale suitable for the fluid in question.

How to choose

Choice will depend on the fluid to be measured, since each meter is calibrated for a particular fluid. Tube diameter, connectors and required accuracy also should be taken into account.
