The measuring principle
Variable area flowmeters are suitable for the measuring of clean liquids and gases. They consist of upright conical tube made of metal, glass or plastic, in which a sophisticated float moves freely up and down. The flow goes through the tube, which is applied from the bottom to top, causes the float to rise until the forces are in equilibrium.
Three forces are acting on the float:
• The buoyancy force B, which depends on the density of the medium and the volume of the float.
• The gravity force G, which depends on the mass of the float.
• The flow force F which depends on the float shape and the flow velocity through the variable area between float and tube.

Every flow rate corresponds to a defined variable area resulting from the conical shape of the measuring tube and the specific position of the float. With glass cones, the flow value can be read directly from a scale at the level of the float. With metal cones, the float position is transmitted to an indicator by magnetic means. There is no need for auxiliary power. Different measuring ranges are realised through variations in cone sizes and shapes and in selecting different float shapes and materials.

Variable area flowmeters

Typical applications include:
•Measurement and dosing of additives such as catalysts, surfactants, foam and corrosion inhibitors, caustic soda, chlorine or sulphur substances, etc.
• Inerting of tanks or containers
•Measurement and dispensing of rinsing mediums (purge meters)
• Sample feed measurement for analyser systems
•Dosing and monitoring of lubricants and coolants for bearings and seals for process pumps and rotating machinery
•Hygienic applications in the food and pharmaceutical industries
•Measurement of gases and chemicals in laboratories and test facilities
• Gas/oil burner consumption measurement
