Variable area flowmeter
Type: V31


The measuring element consists of a float and a conical glass measuring tube. If a medium flows from bottom to top through the measuring tube, the float is lifted until a state of equilibrium is reached between the applied buoyancy force and the float weight. The position of the upper edge of the float in the measuring tube serves as a measure of the flow rate and is read on the scale of the measuring tube.

The displayed flow values are only valid for the medium for which the device was calibrated or for a medium with the same data for density and viscosity.
