Abstract
A variable area flowmeter having a float and having a display unit, the display unit includes a pointer element, the pointer element is connected directly or indirectly to the float such that the pointer element is mechanically deflected by the float during the measuring process. The variable area flowmeter that operates particularly reliably and is flexibly applicable at the same time is achieved in that the display unit comprises at least one bi-stable display which only requires an energy supply in order to modify the displayed representation and/or to restore the representation.
