If a medium with sufficient flow rate flows from bottom to top through a vertically

inserted measuring tube, then the floated element is raised so far, and

the equilibrium between the lift strength of the medium itself and the weight

of the floated element is adjusted. Since the average flow rate is proportional

to the flow quantity per time unit, the determined equilibrium corresponds to

the flow volume. Flow meters with solenoid floated elements can be equipped

with limit value contacts.
