6.1 Operating principle
The flowmeter operates on the float measuring principle
The measuring unit consists of a glass cone in which a float can move freely up and down.
The flow goes from bottom to top.
The float changes position so that the lifting force acting on it F1 is in equilibrium with the form
drag F2 and its weight F3: F3 = F1 + F2
The height of the float is read on the scale of the measuring glass and indicates the flow rate.
The top edge of the float marks the reading line for flow values.
