7.1 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
medium flows through the flowmeter from bottom to top.
The float adjusts itself so that the buoyancy force A, acting on it, the form drag W and its weight G
are in equilibrium: G = A + W.
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.
