Flow is dependent on the intrinsic properties of the matter itself, such as compressibility, viscosity and density. Example systems are a liquid flowing through a pipe or capillary, air moving ...

which are detected in a third step by highly sensitive quantum sensors through the pipe wall after the fluid has flowed through a defined section. This method can be used to determine the flow ...
