AtoutFlow-S

Mass flowmeter
for dry solids

The AtoutFlow-S is a state-of-the-art solution for measuring the flowrate of solids.


Atout Process together with Tomoflow Limited has developed a technique for using electrical capacitance tomography to measure multiphase flowrates.

The application to measuring the mass flowrate of dry solids being transported by gravity has been a particular focus.
