Operating principle: The IVA 521 consumption probe operates according to the calorimetric measuring method. The basis of this measuring method is the electrical heating of the mechanically protected built-in sensor. The mass flow, the volume flow and the flow velocity can be measured and determined by the resulting heat flow to the passing medium (gas).
