-This simplification can also be used if a tool determines that a mass flow rate is zero or non-negative.
+This simplification (and similar ones) can also be used if a tool determines that a mass flow rate is zero or non-negative.
+It is also possible to generalize this to the case where more than one sensor is connected.
 The suggested implementation results in
 the following equations, and as indicated the last formula can be
 simplified further by using $\dot{m}_3=0$:
