Flow Control Overview

One Gun Flow Control Using a Flow Meter in the Mixed Material Line

Fig. 2.7 shows a one gun system that is using a flow meter, installed in the mixed material line, to monitor fluid flow
to the gun. Using a flow meter in the mixed material line, rather than monitoring fluid flow with the component A, B,
and C flow meters, provides a faster response to changes in the flow rate setpoint.
