WebThis example shows that the variable speed control method is the most effective energy method in pumping applications. The examples discussed were calculated for only one flow rate (70%), while the relative power consumption with different control methods depends on the flow rate. This relationship is shown in Figure 3 (Figure below). Web7 hours ago · A typical control loop, controlling the volume flow rate of a liquid in a pipe by a pneumatically actuated valve, is shown below. The valve upstream pressure is a constant hence there is no disturbance input. The \( \frac{\mathrm{I}}{\mathrm{P}} \) (FY 10 ) is an electrical current to pressure signal converter and
