WebA mass flow controller automatically controls the flow rate of a gas according to a set flow rate sent as an electric signal, without being affected by use conditions or changes in gas pressure. Flow rates can be roughly classified into two types: volumetric flow and mass flow. A volumetric flow measurement is affected by ambient temperature ... WebThe flow controller simply maintains the discharge flow rate at a 1:1 ratio with the (total) ingredient flow rate. In fact, pure feedforward control is a variation of 1:1 ratio control, except that the real process variable (tank level) is neither the wild (total incoming flow) nor the captive variable (discharge flow) in the process. how do i get my att account number

WebThere are many methods of proportioning, but fixed foam systems typically use balanced pressure proportioning equipment. All balanced pressure systems use a modified venturi device called a proportioner or ratio controller. Proportioners are available in a variety of sizes and styles to match required flow ranges and pipe sizes. WebHere in a ratio control system, the process variable of one controller becomes the setpoint for another, such that two process variables remain in constant proportion (ratio) to one another.
