Ratio Control Instrumentation and Control Engineering

WebThe flow ratio controller incorporates a cascade system and consists of a master water flow sensor sending out a signal which is used to adjust the set value of a slave oil flow controller to the required ratio. The output signal from the oil flow controller is then used to control the oil valve. The signal from the master to the slave can be ... WebThe outer flow rate would be measured and adjusted to achieve the desired ratio control. The flow rate of reactant A is measured and added with appropriate scaling, to the measurement of the flow rate of the B. The controller would react to the resulting input signal by varying the control valve in the reactant B input line.
