An apparatus and method for monitoring and controlling the flow of fluid along with solid particles is described. The main claim of this invention is in utilization of rack and pinion mechanism for converting the rotary motion, initialized by the stepper motor movements based on the signals received from the sensors into linear motion to a pair of sliding plates for varying the area of opening of the valve. It is also claimed that the selection of material and construction of the apparatus is made in such a way that it caters to easy replacement of sliding plates, resistance to erosive environment, leakproofness of the apparatus, and offers less pressure drop at the down stream of the system.
