A direct acting explosion-proof solenoid valve is necessary to regulate the flow rate of a water slurry with volume % of solid particles in the 5-10% range at 2-20 gal/min. After the valve the flow rate also needs to be measured and used for better controlling the flow rate via a feedback loop. Propose a control scheme and select hardware and all peripherals to satisfy the control objective. Feel free to assume whatever additional information that you may need and report with all the other assumptions that you are going to make. It is important to explain what explosion- proof stands for how a solenoid valve functions. The sensor and the actuator (the valve) are to be on the same line.
