The Function of Differential Pressure Regulator (DPR) is regulate the pressure drop created due to the differential across the Orifice of the Flow Control Valve. DPR is provided to get stable reading across the rotameter and also to regulate turbulent action of vacuum to manageable level. DPR comes with Chlorinator of capacities of 8 Kgs/hr and above. In smaller capacities the pressure drop is negligible to provide DPR.
