MOORE CO. MODEL 63DL DIFFERENTIAL TYPE FLOW CONTROL
The 63DL Controller is used in conjunction with an external needle valve to provide constant volume flow rates for
either liquids or gases over a continuously adjustable flow range.
In gas service, the 63D is used when the downstream pressure is constant to provide a constant mass flow rate (i.e.
Constant downstream pressure is not needed for constant volume flow rates (i.e. volume units per time unit; e.g.
CFM). Since liquids are incompressible, if the volume is held constant, then the mass is constant.
