RCD Installation Piping Requirements
In order to guarantee accurate readings, the RCD series
must be installed with a minimum of 10 diameters of
straight piping at the inlet and 5 diameters of straight
pipinig at the outlet. This straight piping must be the
same diameter as the fl owmeter fi ttings and should have
no bends, elbows, tees, or valves.
