RCA / RCD FLOW REGULATORS

The M21 series flowmeters are built to incorporate the RCA and RCD regulators, that
keep a constant flow rate when the operating pressure at the inlet or outlet are not
constant.
In applications for gases, the RCA model is used in installations where inlet pressure is
variable and outlet pressure or counter pressure is constant, while model RCD is used
in installations where the inlet pressure is constant and outlet pressure or counter
pressure is variable.
In liquids, model RCA is the commonly used.
