RCM - Direct Reading Flowmeters RCM - Direct Reading Flowmeters

GENERAL DESCRIPTION


The RCM is a differential pressure direct reading flowmeter, suitable for liquids or gases with low to medium viscosity, low solid content, and compatible with all materials of construction. The RCM is ideal for industrial applications where durability and reliability are important considerations. It is compact, accurate, economical, needs minimal maintenance, and is resistant to damage. In liquid applications of 6 GPM and higher, pulsations snubbers are incorporated into the connecting pressure passages to produce smooth operation in the presence of turbulence.

RCM - Direct Reading Flowmeters A minimum of 10 PSIG back pressure is required for all RCM models.Upstream piping should have a straight run of at least 10 pipe diameters at the meter inlet connection. If valves are required, they should be installed downstream of the flowmeter. Gas flow models 6000 and 9000 are inlet pressure sensitive and must be regulated to a constant user-selected value at the inlet.
