OMEGA® FL-6400A in-line flowmeters are designed
for use with many caustic or corrosive fluids. These
meters feature stainless steel construction, and
because of the unique construction design, they can
be mounted in any position. The FL-6400A flowmeters
have direct-reading scales for water on the
metering tube, and, due to the sharp-edged orifice
float, variances in viscosity have only a minimal effect.
FL-6400A flowmeters feature a unique spring-bound
design flow rate indicator, which can be used with both
clear and opaque liquids for maximum versatility.
Correlation equations for use with other fluids are
available in the user’s manual
