Nova-Tech RITEFLOW FLOWMETERS AND KITS - Manual (Page 9)

Universal millimeter scales permit maximum utilization of a single Flowmeter for a variety of
gases and liquids through the use of flow calibration curves and tables corrected for differences
in specific gravity, pressure and temperature.
The contrasting background is designed to minimize eye fatigue associated with periods of repeti-
tive readings.
Contact Bel-Art for flowcharts for fluids being metered.
PLAIN ENDS
Flowtube should be mounted vertically on a ring stand or other appropriate
support. Input tubing should be connected to the bottom, output tubing to the top.
GUARDED
Guarded Flowmeters utilize a 1 /
8
” wall C.A.B. plastic cylinder to shield the Flowmeter, offering
protection against possible flowtube breakage when being operated under higher pressures (up to
200 max p.s.i.). The Guarded Flowmeter should be mounted vertically on a ring stand or other
appropriate support and input tubing should be connected to the bottom
1 /

” NPT stainless steel
fitting, output tubing to the top one.
MOUNTED
Mounted Flowmeters are designed to enable mounting on an instrument panel or use while stand-
ing on a bench (when mounted on the levelling base). They are available in Aluminum of Teflon
®
models in both 65mm and 150mm sizes for different chemical resistance needs. See
“Specifications” (pages 5 and 6) for complete materials listing. The flowtubes are installed in an
anodized aluminum frame which has a convenient precision needle valve for regulating the flow
through the flowtube. In addition, the frame features an exclusive tubelock design, which facili-
tates simple installation and replacement of tubes in frame by preventing them from turning while
being tightened during assembly.
For use on a bench, use the Levelling Base (cat. no.
H40404-1000). This base contains a level
which
allows adjustment of the Flowmeter to an exactly vertical position, which enhances
accuracy by
eliminating friction between the float and the flowtube.
