BEL-ART RITEFLOW®FLOWMETERS
Bel-Art Flowmeters feature precision formed glass flowtubes and are available in three formats:
Plain Ends which is a glass flowtube with floats and Teflon® end plugs; Guarded, which has a plastic
safety guard over the flowtube; and Mounted, which has an anodized aluminum frame to hold the
flowtube and facilitate mounting the unit on an instrument panel or use with a base, free-standing
on a lab bench.
PRINCIPLE OF OPERATION
Bel-Art Flowmeters are fabricated from heavy walled, shock resistant, borosilicate glass with permanently fused ceramic scales. Bores are uniformly tapered with internal rib guides. Floats are
retained by Teflon
20:1 by replacing the glass float with stainless steel float or Carboloy (heavy gauge steel) for size
5 (150mm), size 6 (65mm).
Flowmeters must be installed in a vertical position in the line carrying the gas or liquid to be
measured. Gas or liquid enters through the opening at the bottom end, and exits through the
opening at the top end. Upward pressure causes the float to rise. Flow takes place through the
circular area between the float and the inside surface of the Flowmeter. As the float rises, the
flow area increases, due to the tapered bore of the Flowmeter. Dynamic equilibrium results when
the upward force, due to the air or liquid pressure, balances the weight of the float.
The vertical position of the float at equilibrium corresponds exclusively to one flow rate.
This flowrate is obtained by reading the scale etched on the flowtube calibration chart for the
particular fluid.
®
plugs. Useful metering ratios are 10:1 or better. Ratio can be increased to
Flow rates are determined by reading the scale graduation at the center of the spherical float. To
increase the accuracy and reproduction of the metering a vertical locator line is incorporated into
the geometry of the scale graduation.

OPERATION
Flow input should be connected to the bottom of the Flowmeter and output to the top. Insure that
input and output tubings are securely connected; check specifications to determine maximum
pressure ratings of each format (Plain End, Guarded or Mounted). For most accurate readings,
flowtubes should be exactly vertical to prevent friction of floats on flowtube walls.
BEFORE USE
65 MM
Each 65mm Flowmeter is supplied with a glass float (color: black) inside the flowtube. An additional float is supplied in a vial on the side; stainless steel (color: metallic) for Sizes 1-5, Carboloy
(color: metallic, magnetic) for Size 6.
150MM
Each 150mm Flowmeter is supplied with two floats in the tube. Flowmeters are more accurate
when only one float is used, however two floats can be used with Size No.’s 2 to 5 if they are not
too close to each other in the desired range of flow. Always place the heavier (metallic) float on
the bottom and read the float that is closest to or above the middle of the scale. Size #1 can only
be used with one float; one float must be removed before use.
See Cleaning and Changing Floats (Page 11) for proper float removal and handling.
READING A FLOWRATE
To obtain accurate flow readings locate the center of the float and read the scale graduations as
follows:
1. Position your head in front of the Flowmeter, with your eyes level with the float.
2. Move your head horizontally to the left until the contour of the float appears to just touch the
locator line tangentially.
3. The intersection of the locator line with the horizontal graduation at the center of the float
pinpoints the appropriate reading value.
4. The number on the scale corresponds to a flowrate for the given gas or liquid on the
appropriate calibration chart.
7
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 repetitive 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
1
appropriate support and input tubing should be connected to the bottom
/4” 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 standing 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 facilitates 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.
8

The Aluminum model has
/8” polypropylene hose barb fittings which accept input/output tubing
from 5/16” to 3/8” i.d. The Teflon®model has 3/8” o.d. straight glass connectors for input/output
tubing. Input should be connected to the bottom; output tubing to the top.

Mounted Flowmeters are available in Teflon
or Aluminum models in both 65mm and 150mm
sizes.
FLOWMETER KITS
Kits are designed to allow the use of the entire Riteflow®line of 150mm Flowmeters on one
stand for a wide range of flow measuring capability.

/4” dia. Carboloy
in a vial), two support brackets, two mounting rods, two rod clamps, 5 vials for float storage and a
Flowmeter cleaning kit (94040-9026).
DISASSEMBLY AND ASSEMBLY
Each Guarded and Mounted Flowmeter contains a flowtube, which can be removed or replaced
using the following procedure (See Figure 1).
GUARDED FLOWMETER:
1. Unscrew two end bushings.
2. Remove flowtube from plastic guard.
3. Reassemble in the following order:
a. Insert top rubber gasket (P) in upper bushing (M).
b. Screw plastic tube (N) on upper bushing.
c. Insert flowtube (B) into plastic tube until top of Flowmeter seats against rubber gasket.
d. Insert rubber gasket (P) into lower bushing (M).
e. Screw lower bushing (M) into plastic tube until lower end of the Flowmeter seats against
rubber gaskets.
f. Plastic tube will almost completely cover the thread on bushings and provide a tight seal
against the inner rubber gasket.
9
g. Meter may be directly piped into a
system, or hose ends may be used for
connection with rubber tubing. For quick
disconnect, use Bel-Art’s Stat-O-Lok
tem (19723-0802/0202,
19724-0804/0204)
MOUNTED FLOWMETER:
1. Remove front panel by unscrewing four sock-
et head screws.
2. Remove back panel by unscrewing the two
large nuts. These nuts also hold the support
brackets against the back panel, and these
brackets will also have to be removed. If
Flowmeter is panel mounted, this step can
be omitted.
3. Turn knurled nut on top counter-clockwise as
far as it will go. If it sticks, a pin may be
inserted in the hole in the nut to start it.
4. Push flowtube up and swing it out bottom
first.
5. To reassemble, reverse the above order. Be
sure the scale is facing out.
MOUNTED FLOWMETER:
(ALUMINUM MODELS)
1. Remove front panel by unscrewing four sock-
et head screws.
2. Remove back panel by unscrewing the two
large nuts. These nuts also hold the support
brackets against the back panel, and these brackets will also have to be removed. If Flowmeter
is panel mounted, this step can be omitted.
3. Insert a 5/32” hex wrench into the pressure nut at the top of the flowmeter. While holding the
flowtube between your thumb and forefinger, turn the wrench, counter clockwise to release the
flowtube. Carefully remove the
flowtube so as not to damage it.
4. To reassemble, reverse the above order. Be sure the scale is facing out.

CLEANING AND CHANGING FLOATS
See below for details on Bel-Art’s Flowmeter Cleaning Kit (94040-9026).
For thorough cleaning, floats and float stops should be removed using the following procedures:
For Size Nos. 1, 2 and 3, push bottom float stop upward using the small diameter rod provided.
Push until both stops and floats pop out at the top. Be careful not to scratch inside of flowtube.
For Size.Nos. 4 and 5, pull float stops out from each end by using the wire hooks provided. Insert
one prong through tube past float stop, hook end on far side of stop and pull.
Clean flowtubes using a thin stiff brush with mild laboratory detergent such as Bel-Art’s Aquet
(Catalog No. F17094-0030). More stubborn stains can be removed from glass parts only by using
Chromerge® (F17089-0000), Bel-Art’s chromic-sulfuric acid concentrate. Rinse and dry flowtube by
blowing clean dry air or Bel-Art’s Blow Hard®, O.S. extra (F17080-0100) through it.
Do not handle floats as that may deposit a film that could cause sticking. Observe the following
procedures:
1. Dump floats from flowtube into a plastic cup or on a lint-free surface.
2. Using tweezers, dip each float into a cleaning solution. Never touch floats with your hand.
3. Dip float into an anti-static agent.
4. Remove and dry using clean dry air. Do not breathe on floats, as moisture impairs the clean sur-
face.
5. Replace floats in flowtubes or into their container.
