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.
SPECIFICATIONS FLOWTUBES Flowtubes are fabricated from heavy walled, shock resistant, borosilicate glass with permanently fused on ceramic scales. Bores are uniformly tapered with internal rib guides. Floats are retained by Teflon® plugs. Flow ranges are linear; low differential pressures are independent of flow rate changes.
GUARDED Maximum operating pressure: 200 PSIG Maximum operating temperature: 150°F Materials that come in contact with fluids are: Flowtubes: Floats: Borosilicate glass Glass (color: black) and Stainless Steel (color: metallic) with 150mm size 1,2,3,4, and 65mm size 1,2,3,4,5 Glass (color: black) and Carboloy (color: metallic, magnetic) with 150mm size 5 and 65mm size 6 NPT Fittings: Viton-A, 316 Stainless Steel, Teflon® Dimensions: Overall Length: End Bushings: O.D.

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.
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.
The Aluminum model has 1/8” 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.
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™ system (19723-0802/0202, 19724-0804/0204) MOUNTED FLOWMETER: 1. Remove front panel by unscrewing four socket 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.
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.
