TDI Glovebox Options - Flowmeter | |
FLOWMETER - GENERAL INFORMATION Flowmeters are durable acrylic that will give long-lasting and trouble free operation, with just a few precautions. The flowmeter is to be used to measure air. The unit must be mounted in a vertical position, to assure proper accuracy. When tightening the piping to the flowmeter, the 1/8" vinyl backing plate should be removed from the meter. This will allow access to the fittings and permits the use of a 9/16" wrench on the hex when tightening the piping to the 1/8" FNTP threads. On start-up, open the needle valve slowly to purge any entrapped air/gas. The flow is read at the center of the spherical float. Occasional cleaning may be required if float visibility becomes hampered. Since our flow units have rod guided floats for stability, an octagonal cleaning may be necessary if the ball float does get stuck on this rod. Disassemble flowmeter carefully. Clean the tapered tube with a mild liquid detergent and a soft brush, along with the other parts removed. |

Rinse all parts with clear water only and dry thoroughly. Avoid all strong solvents e.g. benzene, acetone, etc. Reassembly, reversing the above disassembly procedure. A small amount of grease (halocarbon or equivalent) on the "O" rings would help the seal, as well as prolong the life of the "O" ring. CAUTION: These flowmeters are designed for use with non-hazardous gases, at pressures up to 100 PSI and temperatures up to 65°C (150°F). Do not exceed these limits. Use beyond these limits may cause failure which could result in personal injury. | |
