Gas proportioners back pressure compensated - 1

GAS PROPORTIONERS BACK PRESSURE COMPENSATED To blend two or three gases in homogeneous infinitely variable concentrations, directly at the end use point, this Model G gas proportioner is unsurpassed in convenience and economy. Gas proportioners pay for themselves since they eliminate the need for expensive custom blended gas mixtures. They lend flexibility and economy to the utilization of component gas cylinders and “piped-in” supply lines. Another advantage in laboratory investigations is the freedom to reproducibility increase or decrease concentrations during the course of an experiment. The flow rates are not affected by downstream pressure variations as long as back pressures do not approach or exceed the input pressure. Input pressures of up to 200 psig (13.8 bars) can be used; however, customers’ very often find 50 psig (3.45 bars) a convenient setting to work with. design features ✓ Blending of two or three gases with gas proportioners obviates the need for: ✓ ORDERING FIXED GAS MIXTURES. CONTAMINATION FROM REUSABLE GAS CYLINDERS. POTENTIALLY INACCURATE MIXTURES BY GAS SUPPLIERS. ✓ Rib-guided or fluted metering tubes facilitate stable, accurate readings. ✓ OPTIGRADTM scales minimize parallax and eye fatigue. ✓ Interchangeability of flow tubes and floats.

GAS PROPORTIONERS BACK PRESSURE COMPENSATED BUILT-IN VALVES Meters are available with built-in needle valves (CVTM), high precision metering valves (MFVTM) with “non-rising stems”, or with no valves. The higher cost of MFVTM valves is justified whenever high sensitivity control and resolution are desirable particularly in conjunction with metering tubes of very low flow rates. flow tubes ✓ Precision fabricated from heavy walled, shock resistant borosilicate glass. SPECIFICATIONS STANDARD COMPONENT ✓ Bores are uniformly tapered or formed with internal “rib-guides” or flutes. ✓ Floats are...
