Description

model G multi gas flow meter for low flow rate gas blending and measurement 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 magnifier lens in front shield to enhance reading resolution interchangeability of flowtubes and floats OPTIGRAD™ scales minimize parallax and eye fatigue simple means of panel mounting Description Blending 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 flowrates 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. BUILT-IN VALVES Variable area flow meters (rotameters) are available with built-in needle valves (CV™), high precision metering valves (MFV™) with “non-rising stems”, or with no valves.
