Description

Click on this link if you need more information about Variable Area Flow Meter.

To blend two or three gases in homogeneous infinitely variable concentrations, directly at the end use point, these variable area flow meters are unsurpassed in convenience and economy. Gas proportioning variable area flow meters pay for themselves in a short period of time since their use eliminates the need for expensive custom blended gas mixtures from outside sources. This series of variable area flow meters lend flexibility and economy to the efficient utilization of component gas cylinders and piped in supply lines. Another significant advantage in laboratory use is the freedom to reproducibly increase or decrease concentrations during the course of an experiment.

The flowrates of component gases are not affected by downstream pressure variations as long as back pressures do not exceed or approach the input pressure.
