Description

To blend two or three gases in homogeneous infinitely variable concentrations, directly at the end use point, these rotameters are unsurpassed in convenience and economy. Gas proportioning rotameters 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 rotameters 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.

Select the desired 150mm flow tube from those listed, delete the FLT-prefix and insert the remaining suffix from the flow tube into the model numbers.

For NIST calibration, add suffix "-NIST AIR" to model number, add $225 per tube, per gas, per float to the price.

Ordering example: FL-5GP-61G-41SA-03C calls out a gas proportioner for three gasses with standard valves and aluminum end fittings with tubes FLT-61G, FLT-41SA, and FLT-03C installed, $394 + 78 + 78 + 78 = $628.00 U.S.
