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.

† All dollar amounts on this site are shown in US currency.
Note: Comes complete with correlation table for each tube and instruction sheet.
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, $365 + 70 + 70 + 70 = $575.00 U.S.
