The Series 534FTB uses Kurz MFTB Technology with the advantages of built-in inlet/outlet piping reducers/expanders and exceptional immunity to upstream/downstream flow disturbances caused by elbows, valves and line size changes. This creative design eliminates the need for field fabrication and assembly of inlet and outlet mating pipe sizes. The Series 534FTB has 8 basic Models covering mass flow ranges to 2350 SCFM and in line sizes from ½” to 8”. This unique design uses special flow nozzles and flow diffusers to obtain flow disturbance immunity without the need for screens, honeycomb or vortex generators and provides extremely low end-to-end pressure drop. Because of this, the output has very low flow noise, exceptional accuracy, repeatability and turn-down ratio.
