  Features
Introducing the Series 534FTB In-Line Thermal Mass Flow Transmitters 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. The Series 534FTB is the newest addition
to the Kurz family of state-of-the-art In-Line Thermal Mass Flow Transmitters for industrial gases. This patented design
eliminates the need for field fabrication and assembly of
inlet and outlet mating pipe sizes. Each Model offers a
choice of three line sizes to meet nearly all applications.
The new Series 534FTB has eight basic Models covering
mass flow ranges to 2350 SCFM, in line sizes from 1/2"
to 8" pipe. This unique design uses special flow nozzles and
flow diffusers to obtain flow disturbance immunity without
the need for screens, honeycomb or vortex generators
providing exceptional low end-to-end pressure drop. Because of this design, the output has very low flow noise, exceptional accuracy,
repeatability and turn-down ratio. The 534FTB meets
CSA (USA and Canada),
IECEx and ATEX Non- Incendive and Explosion- Proof/Flame-Proof Safety Standards and are IP66/NEMA 4X/7 Rated.Kurz is an ISO 9001:2000 Quality Manufacturer.
