High-precision Thermal Mass Flow Meters & Mass Flow Controllers for Gases
|Media (real gas calibration)||Air*, O2*, N2, He, Ar, CO2, H2, CH4, C3H8 (other gases and gas mixtures on request)
*O2 & N2 are calibrated with air
|Air/Full scale freely selectable||Body size ¼” from 0 … 25 mln/min to 0 … 60 ln/min (from 0 … 27 SCCM to 0 … 64 SLPM)
Body size ½” from 0 … 60 ln/min to 0 … 450 ln/min (from 0 … 65 SLPM to 0 … 480 SLPM)
The massflow devices offer high accuracy and a wide dynamic range with 2 different instrument versions “Standard” and “Hi-Performance”:
Accuracy up to ± 0.3% of full scale + ±0.5% of reading
Turndown ratio 1 : 100 (extended turndown ratio on request)
Analog & Digital
The mass flow meters and controllers of the red-y smart series make use of the latest MEMS technology and have a digital (Modbus RTU) and analog interface as standard.
Profibus interface is available as option (Profibus DP-V0/DP-V1).
Display includes: Flow rate, totalizer, unit of measure & set point control (controller only)
One meter or controller can be used for up to 10 different gases or gas mixtures
