Gas sampling and gas conditioning technology 5-6.15ME
6 INTRODUCTION
Optical flow monitoring systems are used for contiuous gas analysis with corrosive sample gases, to
have the possibility of using flowmeters with corrosion resistant floating balls out of e.g. glass.
The optical flow monitoring systems FA1-H-.. are an alternative to the optical flow monitoring systems
FA-1 with light fork barrier. These units can be used in heated gas conditioning systems up to 180°C
also with non metallic or very small floating balls.
7 APPLICATION
The optical flow monitoring unit with light guides is used in gas analysis on heated flowmeters with
temperatures > 60 °C. The measuring cones must be transparent. Thanks to optical scanning, very
low flow quantities can be recorded even in case of flowmeters with non-metallic or very small (1 mm)
floats.
