SITRANS Clamp-on Flow Meter
SITRANS FS230
The SITRANS FS230 is an ultrasonic clamp-on flowsystem. The SITRANS FST030 transmitter with the proven-in-use FSS200 sensors is ideal for challenging applications and the use in Ex areas. The SITRANS FS230 system is compatible with pipe diameters from DN10 up to DN500. For applications in hazardous areas, the external electronics module SITRANS FS DSL is used. It is installed close to the sensors and digitises the measured signal at the earliest opportunity to transfer it to the FST030 transmitter with optimal EMC protection.
SITRANS FSS200 clamp-on ultrasonic sensors are available in three different versions: WideBeam® (High-Precision), Universal and High-Temperature. The FSS200 sensors feature low maintenance and high precision – even for applications with high levels of aeration or suspended solids.

- Clamp-on flow system for the measurement of liquids, oil or gas
- Designed for use with up to 4 paths
- Designed for use in Ex areas, safe distance to transmitter of up to 150 m
- High accuracy, repeatability and zero flow detection
