SITRANS FS230 (High Spec) - Clamp-On Ultrasonic Flow Meter


ABLE Instruments offer the SITRANS FS230, which is an ultrasonic clamp-on flow system. 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 DN10.000. 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 FS230 with Ex approval is built to meet the toughest demands of the hydrocarbon industry.
