SITRANS FS230

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 digitizes the measured signal at the earliest opportunity to transfer it to the FST030 transmitter with optimal EMC protection.

Select and order

For more than 40 years, Siemens has set new standards in clamp-on flow measurement. They key to optimal signal transmission is a harmonious interplay of the ultrasonic sensors and the pipe wall. Lambwave sensors transmit the signal waves in the resonance range of the pipe, our Wide Beam technology achieves an even more accurate adjustment to the application and pipe characteristics. Especially in difficult conditions, such an exact adjustment to flow characteristics is key for highly precise measurements.

SITRANS FS230 with Ex approval is built to meet the toughest demands of the hydrocarbon industry.
