The SITRANS FS220 digital clamp-on ultrasonic flowmeter provides the most essential flow measurement functionalities with superior accuracy, cost efficiency and ease of use. It is the best-in-class solution for straightforward flow monitoring of liquid processes. The SITRANS FS220 flow system consists of a SITRANS FST020 transmitter paired with SITRANS FSS200 clamp-on ultrasonic sensors, which 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.
