SITRANS FS220

Description

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 in number of industries, including water and wastewater, HVAC, power and chemical.

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 models: WideBeam® (High-Precision), Universal and High-Temperature.

The FST020 transmitter has been upgraded to deliver leading reliability, user-friendliness and options for customization, while the FSS200 sensors feature low maintenance and high precision – even for applications with high levels of aeration or suspended solids.
