Flow Measurement Ultrasonic Clamp-on Brand New




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.



The SITRANS FS220 is a clamp-on ultrasonic flow system consisting of an FST020 transmitter and FSS200 clamp-on sensors.

The transmitter classification FST020 describes a basic clamp-on ultrasonic flowmeter for basic application requirements. 

Based on the same digitalized platform as the FST030 this system provides the same accuracy and similar functions on a lower cost level. 

This system is ideal for water measurement and any application not requiring temperature or viscosity compensation.



  • Easy installation at any time; no production stop, no need to cut pipe or stop flow

  • Minimal maintenance; external sensors do not require periodic cleaning

  • No moving parts to foul or wear. No contact with media

  • No pressure drop or energy loss

  • Wide turn-down ratio, bidirectional and high stability at zero flow conditions

  • Anomaly compensation tool for correction of non-ideal straight pipe runs. Automatic compensation during backflow

  • Optional WideBeam technology ensures highest performance and accuracy

  • Compatible with all previously installed transit time sensors




The SITRANS FS220 can be used for the following application conditions:

  • Pipe sizes from 10 mm to 10 m

  • Pipe materials: ideal for all metals, glass, FRP and most PVC variants; NOT for concrete pipes and special compound pipes

  • Pipe wall thickness from 1 to 35 mm; specials on request up to 65 mm

  • Media temperatures from -40 to 121 °C; universal high temperature sensors for up to 230 °C max.

  • Underground/submerged locations, non-ideal environments, strong pipe vibrations
