Siemens SITRANS F US clamp-on ultrasonic flowmeters 

Product Update - SITRANS FS230: Updated release for gas flow measurement applications 

February 11, 2020


Siemens Digital Industries introduces expanded gas flow measurement capabilities to the SITRANS FS230 clamp-on ultrasonic flow meter. Featuring best-in-class performance and user-friendly operation, the FS230 is now equipped to handle natural, specialty, and process gas as well as well as liquid flow applications.

Available approvals for the SITRANS FS230 include FM (Factory Mutual) Canada, FM US Class 1 Division 2 and equivalent, ATEX, IECEx, or a selectable option code combining all approvals to provide almost complete worldwide coverage.


The SITRANS FS230 flow system consists of the industry-leading SITRANS FST030 digital transmitter paired with Siemens’ extensive and versatile line of SITRANS FSS200 clamp-on ultrasonic sensors. This complete system is suitable for a vast array of industries requiring high-quality liquid and gas flow measurement without disturbing the pipe, such as natural gas and other liquid and gas hydrocarbons, chemical, water and wastewater, HVAC, power, food and beverage, pharmaceutical, mining, and pulp and paper, among others.


Major features and benefits of the SITRANS FS230 include:

  • Market-leading accuracy and repeatability – Accuracy of 0.5% to 1.0% of flow rate for all media/pipe sizes and repeatability of 0.25% according to ISO 11631
  • Available internal AGA 9 gas tables – Simplifying correction for temperature and pressure variations in gas flow 
  • Industry-leading 100 Hz data update rate – Allowing the use of small volume provers for in-situ flow validation by measuring the smallest variations in flow 100 times every second
  • Three resettable totalizers – Allowing simultaneous totalizing for daily, monthly and annual lease production
  • Patented built-in pipe configuration software – Optimizing installation even if the ideal configuration is unavailable
  • Easy to read and use graphic Human Machine Interface – Offers intuitive menu-driven navigation as well as step-by-step setup and troubleshooting wizards, with up to 6 user-configurable views on display at a time
  • SensorFlash®  4MB MicroSD card storage – Certificates, calibration data, sensor parameters and events can be logged every 10ms for easy servicing and record-keeping (can be upgraded to 32GB)
  • Versatile sensors – Require little to no maintenance and can be installed on pipes as small as 0.5 inch and as large as 394 inches (33 ft) without issue


The SITRANS FS230 is now available for configuration, pricing and ordering in the PIA Selector. Lead time will start at 4 to 5 weeks and will decrease quickly to 4 weeks, with further improvement expected over time.


Product selection and ordering

The PIA Selector and PMD have been updated to include the new gas options. The product can be found under the following route: 7ME372. The SITRANS FS230 is available with ordering options for both standard and hydrocarbon derived process values.
