Spirax Sarco UTM-20 Ultrasonic Flowmeter

Blythewood, South Carolina, Dec. 15, 2020 (GLOBE NEWSWIRE) -- Spirax Sarco, the global leader in steam system engineering and management has expanded its product line to include the UTM20 Ultrasonic flowmeter. It is a non-intrusive, clamp-on, ultrasonic meter that measures temperature and fluid velocity to provide Food, Beverage, Oil, Gas, Healthcare, Waste, and Wastewater customers, data about their systems such as energy usage and flow rate. Specifically designed with ease of use and maintenance in mind, the UTM 20 provides helpful diagnostics to reduce guesswork and easily isolate process or application problems. The new Easy Rail Transducers are simple to adjust and optimize on the pipeline for the best possible signal.

"The UTM 20 provides users instantaneous feedback on fluid usage, which enables them to track and report on energy usage and flow rate. It also offers the ability to select up to 8 parameters to log and save for up to 32 days. The UTM 20 is an excellent tool to use for benchmarking to determine the successfulness of initiatives around reducing energy usage and improving process productivity. You cannot manage what you do not measure."

Jennifer Carlino, Steam Plant Essentials Product Manager

According to Carlino, Spirax Sarco's UTM20 Ultrasonic flowmeter features an aluminium enclosure for a long service life in harsh environments, a large, easy-to-read graphical display, and Modbus® communications. The ability to configure and troubleshoot over USB with SoloCUE software is also available.


By clamping onto the outside of pipes, the meters have inherent advantages over other flow meter technologies, including: 

  • Reduced installation time and cost
  • Non-invasive, non-contact measurement
  • Continued operation during installation - no need to shut down the process  
  • No pressure head loss
  • No moving parts to maintain or replace


  • Large, bi-directional flow measuring range
  • Data log up to 8 records
  • Modbus ® RTU or BACnet ® MS/TP over EIA-485; Modbus TCP/IP; BACnet/IP  
  • Configure and troubleshoot over USB with SoloCUE software  
  • Reynolds number, ultrasonic speed and temperature compensation  
  • Large, easy-to-read graphical display
  • Rugged, aluminum enclosure for a long service life in harsh environments


The UTM20 meter is available in a variety of configurations that permit the user to select a meter with features suitable to meet particular application requirements.  

The UTM20 meter is available in two versions:

  • A volumetric flow meter for water, sewage, cooling water, water-glycol mixtures, alcohols and chemicals.
  • A heating/cooling energy flow meter used in conjunction with dual clamp-on RTDs for temperature measurement; ideal for hydronic process and HVAC applications.
