UTM20 Flow & Energy Meters clamp onto the outside of pipes and do not make contact with the liquid inside the pipe.

The Spirax Sarco UTM20 ultrasonic transit-time flowmeter measures volumetric flow and heating/cooling energy rates in clean liquids as well as those with small amounts of suspended solids or aeration, such as surface water or raw sewage.


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.
