Ultrasonic clamp-on flow and energy meter

Ultrasonic Flow meter clamps outside of pipes, reducing tool fatigue, installation time, material costs.


Spirax Sarco UTMSpirax Sarco, Inc. proudly introduces a new ultrasonic clamp-on flow and energy meter named the UTM10. This unit has the ability to measure liquids with small amounts of suspended solids or aeration in line sizes from ½” to 80 inches. It reportedly provides accurate and repeatable flow measurement readings for full pipe liquid applications such as cooling lines, liquid condensate, water distribution and processes where system shutdown is impossible.

The UTM10 is designed to clamp onto the outside of existing pipes without contacting fluids, reducing installation time and material costs. There is no need to shut down the process for installation or maintenance, therefore the UTM10 can be fully operational in minutes. With no moving parts, there is no mechanical wear; no repair kits or replacement parts are purportedly needed. Future maintenance costs are allegedly virtually non-existent.

The UTM10 features a rugged, compact aluminum enclosure, easy-to-read digital display, bi-directional flow measurement, and a totalized featuring forward, reverse and net total, and Modbus communications. An optional Ethernet connection is available as well as a programming port. USP, a Windows based software utility allows users to easily configure, calibrate, and troubleshoot the UTM with any Windows based PC.

This unit is available in two versions: a stand-alone flow meter and an energy flow meter used in conjunction with dual clamp-on RTDs. The energy flow meter measures energy usage in BTU or Tons and is excellent for chilled water and other HVAC applications.
