The Ultrasonic Meter series (USM®) has a wide temperature range with a high degree of accuracy. The remotely mounted register displays total volume and can display a momentary “Real Time” flow. The USM® Series provides a selectable dry contact pulse output. This unit is designed for heating and cooling systems.

Ultrasonic Meter (USM)
The technology used is based on the static measurement of the transit time and offers many benefits:

  • No moving parts
  • Low pressure loss
  • Large metering dynamics
  • Low start flow rate
  • Resistance to suspended particles
  • Customer Selectable: U.S. Gallons or Liters
  • Customer Selectable: Pulse Output
  • 4-20mA output

This meter can handle temperatures from 41⁰F up to 266⁰F and pressure up to 232 psi. The USM® is available in ¾” (USM075) thru 4” (USM400) sizes and includes a low voltage transformer to power the unit. The USM® Series has a long-life expectancy.

The USM® can be installed vertically, horizontally or on an incline. It is important to make sure the line is ALWAYS full of water. The water flowing in the meter must be glycol free.
