SERIES TUF Ultrasonic Energy Meter

Description: The SERIES TUF Ultrasonic Energy Meter is a precision instrument engineered for measuring heating and cooling energy consumption with exceptional accuracy and stability. Leveraging ultrasonic technology, this compact meter integrates a flowmeter and energy calculator into one unit, making it an ideal choice for installation on chillers and boilers.

Features/Benefits:

  • Lower Maintenance Costs: Local parameter display and absence of moving parts reduce maintenance needs.
  • Serial Communication Output: Enables effortless data transfer.
  • Integrated Flow and Temperature Monitoring: Eliminates the requirement for multiple units.

Applications:

  • Heat metering
  • Utilities billing
  • Tenant billing
  • Monitoring of water heating or cooling systems: radiators, fan coils
