An economical, compact device for sub-metering applications.

Calculates thermal energy using the signal from a flow sensor installed in a hydronic heating or chilled water system, and the signals from two 10 kΩ temperature thermistors, 100 Ω RTDs or 1000 Ω RTDs installed in the system’s inlet and outlet points.

  • On-board microcontroller and circuitry make precise measurements and produce accurate, drift-free outputs
  • Calibration information for the flow sensor type and pipe size may be preselected or entered by the user in the field
  • Calculates thermal energy using the signal from a flow sensor installed in a hydronic heating or chilled water system
  • Compact cast epoxy body
