PolluCom® C Thermal Energy Meter

Available in these Regions:


Our compact cartridge PolluCom® C thermal energy meter with coaxial connection is used to measure energy consumption in heating or cooling circuits.

The PolluCom® C can also be supplied as a combined heating/cooling meter. You can program the switch-over point between heating and cooling energy metering in this version. This makes plant specification corrections possible, even for already installed meters (e.g., for buildings with concrete core activation).

Benefits to you

  • Reduces costs and assembly work for the adaptation
  • Avoids additional sealing points
  • Is ideally applicable for ”6/12 °C chilling systems” due to temperature range of the flow sensor from 5 to 90 °C
  • Updates measuring values fast (2 seconds for temperatures, 4 seconds for energy and flow rate)
  • Provides password-protected parameter selections on the meter itself without additional peripheral equipment
  • Has a series of factory-fitted, optional modules for electronic meter reading and connection with building automation systems
  • Can be used with water glycol mixtures due to mechanical measuring principle
  • Has a settable correction factor for enthalpy for usage in water glycol systems
