APPLICATION

Meters and records the quantity of thermal and cold energy in relation to the volume of water circulating at the site, measured by means of a volumetric meter with pulse transmitter of any type, and by the temperature difference between flow and return measured by the two detectors supplied (separate pockets). Separate heat and cold metering with automatic switching. Measures and records the hot and cold water consumptions meterd by the volumetric meters with pulse transmitters (IET 7383 / 7343).

Forwarding by means of two outputs the measurement of thermal/cold energy and the metering of the relative flow (IET 7183 / 7143).

  • Communication with Telemanagement systems via parallel connection.

Essential accessories:

  • 1 pair pockets or 1 pair pocket holder connectors.
