CF Echo II

Ultrasonic compact heat and cooling meter, qp 0.6-15 m³/h

The CF ECHO II is the compact meter of Itron’s CF Heat and Cooling meter family equipped with an ultrasonic flow meter. Electronic data processing gives high precision throughout the entire measurement curve, producing a large dynamic range.

Flows can be measured from qp 0.6 to qp 15 m3/h (DN15 to DN50) with reliable and stable accuracy.

Thanks to a complete portfolio of body variants of every size, the CF ECHO II meters are very flexible in use. All hydraulic bodies carry a flanked design helping meter installation.

Advanced Functions

The CF ECHO II provides several advanced functions such as data-logging for complex network analysis, double tariff for further billing choices, peak recording, and lots more, which are powerful diagnostic aids for network management.

Communication Device

The plug-and-play communication boards open the way for data collection through various reading systems.

All available data are presented on the highly ergonomic and multifunctional display.
