EW7011CF2055C Ultrasonic heatmeter QP2.5, DN20, C5.5, HC, SR, CD

The measuring device is used to record heat energy or cold energy. The main areas of application are supply systems with a central heating or cooling circuit in which only water is used as the energy medium.

• Available as heat meter and combined heat/cold meter
• Radio data transmission by sending AMR- and Walk-by telegrams in C-mode as standard
• Patented, contamination-resistant ultrasonic measurement process
• Flexibility during commissioning by switching the return and supply flow without exchanging the temperature sensors as well as changing the energy unit
• Any installation position, also „overhead“
• Compact design and detachable calculator unit as standard for tight and difficult-to-access installation situations
• Flow sensor in all-metal design with nominal flow Qp 0.6-2.5 m3/h
• Position-independent, high dynamic range up to 1:100 for detection of smallest flow rates
• Optional only with AMR telegrams or AMR extended telegrams (AMR telegram extended by current flow temperature, current return temperature, current volume flow and current output) available for system optimization
• For secure data transmission optionally with AES encryption mode 5 and mode 7 available
• Standard short and static temperature measurement cycle every 12 seconds (with 10 year battery) - ideal for use in central supply facilities
