AUF200 Series measure flow or energy of water running in heating/cooling pipe by temperature sensor based on ultrasonic flowmeter. It's simple, easy to install and battery powered, no need of external power. It can display flow rate, total flow, total heat, total cool, heat power and supply/return temperature etc..

Features:

- Display flow rate, total flow, heating and cooling energy  
- 3.6V battery power, continuous working for 6 years  
- Auto turn off LCD  if no operation within 3 minutes, saving power  
- Supply or return alternatively for mounting   
- Displayer 270^o rotational  
- Medium temperature up to 105 ^oC,  DT 0-80 ^oC  
- Threaded connection, easy for installation  
- M-BUS communication, easy for remote control and reading  
- Response time<15s
