AUF200 Series

AUF200 Series The 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 270o rotational  Medium temperature up to 105 oC,   T 0-80 oC  Threaded connection, easy for installation  M-BUS communication, easy for remote control and reading  Response time<15 s  SPECIFICATION Measuring Principle: Velocity: Ultrasonic, Time difference W path 0.01-5 m/s Size: Connection: 15 mm, 20 mm, 25 mm, 32 mm, 40 mm Thread Material: Working Pressure: Sensor 25 kgf/cm2 Maximum Stainless Steel 304 Mounting Position: Coupling Supply or Return pipe Brass Displayer: Ball Valve Compact, 270o rotational Brass Ambient Temp.: Display Housing -10~55 oC  PC Ambient Humidity: Turndown Ratio: <=95% RH 50:1-100:1 Power Supply: Accuracy: Battery Power +/-2% Qt-Qmax Battery Life: Repeatability: >6 years (3800 mA) +/-0.3% of reading Record Cycle: Sensor Type: 18 Months PT1000 2 wire, Class B Record Data: Medium Temp.
