AUF761 Series

The AUF761 Series is a fixed-mounted, transit-time ultrasonic Flowmeter. It features factory-mounted transducers that allow it to be flow lab calibrated, reducing or eliminating the random or bias error that can be present in clamp-on style transducer mounting. The meter ensures an accurate, non-invasive measurement of clean homogeneous liquid process, and is widely used in process control and production measurement.

Features

  • 2 lines LCD display with flowrate, totalizer…
  • Stores 720 Hours / 365 Days / 36 Months / 10 Years of Totalizer value
  • Pipe size from DN20-DN1000 mm
  • High accuracy of +/-1% of reading
  • Bidirectional measurement
  • Various output types such as 4-20 mA, pulse, RS485, Alarm
  • With self-calibration function, real-time measurement calibration
  • Accurate and stable measurement
  • The sensor has anti-high temperature and long service life, It can reach to 200 °C in a short time
