AUF752 Series

The AUF752 Series is a fixed mounted, transit-time ultrasonic flowmeter. It features clamp-on style transducers for non-invasive measurement of clean homogeneous liquid processes. This user-friendly, microprocessor-based, field-programmable flowmeter ensures that the flow of existing processes can be performed without interrupting the flow and has very low installation costs.

Features

  • 2 lines LCD display with flowrate, totalizer…
  • Stores 720 Hours / 365 Days / 36 Months / 10 Years of Totalizer value
  • Wide range velocities of 0.01 ~ +/-32 m/s
  • Transducers for pipe size from 25-4000 mm
  • High accuracy of +/-0.5% of reading
  • Various output types such as 4-20 mA, pulse, RS485, HART
  • With self-calibration function, real-time measurement calibration
  • Accurate and stable measurement
  • Optional dual channel flowmeter, more accurate and reliable measurement
  • The sensor has anti-high temperature and long service life, it can reach to 200 °C in a short time
