AUF761 Series

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
