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.
