AUF790 Series

AUF790 Series is a fixed mounted, Open Channel ultrasonic flowmeter, with clamp-on transducer used for non-invasive 
measurement. Our microprocessor based, user friendly, field programmable flow measurement technique allows no interruption of the process flow 
and has low installation costs.

FEATURES

 ● 4 line LCD display with flowrate, totalizer & Level condition
 ● V-notch, rectangular with and without end contractions, Cipolletti.
 ● Parshall, Palmer-Bowlus, Leopold-Lagco, trapezoidal, H. 
 ● A sampler relay will signal your sampler to collect flow proportion
 ● High accuracy of +/-0.8% of reading
 ● Non-contact flow measurement
 ● Exclusive sensor for open channel flow 
 ● Response time less than 1 second
