The AUF750 series ultrasonic flowmeter uses transit time technology to provide non-invasive liquid flow measurement. It has high accuracy of +/-0.5%, measures a wide range of velocities from 0.01-32 m/s, and can be installed on pipes from 15mm to 6000mm. The flowmeter offers data logging, totalizers, 4-20mA output, and RS-232 communication.

1. Transit Time Ultrasonic Flowmeter
Model AUF750 Series
GENERAL
AUF750 series is a fixed mounted, transit-time ultrasonic
Flowmeter, with clamp-on transducers for non-invasive liquid measurement.
Our microprocessor based, user friendly, field programmable flow
measurement technique allows no interruption of the process flow and
has low installation costs.

4 line LCD display with flowrate, totalizer & signal condition
Stores up 64 Day/Month/Year Totalizer daily value
Batch control function
Transducers for pipe size from 15 to 6000 mm
High accuracy of +/-0.5% of reading
Transducers include magnet devise, for installation on metal pipe without
mounting belt
Data logger function, include date, totalizer, signal condition... etc
Response time less than 1 second
