เนื้อหา


AUF750 Series

AUF750 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
• 4 line LCD display with flowrate, totalizer & signal condition  
 Stores up 64 Day/Month/Year Totalizer daily value  
 Batch control function  
 Wide range velocities of 0.01 ~ +/- 32 m/s  
 Transducers for pipe size from 15 to 6000 mm  
 High accuracy of +/-0.5% of reading  
 Built-in magnet in transducers, no need for steady tool on metal pipe  
 Data logger function, include date, totalizer, signal condition... etc  
 Response time less than 1 second
