SiteLab SL3488D Plus Multi-path Ultrasonic Flow Meter

The Model SL3488D Plus Ultrasonic Flow meter is a state-of-the-art universal transit-time flow meter designed using ARM COMA technology and low voltage broadband pulse transmission. While principally designed for clean liquid applications, the instrument is tolerant of liquids with the small amounts of air bubbles or suspended solids found in most industrial environments. 

Comparing With other traditional flow meter or ultrasonic flow meter, it has distinctive features such as high precision, high reliability, high capability and low cost, the flow meter features other advantages

With ARM COMA chip, low power consumption, high reliability, anti-jamming and outstanding benefits. User-friendly menu designed. Parameters of pipe range, pipe material, pipe wall thickness, output signals, etc can be conveniently entered via the windows. British and Metric measurement units are available. With the TF Card, 512 files can be stored; the time interval can be within 1 second. Parallel operation of positive, negative and net flow totalizer with scale factor and 7 digit display. Internally configured batch controller makes batch control convenient. The flow meter ensures the higher resolution and wider measuring range by the 0.04nS high resolution, high linearity and high stability time measuring circuit and 32 bits digits processing program.
