The Model SL3488D Plus Ultrasonic Flowmeter from SiteLab is a state-of-the-art universal transit-time flowmeter that has been designed using ARM COMA technology and low-voltage broadband pulse transmission. Principally designed for clean liquid applications, the instrument is tolerant of liquids with small amounts of air bubbles or suspended solids found in most industrial environments. Compare with other traditional flowmeters or ultrasonic flowmeters, it has distinctive features such as high precision, high reliability, high capability, and low cost, this versatile flowmeter features other advantages.
With ARM COMA chip, low power consumption, high reliability, anti-jamming and outstanding benefits. It has a user-friendly menu. 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 totaliser with scale factor and 7-digit display. The internally configured batch controller makes batch control convenient. The flow meter ensures a 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.
