SmartMeasurement's ALSONIC-DPL series is a portable ultrasonic flowmeter with clamp-on transducers for non-invasive liquid flow measurement. The ALSONIC-DPL’s transit-time principle with advanced DSP and Multipulse technology makes it ideal for measuring fluid with higher concentrations of bubbles & suspended solids. . Our microprocessor based, user friendly, field programmable flow measurement technique allows no interruption of the process flow with lower installation costs versus other flowmetering techniques.
- Advanced DSP and Multi-pulse Technology
- Integal 4 line back-lit display combined with a rugged, watertight enclosure
