The  Alsonic-DSPPL – an ingenious compact portable flow meter ultrasonic model delivers accurate, drift-free liquid measurement.



As a portable transit time flow meter, it uses highly sensitive clamp-on transducers, maintaining non-invasive measurement capabilities for a wide range of applications.

Operating on a high-tech, patented Fine Time measurement technology, the Alsonic-DSPPL  rapidly fires ultrasonic beams, with the prowess to measure pico-second time intervals.

This rapid sequencing produces a precise second phase flow rate measurement even in liquids containing suspended solids or gas bubbles, fortifying its space as a frontrunner portable flow meter ultrasonic model in varied environments.
