Graphic Multi-Channel Ultrasonic Portable Meter

The SmartMeasurement Alsonic DSPPL is a portable transit-time flow meter with clamp on transducers for non-invasive liquid measurement. This ultrasonic flow meter uses patented Fine Time measurement technology, making use of ultrasonic beams that can measure at pico-second time intervals. This rapid array of measurements enables accurate, drift-free flow rate measurement in liquids that contain a second phase of strained solids or gas bubbles.

The Alsonic DSPPL clamp on flow meter utilizes DSP technology, which enables “cross correlation” of ideal signals to cancel extraneous noise signals and creates a three-dimensional cross section of the velocity distribution profile of the medium flowing through the pipe.

DSP technology also enables the use of FFT (Fast Fourier Transforms) in order to generate the two signals at the same frequency. This increases the signal-to-noise ratio for accurate, drift-free flow measurement in liquids.
