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.
