ScioSense AS6031 SoC for Ultrasonic Flow Meters is an ultrasonic flow converter for the next generations of ultrasonic water and heat meters. The AS6031 is highly integrated and based on the TDC-GP30 platform. It uses the same high-performant frontend for driving the transducers and processing the receive signal to extract the time of flight information. An additional programmable amplifier allows handling weaker receive amplitudes. Additional features for phase-modulated hit identification give even more robustness to the first hit level detection. The integrated low-power CPU can use 4k of NVRAM and 4k of ROM code to do the flow calculation on chip.
