AS6031 Ultrasonic Flow Converter
AS6031 is an ultrasonic flow converter for the next generations of ultrasonic water and heat meters. It is highly integrated and is based on the TDC-GP30 platform. It uses the same high-performant front-end 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.
