ScioSense's AS6031 is an advanced ultrasonic flow converter that builds on the success of the TDC-GP30 platform. Designed for modern water and heat meter applications, the AS6031 provides accurate time-of-flight (ToF) information through a high-performance front-end that drives the transducers and processes the receive signal.
The AS6031 features a programmable gain amplifier that allows it to handle weaker receive amplitudes. Additionally, the system's phase modulation provides further robustness to the first hit level detection. The integrated low-power CPU combines with the precise measurement front-end, enabling outstanding low-flow detection capability down to leakage levels. The AS6031 also offers a variety of data processing options, including SPI with an external microcontroller or an integrated standard pulse interface.
With its ultra-low power consumption, the AS6031 enables battery-operated devices to have years of lifetime. The chip's QFN48 package and integrated features allow for a compact design that minimizes the overall bill of materials (BOM).
The AS6031F1 variant comes with ScioSense's protected flow firmware pre-programmed into the non-volatile memory (NVRAM). These algorithms, along with appropriate calibration and operation parameters, enable the chip to perform complete flow and volume calculation as well as error handling.
In summary, ScioSense's AS6031 is a powerful and efficient ultrasonic flow converter that enables compact designs and minimized BOM for modern water and heat meter applications. Its programmable gain amplifier and phase modulation provide robustness to the system, while its integrated low-power CPU enables precise measurement and complex flow calculation. With outstanding low-flow detection capability, ultra-low power consumption, and versatile data processing options, the AS6031 offers a clear advantage over other ultrasonic flow converters in the market.
