AS6031 is an ultrasonic flow converter based on the TDC-GP30 platform for water and heat meters.
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 to handle weaker receive signals. The split burst enables the detection and correction of a phase jump and gives more robustness to the first hit level detection.
AS6031 provides outstanding low-flow detection capability due to excellent zero-flow drift. The low-power CPU can use 4k of NVRAM & ROM code to do the flow calculation at a few µA current only.
AS6031F1 comes with a flow firmware already on chip, which simplifies the design of ultrasonic water meters and reduces time to market. It covers the whole ultrasonic measurement task so that users have the full flexibility in the choice of the meters central processor and can continue with their existing platforms and software libraries.
The AS6031-DK development kit allows customers a quick and intuitive approach to using the AS6031 UFC in ultrasonic flow meter applications.
