ScioSense AS6040 Ultrasonic Flow Meter for Gas Meters
ScioSense AS6040 Ultrasonic Flow Meter for Gas Meters is a solution dedicated to gas meters and is suitable for water meters as well. The system is made of four major blocks: supervisor, front-end, post-processing, and interface. The supervisor manages all tasks and is the master of the whole system, making the AS6040 autonomous. The front-end integrates a high-voltage driver, an integrated PGA and an offset-stabilized comparator in the receive path, a precision TDC for the time-of-flight measurement, amplitude measurement as well as an RDC unit for temperature measurement.
