dc.description.abstract | In this paper, a fully designed ultrasonic transit time-based gas flow sensor is presented.
The proposed sensor has been optimized in terms of accuracy, sensitivity, and power consumption at
different design stages: mechanical design of the sensor pipe, piezoelectric transducer configuration
and validation over temperature, time of flight detection algorithm, and electronics design. From
the optimization and integration of each design part, the final designed gas flow sensor is based
on the employment of 200 kHz-piezoelectric transducers mounted in a V-configuration and on the
implementation of a cross-correlation algorithm based on the Hilbert Transform for time-of-flight
detection purposes. The proposed sensor has been experimentally validated at different flow rates
and temperatures, and it fully complies with the accuracy specifications required by the European
standard EN14236, placing the proposed design into the state of the art of ultrasonic gas flow sensors
regarding cost, accuracy, and power consumption, the latter of which is crucial for implementing
smart gas meters that are able to autonomously operate as IoT devices by extending their battery life. | es |
