Abstract:
According to at least one aspect, a fluid flow monitoring system includes an ultrasonic sensor for generating measurement signals associated with respective ultrasonic signals propagating through the fluid in the lumen, a shut-off valve for blocking fluid flow in the lumen, and a controller. The controller can be communicatively coupled to the ultrasonic sensor and to the shut-off valve. The controller can be configured to compute a plurality of fluid flow parameter estimates based on a plurality of measurement signals generated by the ultrasonic sensor over a time window while the shut-off valve is open. The controller can obtain an offset value associated with fluid flow parameter measurements during a zero flow state of the shut-off valve. The controller can then check for presence of a fluid leak event based on the fluid flow parameter estimates over the time window and the offset value.
