| description | Apparatus and methods for verifying temperature measurements in an ultrasonic flow meter. In one embodiment, an ultrasonic flow metering system includes a passage for fluid flow, a temperature sensor, and an ultrasonic flow meter. The temperature sensor is disposed to measure temperature of fluid flowing in the passage. The ultrasonic flow meter includes a plurality of pairs of ultrasonic transducers and control electronics. Each pair of transducers is configured to form a chordal path across the passage between the transducers. The control electronics are coupled to the ultrasonic transducers. The control electronics are configured to measure speed of sound between each pair of transducers based on ultrasonic signals passing between the transducers of the pair. The control electronics are also configured to determine, based on the measured speeds of sound, whether a measured temperature value provided by the temperature sensor accurately represents temperature of the fluid flowing in the passage. |
