Abstract: A wireless consumption meter, such as an ultrasonic flow meter, and a test and calibration system; the wireless consumption meter including a test mode which changes the wireless communication parameters to transmit less data, with less power, faster and more often, than in a normal operating mode. The test and calibration system includes test boxes arranged to receive measurement data from the consumption meters under the test mode circumstances and a common control unit arranged to control the start and stop of the testing and to establish a test or calibration result based on the received measurements from the consumption meters and by comparing with a reference value from a reference device. Further, methods performed by the consumption meter and the test and calibration system are disclosed.

Abstract: A method of reducing a phase error of a flow rate measurement in an ultrasonic flow meter is disclosed. The flow meter has a flow path for a fluid to be measured, a first ultrasonic transducer having a characteristic quantity and a second ultrasonic transducer having a second characteristic quantity. The method comprises repeatedly measuring the first and second characteristic quantities of the ultrasonic transducers and determining a relation between the characteristic quantities, estimating a phase error value indicative of the phase error from the determined relation between the characteristic quantities, and using the estimated phase error value for correcting a difference between transmission times measured by the ultrasonic flow meter. An output is provided indicative of the flow rate of the fluid in the flow path with reduced phase error from the corrected difference between transmission times.
