CPC classification number: G01F25/0007 , G01D4/002 , G01D18/00 , G01F1/66 , Y02B90/241 , Y02B90/246 , Y04S20/32 , Y04S20/42
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 battery-powered consumption meter (10) is provided, which comprises a measurement means for measuring a value relating to an accumulated volume of a fluid flowing (41) in a connected fluid pipe system (40) to make up a consumption meter representation of the accumulated volume, and a first communication means (11), which is a wireless two-way communication means arranged for transmitting (14d) the consumption meter representation from the consumption meter (10) to an external device (20) external to the consumption meter (10), and for receiving a communication (14a, 14b, 14c) therefrom, the consumption meter (10) having at least two modes of operation comprising: a normal operation mode, and a calibration mode different from the normal operation mode, wherein in calibration mode the consumption meter (10) is arranged to transmit the consumption meter representation (14d) to the external device (20) in response to a request (14c) therefor from the external device (20). A calibration system (100) and a method of calibration are provided as well, the consumption meter (10), the calibration system (100) and the method of calibration providing energy-saving over the prior art.
