Abstract: The present invention provides a method for preventing frost damage to one or more flow meters installed in a fluid distribution network containing a fluid, wherein each flow meter is configured to measure a temperature, preferably an air temperature, and to wirelessly transmit the measured temperature, such as via a mobile or a fixed wireless reading system to a processing unit. The method comprises: 1) during a period continuously monitoring (M_TMP) the temperatures measured by the plurality of flow meters over a period of time, 2) performing a data analysis (P_DA) on the temperatures of the plurality of flow meters from the period, 3) based on the data analysis, identifying (I_FDC) one or more ones of the plurality of flow meters as frost damage candidates in a future frost period, and 4) transmitting (T_WS) a warning signal indicative of the frost damage candidates or initiating frost protection measures to protect the frost damage candidates. It has been found that it is possible to monitor temperatures in a no-frost period to identify a frost damage candidate, e.g. if a flow meter is positioned in a pit and the lid is removed thereby causing the risk of a frost damage of the flow meter.
