The invention relates to a method for controlling a homogeneous batch (1) of pressurized fluid cylinders (2) during at least part of the use cycle of said cylinders. According to the invention, each of the cylinders (2) is provided with a valve (3) having an electronic device (4) including at least one sensor (14) for measuring the pressure (P) inside the cylinder (2), a system (44) for storing/acquiring and processing data and an electromagnetic wave transmitter (34), for example using radio frequency, designed for the remote transmission of at least one of the following items of information: the identity of the cylinder (2) and the pressure (P) measured inside said cylinder. The method includes a transmission step in which all of the cylinders (2) in the batch (1) transmit at least one item of information of the same type when they are in the same phase of the use cycle at the same time and a step in which the same-type items of information transmitted by the cylinders are compared for the automatic detection of an anomaly in the batch (1).
