<p>Hose reel with a drum (3), driven in an appropriate manner by a motor (11), and provided with a hose 4 through which a medium can flow, which hose (4) is appropriately connected to a tool (7) at one far end provided with a control (8) to operate this tool (7), i.e. to start and to stop it, and whose other far end is appropriately, either directly or indirectly, connected to a supply line (12), characterised in that the hose reel comprises a detection module (9), which comprises a detection body (45), a signal sensor (13) and a processing unit (14), which detection body (45) can detect every flow and/or interruption of the flow of a medium resulting from the operation of the control (8), and can signal or transmit this to the processing unit (14) which can read possible flow pulses or sequences on the basis of a pulse scheme so as to create one or several control signals, for example to produce a start signal for the motorized winding of the hose (4).</p> |
