An apparatus (100) for controlling the starting and stopping of an electric motor (3) of a motor-driven pump (1), the device (100) comprising: a flow rate detector (101) being configured to be immersed in a fluid and to be movable between a standby position, corresponding to an absence of fluid flow condition, and an operating position, corresponding to the presence of fluid flow condition; a pressure detector (102) configured so as to interact with a fluid and movable between at least two positions depending on a pressure applied by the fluid; a control apparatus (103) configured so as to detect a movement of the flow rate detector (101) and a movement of the pressure detector (102), the control apparatus (103) controlling the starting and stopping of an electric motor (3) of a motor-driven pump (1) depending on the movements detected. The pressure detector (102) is at least partly housed in a chamber (104) made in the flow rate detector (101) in such a way as to form an integrated flow rate and pressure probe (200) housable in a delivery conduit (5a) of a motor-driven pump (1), the chamber (104) being designed to put the pressure detector (102) in fluid communication with said delivery conduit (5a). |
