Auxiliary device for pumps
An auxiliary device for pumps, comprising a device body which defines a conveyance duct, which can be connected to the delivery of a pump driven by an electric motor, and at least one accommodation portion for an electronic controller which is connected to at least one sensor for detecting at least one operating parameter correlated to the operation of the pump. The electronic controller is functionally connected to a short-range wireless communication unit which can be configured to communicate with to at least one mobile device operated by a user.
1. An auxiliary device for pumps, comprising a device body which defines a conveyance duct, which is configured to be connected to a delivery of a pump driven by an electric motor, and at least one accommodation portion;
an electronic controller which is accommodated in said accommodation portion and which is connected to at least one sensor for detecting at least one operating parameter correlated to an operation of said pump,
a short-range wireless communication unit accommodated in said accommodation portion; and
at least one mobile device operated by a user and configured to communicate with said short-range wireless communication unit;
said electronic controller being configured to drive a semiconductor power switch interposed between said electric motor and an electric power source of said electric motor by means of at least one mobile device operated by a user; and
further comprising, on said device body, authentication means which are adapted to recognize users authorized to operate on said pump.
2. The device according to claim 1 , wherein the at least one sensor comprises a flow rate sensor of a liquid dispensed by said pump.
3. The device according to claim 2 , wherein said flow rate sensor comprises a turbine which is arranged axially in said conveyance duct and a detector of a rotation of said turbine.
4. The device according to claim 3 , wherein said electronic controller is arranged on an electronic board which is accommodated in a compartment defined in said at least one accommodation portion.
5. The device according to claim 4 , wherein said turbine is provided with magnetic means, said detector comprising a transducer which interacts with said magnetic means and is mounted on said electronic board.
6. The device according to claim 4 , wherein said electronic controller is connected to a temperature sensor of said electric motor.
7. The device according to claim 6 , wherein said temperature sensor comprises a signal detector which is arranged on said electronic board and is adapted to read signals arriving from a thermistor associated with said electric motor.
8. The device according to claim 1 , further comprising user interface means which are supported by said device body.
