Abstract
A system for circulating a liquid which comprises at least one pump, connectable to at least one pipe for the flow of a liquid and driven by at least one electric motor; sensors being provide for sensing at least two electrical parameters correlated with the operation of the electric motor and a processor which is functionally connected to the sensors and configured to determine, based on the signals provided by the sensors, at least one fluid-dynamic parameter correlated with the flow of the liquid through the pipe.
Claims12
A system for circulating a liquid, which comprises at least one pump, connectable to at least one pipe for a flow of a liquid and driven by at least one electric motor, and further comprising sensing means of at least two electrical parameters correlated with operation of said electric motor and processing means functionally connected to said sensing means and configured to determine, based on signals provided by said sensing means, at least one fluid-dynamic parameter correlated with the flow of said liquid through said pipe.
A method for circulating a liquid, which comprises a step of driving a pump by means of an electric motor in order to make a liquid flow through a pipe, and further comprising the steps of sensing at least two electrical parameters correlated with the operation of said electric motor and of determining, based on a sensed value of said at least two electrical parameters, a value of at least one fluid-dynamic parameter correlated with the flow of said liquid through said pipe.
