Abstract

Method for acquiring the number of revolutions per minute N for a pump 100 of the rotary type, operating at a frequency f and having a number of pumping elements n, comprising the steps of:- obtaining a raw pressure signal S1;- normalizing the raw pressure signal S1 obtaining a clean pressure signal S2;- obtaining an average pressure signal M from the clean pressure signal S2;- identifying negative peaks Pn and positive peaks Pp of the clean pressure signal S2;- obtaining a pulse train S3;- normalizing the pulse train S3 for the frequency f and the number of pumping elements n, obtaining the number of revolutions per minute N of the pump 100.Computer program comprising instructions which, when the program is executed by a processing unit U, cause the computer to perform the steps of the acquisition method.Control unit 10 for a pump 100 comprising:a primary module 1, operatively connected to the pump 100, a secondary module 2 communicating with the primary module 1 by means of a communication system 3,wherein the primary module 1 comprises a pressure sensor 11 configured to detect pressure values P of the pump 100 and to transmit a raw pressure signal S1, obtained from the pressure values P, to the secondary module 2, andwherein the secondary module 2 comprises the processing unit U.Pumping system 1000 comprising the pump 100 of the rotary type and the control unit 10.
