METHOD AND SYSTEM FOR DETECTION OF FAULTS IN PUMP ASSEMBLY VIA HANDHELD COMMUNICATION DEVICE
First Claim
1. A method for detecting faults or operational parameters in a pump assembly including an electric motor and a pump by use of a handheld communication device running an app, wherein the pump assembly or electric motor has at least one rotating shaft, the method comprising:
- a) contactless measuring a sound signal emanating from the pump assembly by use of a microphone connected to or implemented in the handheld communication device,b) processing the measured sound signal, andc) recognizing one or more sound emanating conditions including any possible faults by way of the processed sound signal,wherein the handheld communication device provides a feedback, e.g. an audial, visual or vibrational feedback, when an acceptable measurement position of the microphone has been found.
