Abstract
A pump monitoring system is provided, the pump including a rotor, and stator, the system including a magnetic field sensor to measure a magnetic field generated by a magnet positioned on a rod above the rotor; and a computer system configured to use the magnetic field to determine the rotor position. The magnetic field generated by the magnet can be used to determine characteristics of the pump including slipping and sticking, twist and twist differential, togging and wobble.
Claims25
A system for monitoring a pump comprising a rotor, the system comprising:
- a magnetic field sensor to measure a magnetic field generated by a magnet;
- and
- a computer system configured to use the magnetic field measurements to determine magnetic field readings and determine a Characteristic of the pump, the characteristic comprising at least one of stick or slip;
- differential twist;
- wobble;
- and cogging.
A processor-implemented method of monitoring a pump comprising a rotor, the method comprising:
- measuring a magnetic field generated by a magnet using a magnetic field sensor;
- and using the magnetic field readings to determine a characteristic of the pump, the characteristic comprising at least one of:
- stick or slip;
- differential twist;
- wobble;
- and cogging.
