Abstract:
1. A method of monitoring a plurality of pumps, comprising: receiving, by a controller from a first sensor in communication with a first pump, a first vibration measurement during a period of time; receiving, by the controller from a second sensor in communication with a second pump, a second vibration measurement during the period of time; based at least in part on the first vibration measurement, determining a first operating condition associated with the first pump, wherein the first operating condition comprises a first threshold associated with the first pump; based at least in part on the second vibration measurement, determining a second operating condition associated with the second pump, wherein the second operating condition comprises a second threshold associated with the second pump; determining that the first pump is in a running operation state if the first vibration measurement is at or above the first threshold and in a stopped operation state if the first vibration measurement is below the first threshold; determining that the second pump is in a running operation state if the second vibration measurement is at or above the second threshold and in a stopped operation state if the second vibration measurement is below the second threshold, wherein the controller is operable to adjust the first operating condition and the second operating condition based on vibration measurements of the first pump and the second pump; and transmitting a control action responsive to the respective operation states of the first pump and the second pump.
