Abstract

Methods and systems for monitoring the health and operational status of components in a fuel dispensing environment. In one aspect, a method includes providing a control system having a memory in which is stored information representative of a first vibration characteristic of a component, providing a sensor in electronic communication with the control system, the sensor operative to sense vibration characteristics of the component, and coupling the sensor with the component. The method also includes sensing a second vibration characteristic of the component using the sensor, transmitting information representative of the second vibration characteristic to the control system, and comparing the information representative of the second vibration characteristic to the information representative of the first vibration characteristic.
