Abstract
A system is presented that monitors the condition of a plurality of pumps in a system of pumps using a remote telemetry unit (RTU) associated with each pump. The RTUs have a sensor configured to detect when a power failure occurs and a power backup system that includes at least one capacitor that is configured to power the RTU in response to a power failure long enough for the RTU to transmit a power failure signal to a computer system that monitors the status of the pumps. The computer system initiates a delay timer in response to receiving a power failure signal and transmits a power failure signal to a technician if a power up signal is not received within the time set by the delay timer. Using capacitors instead of batteries allows the RTU to be sealed within a container and/or a potting compound.
