Abstract: The present invention provides a sump pump system, including a sump pump monitor and application. The sump pump system includes a sump pump. Components of the sump pump system are installed in and/or near a sump. The sump collects liquid, such as water, from an inlet pipe. The sump pump is operable to remove water from the sump. The sump pump is fluidly connected to a discharge pipe. The discharge pipe is operable to carry water from the sump pump to a storm sewer or other discharge point.

Abstract: Systems and methods are provided for remotely monitoring liquid lubricant levels for pump equipment. A system includes a reservoir to store lubricant and a lubrication gland to expose a shaft seal of the pump equipment to the lubricant. A feed line and a return line circulate the lubricant between the reservoir and the lubrication gland. A level sensor is configured to measure a fluid level in the reservoir. The level sensor uses a communication interface to transmit fluid level data a monitoring device mounted to the pump equipment. The monitoring device is configured to compare the fluid level data against stored alert thresholds and send, to a provider network, an alert signal when the fluid level data is below an alert threshold. If the fluid level data is not below an alert threshold, the monitoring device stores the fluid level data for periodic reporting.
