Generator Sump Level Monitoring and Automatic Control System with Alarm Features

Abstract

A generator sump tank is a reservoir that holds the lubricating oil for a generator's engine. It acts as a storage space for the oil and allows it to be circulated throughout the engine for lubrication. The sump is typically integrated into the engine's crankcase in wet sump designs. Manual monitoring is often unreliable and can lead to overflow, pump damage, or dry running. This project introduces a microcontroller-based system to automate sump tank monitoring, pump control, and alarm management using level sensor switches and buzzers. The tank is equipped with a level indicator for local monitoring, alongside a dipstick and sensor switches that function as control elements. These level sensor switches send signals to automatically start and stop the pump. Additionally, they provide input to the monitoring and alarm system, enabling indications for pump start/stop status, as well as triggering alarms for low-low and high-high oil level conditions.
