The TSPRO Overfill Monitor is an integrated overfill prevention and grounding verification system, developed to increase safety during the loading of liquids into tank trucks. Before the start of operation, the equipment checks the vehicle's grounding conditions. During loading, it monitors the product level and signals the operation status through indicator lights. Upon identifying an unsafe condition, its output relay can send a command to the automation or interlock system, allowing the loading to be blocked or interrupted. The monitor is available in specific configurations for the two main loading methods. In the Top Loading version, it uses an optical sensor and grounding clamp. In the Bottom Loading version, it operates with a coiled cable and API plug, adapting to the different loading structures existing in the facilities. Developed for installation in classified areas, it has an aluminum alloy enclosure, IP65 protection rating, and certification for application in Zone 1, offering safety and reliability for operations with flammable liquids.
