Abstract
A floating roof monitoring system and method. One or more sensors can be disposed atop a liquid storage tank having a floating roof covering liquid stored in the liquid storage tank. Each laser sensor measures the distance between the sensor and the floating roof. One or more liquid level gauges can be deployed, which measure a liquid position of the liquid stored in the liquid storage tank. A computing system communicates electronically with the laser sensor(s) and the liquid level gauge(s) to calculate the difference between the liquid position and the distance between the sensor(s) and the floating roof to determine the exact position of the floating roof and activate an alarm or force a process associated with the liquid storage tank to halt.
