Abstract
A floating storage tank roof having a roof cover level monitor apparatus uses a flexible rod having a first end in contact with the storage tank cover bottom surface and a second end in contact with a base mounted to the top of the storage tank roof. As the rod flexes the second end of the rod is pushed into a slot within the base and against a resilient member within the slot. Within the slot are disposed proximity switches. As the rod second end sinks into the slot the proximity switches are actuated by mechanical or magnetic means. The spacing of the switches within the slot is calibrated to represent the level of the storage tank roof. A force transducer may also be used in lieu of the switches.
