Abstract
A waste oil transfer system includes a system controller configured to determine the authorization status of a waste oil transfer request. The system controller requests a current fluid level in a storage tank from a tank level monitor mounted on the storage tank. The tank level monitor is configured to generate current fluid level information and provide that information to the system controller. The system controller determines the available space in the storage tank and compares the available space to the transfer volume to determine if the storage tank can receive the transfer volume. The system controller then activates a pump to initiate the transfer if the system controller determines that the transfer is authorized or denies the transfer.
