Abstract

An integral fluid measurement system includes a first sensor configured to communicate using a first communication technology, a second sensor configured to communicate using a second communication technology, and a hybrid interface unit including a first interface configured to communicate with a first sensor using a first communication technology and a second interface configured to communicate with a second sensor using a second communication technology, where the first and second communication technologies are different from each other and may include electrical, fiber optic, radio frequency, optical pulse, and sonic pulse. The hybrid interface unit may also include a digital signal processor, data bus, and power supply, and may be capable of being disposed on a fluid tank wall.
