Abstract
An integrated densitometer-compensator system for providing a digital indication of the dielectric value and density of a fluid in a tank includes a dielectric capacitive measuring device, a vibrating spool fluid density measuring device, a signal processor, a power supply, and a remote computing device. The signal processor produces a digital signal representing the dielectric value and density of the fluid, and includes a serial driver that transmits the digital signal as a serial word by modulating a carrier signal. An unshielded interface cable transmits the serial word, which can contain a unique identifier, and also provides power to the system. Transmission can be electrically, optically, or wirelessly. The exemplary system measures aviation fuel characteristics in fuel tanks onboard an aircraft.
