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.

A biphase mark coding transmitter is provided. In the biphase mark coding transmitter, a delay control unit performs equal-interval delay processing on data transmitted by a data coding and protocol processing unit. Then, the current-steering digital-to-analog converter is controlled to charge or discharge a resistance-capacitance circuit to obtain an accurately-controlled conversion time. Data with the controlled conversion time is driven to a CC by a unity-gain buffer to generate an output waveform. The technical solution solves the technical problem of a mutual influence between power source systems of a traditional BMC transmitter which is a digital module and a traditional BMC receiver which is an analog module, and the technical problem of a large noise of a power switch and large consumption of chip area and power which are resulted from digital buffers driven by equal-interval data or clocks in a traditional BMC transmitter.
