Two versions of a new modification of the hydrostatic method for the in-situ measurements of sea-water den-sity are offered. The first version is based on co-processing of the signals of three differential pressure sensors, their inputs being located on three non-orthogonal (a general case) axes. The second version is based on co-processing of the signals of four rigidly connected non-differential pressure sensors. In both cases after co-processing an output signal of the pressure sensor system is insensitive to inclination of the system in the sea environment, which increases accuracy of the in-situ sea water density measurements.
