Abstract
A device for measuring the density of a liquid or of a suspension of solids in a liquid comprises a holder of predetermined length, two pressure sensors mounted at one end of the holder and adapted to be submerged so that the two sensors are vertically at predetermined levels apart in the liquid, and a differential pressure transducer also mounted on the holder and coupled to the pressure sensors for providing an output voltage proportional to the pressure differential sensed by the pressure sensors.
