Abstract

The present invention discloses a liquid density measurement device, comprising a hollow supporter with openings at two ends thereof, wherein the upper end and the lower end of the supporter are connected with upper and lower rigid movable sheets respectively through capsules which are axially-flexible and radially-rigid cylinders, and the supporter, the capsules, the upper movable sheet and the lower movable sheet form a closed hollow cavity, which is internally provided with a rigid rod with two ends thereof connected with the upper movable sheet and the lower movable sheet respectively; and the rigid rod is connected with a stress measurement device. Different pressures are applied to the upper and lower movable sheets when the device is vertically immersed in liquid to be measured, the measured stress of the rigid rod is the pressure difference between the upper movable sheet and the lower movable sheet, thus the density of the liquid can be calculated; the device has simple structure and accurate measurement.

Description
