Weight volume measuring device

Abstract

The invention discloses a weight volume measuring device. The device comprises a fixed table board, a mass comparator, a lower suspension scale, a liquid storage container, a weight placing tool and aweight loading unit. The mass comparator is arranged in the center of the fixed table board; and the lower suspension scale is suspended below the mass comparator. The lower suspension scale is arranged in the liquid storage container, the weight placing tool and the weight loading unit are symmetrically and sequentially arranged on the two sides of the liquid storage container respectively, theweight placing tool is fixed to the fixed table board and is used for placing a weight to be measured, and the weight loading unit is used for grabbing and moving the weight to achieve weight measurement. According to the device, the weight is loaded through rail control and front-and-back and up-and-down movement; due to twice positioning of the rail, positioning is more accurate, and weight measurement is more convenient. And the lower suspension mechanism and a bubble removing device are used and thus errors introduced by measurement are reduced and measurement is more accurate.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a weight volume measuring device. Background technique [0002] At present, the measurement of weights mostly adopts the hydrostatic pressure method, that is, the measurement method based on the liquid density, and the volume of the weights is calculated by the buoyancy of the measured weights in the liquid. The use of mass comparators requires high accuracy of weight measurement. There are many factors that affect the measurement accuracy in existing weight volume measurement devices. Loading and weighing are carried out on the weighing pan of measuring instruments in air and solution, but the turntable is prone to shift, resulting in inaccurate weight positioning; the shift of the balance device during weight measurement; the weight is immersed in the solution to bring air bubbles to the measuring weight Many influencing factors such as weight directly affect the accuracy of weight ...
