Embodiment 2

[0054] The difference from the first embodiment is that in this embodiment, there are vertical chutes on the inner wall of the carrier. There are eight chutes. The eight chutes are evenly distributed on the side wall of the carrier 1. The chutes are Sliders are slidably connected inside. It also includes a rubber band. The two ends of the rubber band are respectively bonded to the open end of the slider and the carrier 1.

[0055] In this embodiment, the edges of the supporting layer 3 are bonded to eight sliding blocks, and the supporting layer 3 is slidably connected to the carrier 1 through the sliding blocks and sliding grooves.

[0056] Since some solids have holes, if the gas in the solid holes is not squeezed out after being put into the carrier 1, unnecessary errors will occur in the measurement results.

[0057] With the device in this embodiment, when the solid is put into the carrier 1, after the solid falls on the support layer 3, under the action of gravity, the support...

Abstract

The invention belongs to the technical field of solid volume measurement, and provides a volume measurer aiming at the problem that in the prior art, when the change of a liquid level is read, an artificial reading error is easily generated, so that the preciseness of experimental data is insufficient. The volume measurer comprises: an object carrier which is a hollow cylindrical body with a sealed bottom; a liquid level sensor fixed in a carrier and used for detecting the liquid level depth; a display used for receiving and displaying the detection value of the liquid level sensor; and a processor electrically connected with the liquid level sensor and the display, wherein the processor comprises a computing unit and a starting unit, the computing unit is used for calculating the volume of the detected solid, and a volume calculation formula V=(P2-P1)S / [rho]g of the detected solid is stored in the computing unit. Compared with the prior art, the device has the advantages that manual reading errors do not exist, and the problem of insufficient test data preciseness caused by the manual reading errors can be avoided.

Description

Technical field [0001] The invention belongs to the technical field of solid volume measurement, and particularly relates to a volume measuring device. Background technique [0002] In scientific research and actual production, it is often necessary to measure the volume of experimental samples or products. The precise measurement of volume has a direct ruler on the rigor of experimental research and the accuracy of product production. For example, the electrochemical experiments, corrosion experiments, and friction and wear experiments often performed by scientific researchers in the laboratory require accurate measurement of the sample volume. [0003] In the experiment, when measuring the volume of solids, researchers now basically use a measuring cylinder (measuring cup) to measure, put the solid to be measured into a measuring cylinder (measuring cup) filled with liquid, and then pass the measuring cylinder ( Calculate the volume of the solid by changing the height of the liq...
