Description

The invention relates to the field of measurement technology.

The known method of measuring the volume of solids using a gaseous medium, compressed by an isothermal law, does not provide the specified accuracy and high productivity.

According to the proposed method, the adiabatic compression of the gas in the measuring chamber and the additional chamber separated from it by the membrane is simultaneously produced for increasing the accuracy and productivity, then the gas is held until the temperatures in the chambers and the environment are equal and the subsequent isothermal compression of the gas is carried out using an ilizer that moves in the cylindrical channel communicated with the measuring chamber, to a pressure equal to the pressure in the additional chamber and the magnitude of the displacement of the plunger is judged parameters of.

In the drawing dapa diagram of the device that implements the proposed method.

The device is a camera divided by an elastic partition / into measuring 2 and an additional 3 cameras.

A body, the volume of which is measured, is inserted into the measuring chamber. The camera is equipped with a sensor, triggered.

The equality of pressure in both chambers, and the plumber pair 4.

The piping chamber is equipped with 5 n 6 plunger pairs.

Prnbor works as follows.

The measured body is placed in the measuring chamber at atmospheric pressure and hermetically sealed. Then plunger 7 impregnates the gas compression gas in the accessory chamber for a predetermined amount of volume, as a result of which the back pressure is created in the pump.

At one time, a preliminary compression of the plender chamber was performed by the plunger 8, which pushed the measuring chamber to a constant volume, which was adjusted so that the measuring chamber was created less than before the filling chamber.

Then, within a certain time, SPC1, heat exchange takes place, when the gaseous medium in both chambers gives Teilo through the walls, as a result of which the temperature is equalized to the ambient temperature, and the pressure in the chambers is stabilized.

A subsequent isothermal run through the means of a plunger; er 9 to a certain wellness, or 7, creates a pressure in the measuring chamber that is equal to the pressure in the additional chamber, and the sensor is triggered.

The magnitude of I displacement of the plunger serves as a measure of the measured volume of the body.

Subject invention

The method of measuring the volume of hardened bodies by displacing the gas by the test body and the material into the measuring chamber, characterized in that, in order to increase the body production and the accuracy of measurements, it is produced by one gas 1 i adiabatic compression of gas in

the measuring chamber and the additional chamber separated from it by a membrane, then they hold the gas until the temperature in the chambers and the environment is equal, and the subsequent isothermal compression of the gas with monomer in the cylindrical channel connected to the calger gauge to a pressure equal to in the secondary chamber, and the value of the displacement of the illizier is judged on the parameter being measured.
