However, in the process of precision measurement, even a small change in the compression of the liquid will have a large impact on the measurement results
The liquid will generate heat when it is compressed. This process is called the thermal effect of compression. The thermal effect of compression causes the temperature of the measurement environment to change, which seriously affects the measurement results of the compressibility coefficient of the liquid.

Description
technical field [0001] The disclosure relates to the field of precision measurement, in particular to a system and method for measuring the ratio of compressibility of liquid under constant entropy and constant temperature conditions. Background technique [0002] The amount of compression of liquid under low pressure is very small, which is usually neglected in hydraulic engineering design. But in the process of precision measurement, even small changes in the compression of the liquid can have a large impact on the measurement results. The compression of the liquid will generate heat, this process is called the thermal effect of compression, and the thermal effect of compression will cause the temperature of the measurement environment to change, thus seriously affecting the measurement results of the compressibility coefficient of the liquid. [0003] The existing technology is to eliminate the heat generated by the compressed liquid through long-term constant temperatur...
