The precision of a measurement result is improved.

Description

technical field [0001] The invention relates to the technology for measuring the freezing point of petroleum and petroleum products, in particular to a device for measuring the freezing point of crude oil based on ultrasonic technology and a measuring method thereof. Background technique [0002] The freezing point is an important indicator of petroleum products, and the measurement of the freezing point is of great significance to the use, storage and transportation of petroleum products. Condensation point is one of the main basic physical parameters for the design and calculation of petroleum and petroleum product pipeline transportation. The accuracy of its measurement is not only related to the energy saving and consumption reduction of petroleum product storage and transportation, but also an important basis parameter for its flow safety guarantee. [0003] When using the existing petroleum freezing point measuring instrument to measure the freezing point of crude oil,...

AI Technical Summary

Problems solved by technology

There are the following disadvantages in this experiment process: ① During the sample loading process, the sample may hang on the wall, and it will not be easy to tilt the test tube to observe whether the sample is solidified; ② When adding the sample to be tested, the pouring amount cannot be accurately controlled

③ It is necessary to take out the freezing point test tube to the ambient temperature to observe whether the sample is solidified, which increases the thermal history of the oil sample and increases the error of the measurement result

④The experiment is manual operation, and the error of human operation is large
