Device and method for automatically measuring volume of full-automatic oil test sample

Abstract

The invention relates to a device and method for automatically measuring the volume of a full-automatic oil test sample. The device for automatically measuring the volume of the full-automatic oil test sample comprises a signal acquisition unit, a signal processing unit, a measuring pipeline and an electromagnetic valve, wherein the signal acquisition unit and the signal processing unit are a first micro gas pressure sensor (2) and a second micro gas pressure sensor (3); a first flow path (9) / a second flow path (11) are connected with the second micro gas pressure sensor (3) / the first micro gas pressure sensor (2), the first flow path (9) / the second flow path (11) are sample flow paths controlled by an electromagnetic valve (10), and the gas pressure in a pipe changes when the electromagnetic pump sucks the sample. According to the device and method for automatically measuring the volume of the full-automatic oil test sample, the micro gas pressure sensors are adopted, so that contactwith a solution is avoided, leakage and reaction are avoided, and the micro gas pressure sensors have small volume and save space. Combined with a metering pump, the volume measurement of the sample is more accurate.

Description

technical field [0001] The invention relates to the technical field of flowmeters, in particular to a device and method for automatically measuring the volume of a fully automatic oil test sample. Background technique [0002] The use of the flowmeter has the purpose of monitoring. It is to provide the manager or the control system with the accurate value of the flow parameter, so as to make a reasonable judgment and adjustment, achieve excellent control, and improve the quality and output of the product. At the same time, the flowmeter also has an important measurement purpose, using the flowmeter to continuously accumulate the total value for a period of time to provide scientific and reliable fluid total volume or total mass for trade settlement and total volume control. In analytical measurement, there is an inseparable relationship between the amount of a substance and its volume. Flowmeters are mainly used to measure the volume of flowing liquids, and there are many t...
