Selection of Beidou satellite moisture sensor:

The MS1204 moisture sensor uses the principle of microwave energy attenuation caused by absorption when passing through a substance.

Due to the ratio of the absorption coefficient of moisture to that of oil75:1, when a high-frequency electric field is applied to oil products, the difference in absorption will affect the phase and amplitude of the high-frequency electric field, and the degree of influence is related to the moisture content.

The microwave attenuation moisture measurement instrument (humidity meter) represents a new development in product moisture measurement technology. By using microwave measurement technology, it can be used to measure moisture in productsThe moisture content can be determined within 1 second, and the measurement results are highly accurate and not affected by the particles, color, or any minerals contained in the product.

The MS1204W model can effectively eliminate the influence of oil quality and mineralization in the determination of crude oil water content in oil fields.

The HBD5MS1204 oil moisture rapid tester is a ppm level oil moisture tester developed by our institute, which can accurately determine the water content in various single component or multi-component mixtures.

Comparison of various methods for measuring water content in crude oil:

distillation
Principle: Utilizing the principle of different boiling points and distillation times of crude oil, water, and solvents.

Disadvantages: Long distillation time, greatly affected by the accuracy of quality and volume measuring instruments, and the effect of circulating cooling.

Centrifugation

Principle: The principle of layering in a centrifuge by utilizing the density difference between crude oil and water

Disadvantages: Long distillation time, greatly affected by the accuracy of quality and volume measuring instruments, and the effect of circulating cooling.?

capacitance method

Principle: Utilize the difference in dielectric constant between crude oil and water.

Disadvantage: It is greatly affected by changes in the composition of the measured crude oil and electrolytes in water.

High frequency method

Principle: The principle of using different substances under the action of an electric field to absorb energy by electric dipoles during the transformation process, causing phase changes in electric field voltage and current.

Disadvantage: It is greatly affected by the conductivity of each component and electrolyte.

Coulomb method

Principle: The principle of utilizing the difference in the amount of electricity required for the electrolysis reaction between water and other substances.

Disadvantages: Long testing cycle, affected by dissolved oxygen content and component complexity.

Crude oil water content state:

Adding water and emulsifiers to the oil for emulsification cannot be achieved by distillation, but this instrument can detect it.

Adding salt or soil to the oil, this instrument also has the characteristic of positive response to water. If the true water content is not high,

It may be due to soil or other inorganic salt impurities.

Pure oil without water can be detected for quality, such as calorific value, using this instrument.

The purpose of accurately measuring oil samples in a mixed state of oil and water is only after thorough stirring.

At present, the analysis of crude oil water content in domestic oil production plants mainly adopts distillation and centrifugal separation methods, which are complex and time-consuming. In order to obtain a large number of oil samples in a timely manner, a large number of personnel are required.
