This is a radiation measurement system. Radiation oil and water for each measurement system.

The photon energy of each group is selected so that the sequence of mass absorption coefficients in the gas is 1ζ-order independent of each other.

As the radiation detector (2), a gas-filled proportional counter tube can be used, and measuring instruments such as preamplifiers, Wang amplifiers, and Watari discriminators are routinely used in the field of radiation measurement and are not readily available. There are no difficulties. (1) The arithmetic processing unit mff1 can be easily constructed using a microcomputer. Alternatively, it is also easy to configure this arithmetic processing device with an analog circuit.

Now, the attenuation of radiation in a substance is generally I.

Jn −jPd ■ Described by 1. Ru. Here ■0 is the intensity of incident radiation, ■ is the intensity of transmitted radiation, μ is the radiation absorption coefficient of the material, p
is the density of the material and d is the transmission thickness in the material. Therefore, the radial ia distance of the crude oil in the pipe is D (cm), and the total thickness of the petroleum component is d. , the total thickness of the water component is dW, and the total thickness of the gas component is d. Matatame. , al, μ0 are respectively 11 oil, water,

This can be determined online without using .This is not affected by changes in the temperature and pressure of crude oil, the density of gas, the density of oil, and the density of water.

For reference, specific numerical examples are shown. Am-241 is chosen as one of the radiation sources. This n is 59.5keV and 26.
3keV (7) Gamma ray, 18.9keV,
It emits X-rays of 17.8keV and 20.8keV. Therefore, all of the highest energies below 26.3 keV are collectively regarded as 20 keV X-rays.

Furthermore, it is recommended to measure 59.5 keV gamma rays using a pulse counting type radiation detector using a proportional counter, and since the energy resolution is about 10%, these two OJ
The energy was easily separated and transmitted by one detector.
It should be possible to simultaneously measure the gamma ray and X-ray intensity of volatiles (ζ).
Select d-158. This emits gamma rays of about 100 keys. The gamma rays may be measured by using a proportional counter as described above, or by using a scintillation detector.

Further, in the above example, a Arashi radiation source that emits the first type of radiation and the second type of radiation is used.

The radiation measurement system, from the radiation detector to the main amplifier, was used for two types of gamma rays and X-rays (although we were hesitant to share them).

These are the first radiation source for the first radiation.

20) for second radiation using a first radiation detector, a first preamplifier and a first main amplifier; 20) a radiation source, a second radiation detector and a second preamplifier;

A second main amplifier may be used to provide separate radiation measurement systems for the first radiation and the second radiation.

Alternatively, for AI type radiation, a pulse counting type detection tube may be used and the radiation measurement system from the radiation detector to the triple width detector may be shared.

Alternative 1: An X-ray tube could be used instead of a radiation source.

Furthermore, in the above example, the radiation intensity can be measured using the pulse counting method (although the radiation intensity can also be measured as a direct current using a direct current type detector).

Further, in the above embodiment, a signal proportional to the logarithm of the transmitted radiation intensity is created by the arithmetic processing unit (8), and a logarithmic count rate meter is provided after the wave (discriminator +57 (61) (7), and this portion can be regarded as a radiation measurement system, and this measurement system can be configured to output a signal proportional to the logarithm of the transmitted radiation intensity.

In addition, when the change in the oil quality becomes faster over time, when it is necessary to automatically correct the change in the oil quality, this correction is performed based on the photon energy of the radiation being the first. Second
This becomes possible by providing a fourth radiation measurement system having a different photon energy from the radiation of the eighth radiation measurement system.

Let's consider the case where the fluctuations in the sulfur content in the current oil (ζ) can be automatically corrected.

Furthermore, if beryllium is used as the tube wall material Iζ in the radiation transmitting portion, the attenuation of the radiation in this portion can be reduced, making it easier to measure the transmitted radiation.
