Principles of gamma ray densitometry - ScienceDirect
2000年12月1日 · Principles of gamma ray densitometry The use of gamma rays provides an important non-destructive method for determining the density of PM and other powderbased components. Its use within press shops can reduce tool setup times and improve press utilization.
Density measurement with radiometric sensor MINITRAC - VEGA
In radiometric density measurement, an isotope emits focussed gamma rays. The detector on the opposite side of the pipeline receives the radiation. The scintillator of the detector converts the gamma radiation into signals, whose number is detected and evaluated.
DENSITY MEASUREMENT - Berthold Technologies GmbH & Co.KG
The radiometric measurement of density is based on the Gamma transmission principle. Gamma radiation is attenuated as it passes through a pipeline. The extent to which the radiation is attenuated is dependent on the density of the medium in the pipeline.
Development of an intelligent dual-beam gamma densitometer …
2023年9月1日 · This work presents the design, construction, and performance evaluation of a reliable, compact, and economical dual-beam gamma densitometer for real-time monitoring of two-phase flow in industrial applications.
Gamma Densimetry - Helmholtz-Zentrum Dresden-Rossendorf, …
2023年10月1日 · Gamma densitometry has been used in our department for reference purposes to various two-phase measuring techniques. The advantage of gamma densitometry is to measure the void fraction absolutely and contactless. The absorption of gamma rays within a medium only depends on density and atomic number.
gamma ray densitometer | Energy Glossary
A device for measuring the density of fluids in a completed well, using a radioactive source of gamma rays and a detector. In most instruments, a 137Cs (cesium) or 241Am (americium) source is used to induce Compton scattering, as in the openhole density measurement, except that the device is unfocused. The count rate at the detector then ...
Gas Fraction Measurements using Single and Dual Beam Gamma …
Gamma-densitometry is a widely used non-intrusive measurement technique to measure the local gas fraction of gas-liquid two-phase pipe flow. The ability to accu.
A high‐precision gamma densitometer for quantifying skeletal density …
2017年6月7日 · Measuring density in coral skeletons with high precision is challenging and forms the dominant source of experimental uncertainty in related studies. To reduce this uncertainty, we developed a precise and easy-to-handle γ-densitometer.
Gamma densitometry - (Fluid Dynamics) - Fiveable
Gamma densitometry relies on the principle that different materials attenuate gamma rays to varying degrees, allowing for density determination. This technique can be applied in both laboratory settings and in-field measurements, making it versatile for fluid dynamics studies.
Design of a Gamma Densitometer for Hydrocarbon Fuel at High …
The densities of endothermic hydrocarbon fuel at supercritical pressure condition are measured online using a radial measurement method. The densitometer is based on the attenuation theory of gamma...
