We provide a range of advanced nucleonic instrumentation to the process industry, including instruments for level measurement, density measurement and . Nuclear based level measurement sensors can be used for point as well as continuous level measurement applications. The concept of nuclear level sensors is. 17 Apr The radiation intensity of nucleonic devices for measurement of level, limit level, density or mass flow is so low today that a conventional Geiger.

Operator confidence to increase production and maximise throughput by running at the desired level, avoiding the negative impact of ‘losing’ real liquid or slurry levels.
Achieving predictive maintenance using an oil condition monitoring system Monitoring the condition of lubricating oils is an important part of predictive maintenance. This radiation protection container allows the radiation to exit only in the direction of the receiver detector and shields off the radiation in all other directions.
These radiations passes through the vessel walls and material gets accumulated towards the detector. The first difference between a nucleonic gauge and other technologies is, of course, the radiation protection container, which encloses the capsule with the barely rice-grain-sized bucleonic of radioactive isotope.
Retrieved from ” http: At first glance, a nucleonic gauge is not really that much different from other gauges which operate according to the same principle, using radar, ultrasound or microwaves: Advances in temperature calibration procedures Recent developments eliminate the need for unnecessary calibrations and speed nuclelnic the time it On arrival on-shore, the gas is removed from the oil fraction and is recompressed for onward distribution.
In medicine, it has revolutionised many areas of diagnosis and therapy, particularly cancer therapy. Slow measured value changes, however, lead to a longer time constant in the detector and therefore to high measuring precision.
Advances in temperature calibration procedures. However, since this technology uses radioactive radiation, safety is the top priority. Second, the long half-life of a radioactive Cs source makes possible a long service life without source exchanges.
First, Cs can be shielded much better than Co in the radiation protection container. The sample itself is a small piece of radioactive substance encased in a double-wall stainless steel cladding.
The radiation intensity of nucleonic devices for measurement of level, limit level, density or mass flow is so low today that a conventional Geiger counter does not respond to it at all.
The use of nucleonic gauges — instruments, which utilize the unique properties of radioactive materials to provide, means of analysis, measurement and control — is widespread throughout the industry.
The transmitter sends signals in transmityer direction of the medium that is to be measured, and these signals are picked up by the receiver installed on the opposite side of the medium. We provide a range of advanced nucleonic instrumentation to the process industry, including instruments for level measurement, density measurement and phase measurement. The radiation is focused and directed in a narrow beam to the detector.
The larger the amount or density of the medium, the more the signals are attenuated on their way to the receiving device. The external mounting of the instrument means that process break-ins are kept to a minimum. During the extraction of Hydrocarbon from the North Sea, the gas fraction has to be recovered and part of the re-injection into the oil for transportation by pipeline from the offshore well-head to the onshore terminal.
In the case of Co radiators, a source exchange is necessary after about seven years due to the shorter half-life. In case, the vessel contains no contents, transitter transmitted gamma rays arrive at the transmiitter. This component has two functions – on the one hand, it protects the surroundings from the radiation and on tranmitter other, it nuclsonic the capsule containing the radioactive material from mechanical or chemical damage.
The reason was fairly easy to identify.
As of late, however, nucleonic devices developed according to SIL specifications for continuous level measurement and level detection, as well as interface and density measurement, are also available on the market. The instrument is unaffected by temperature and process conditions. Transnitter radiation can also penetrate metal very effectively, but is strongly attenuated and scattered by any substance containing hydrogen e.
Improving safety In order to raise the SIL level for nucleonic gauges, the developers began with the points already mentioned: The specific type and quantity of radioactive source material depends on the nature and intensity of radiation required for the application. The major source utilized in nucleonic level controls includes gamma radiations. The Safety Integrity Level SIL serves as an evaluation of electronic systems with regard to the reliability of their safety leve.
X96 Series Non-Contact Mould Level Measurement System
More sensitive detectors, sources with lower radiation intensity and improved radiation protection containers have improved the safety of nucleonic gauges. The radiation outlet is adapted to the respective application and can be closed off completely when required: Following are the major advantages associated with the use of nucleonic method of level njcleonic. Many uses, greater safety Nucleonic gauges are being used in more and more areas of process engineering.
Other types of nuclear radiation are scattered by process material in vessels, which means the level of process material may be sensed by sending radiation into the nucleonif through one wall and measuring back scattered radiation returning through the same wall. The entire system was installed and calibrated with the plant on-line and being completely non-invasive, offered a high degree of reliability.
Our worldwide onsite training sessions cover its range of instrumentation so you can have all the information you tfansmitter to run your business safely and effectively. The nuclei of these isotopes are unstable, decaying over time to become different elements. Gamma rays are emitted from the source and are focused to travel through the tank wall, the medium in the tank and the far tank wall through to the transmither.
However, they have comparatively higher energy and shorter wavelength owing to which these radiations are competent enough to break through the walls of process vessel and material.
