Conditions inside the separator were extremely foamy and, if adequate level control was not maintained oil droplets or even slugs of oil, were carried forward with the gas to the compressor. Nuclear or nucleonic level transitter devices can be employed in both point and continuous level detection applications. As a result of its design, the radiation protection container offers maximum protection with minimal weight.

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: We provide a range of advanced nucleonic instrumentation to the process industry, including instruments for level measurement, density measurement and phase measurement.

The sample itself is a small piece of radioactive substance encased in a double-wall stainless steel cladding. Retrieved from ” http: Whoever wanted both had to go for a stronger radioactive radiation source.

This means nuclear-based level sensors using Cesium will be more stable over time i.

Nucleonic measurement

Automation solution a reason for popping corks. Discover how our proven next generation bulk level and interface solutions provide our customers with unparalleled performance and reliability and why this innovative instrument range was recognised by the Institute of Physics. Advances in temperature calibration procedures.

Industrial vs commercial ethernet. In general, the gamma source emitting radiations is located external to the process vessel. The detector is installed on the other side of the vessel. The trade-off is that Cobalt emits more powerful gamma rays than Cesium, which makes it better suited to applications where the radiation must penetrate thick process vessels or travel long distances across wide process vessels.

They came to the realisation that each measurement application requires an individual decision about which factors are important for the measurement.

Impinging gamma radiation generates flashes of light in the crystal or plastic scintillator. Multiple gamma sensors, mounted outside the tank, help see through buildup on tank walls for a true level reading.

Slow measured value changes, however, lead to a longer time constant in the detector and therefore to high measuring precision. Nucleoinc rays are emitted from the source and are focused to travel through traansmitter tank wall, the medium in the tank and the far tank wall through to the detector. 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 nuclei of these isotopes are unstable, decaying over time to become different elements. Unique processing algorithms provide unparalleled insight into vessel operating conditions, monitoring what occurs in the vapour space allowing the extent of deposition to be identified. The second way is SIL-certified device development. But it is nonetheless radioactivity, and so nucleonic gauges must be one thing above all: Only a narrow slit remains open through which the radiation can exit, focused in the direction of the detector.

Major characteristics of gamma radiations which make them useful over other technologies for level measurement applications are listed below:. Depending on how the device was calibrated, the impulse rate is converted by the processing electronics into a level, switching, density or concentration signal.

Apart from Gamma ray radiation, the other common source of nuclear radiation is neutrons. First, Cs can be nuclronic much better than Co in the radiation protection container.

Failure of the gas compressor was a recurrent problem. The importance of on-line measurement and control will of course be readily appreciated in the context of ensuring that the product conforms to requirements. In medicine, it has revolutionised many areas of diagnosis and therapy, particularly cancer therapy.

By placing a radioactive source on one side of the vessel and measuring the radiation making it through to the other side of the vessel, an approximate indication of level within that vessel may be obtained. Improving safety In order to raise the SIL level for nucleonic gauges, the developers began with the points already mentioned: The major source utilized in nucleonic level controls includes gamma radiations. Home Business Units Measurement Instruments Nucleonic Instrumentation We provide a range of advanced nucleonic instrumentation to the process industry, including instruments for level measurement, density measurement and phase measurement.

Newer Post Older Post Home. In the case of Co radiators, a source exchange is necessary after about seven years due to the shorter half-life. The field strength of these gamma radiations is determined by a sensor mounted on the other end of the vessel, which ultimately detects the level of process material in the vessel.

On the receiving side, the detector contains a scintillator, a photomultiplier and evaluation electronics. The first difference between a nucleonic gauge and other technologies is, of course, the radiation protection container, which encloses the capsule trabsmitter the barely rice-grain-sized particle of radioactive isotope. With enhanced self-diagnostics transmifter unrivalled stability it is renowned for high accuracy, high levels of reliability and, as a result, extremely low maintenance costs.

It is able to detect and monitor solid deposition. Achieving predictive maintenance using an oil condition monitoring system Monitoring the condition of lubricating oils is an important part levle predictive maintenance.

Inthe French physicist Antoine Henri Becquerel discovered the radioactive radiation of uranium, and thus radioactivity itself. On arrival on-shore, the gas is removed from the oil fraction and is recompressed for onward distribution. 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.

However, since this technology uses radioactive radiation, safety is the top priority. Robust Our robust and fault tolerant hardware is proven in use for high operating temperatures. The expression “Providing Insight Onsite” is used to describe the clarity and understanding that these products are bringing to our customers all over the world providing them with the means, and the confidence to increase earnings, manage risks and reduce costs. Compared with some other applications of radioactivity, nucleonic measurement gets by with radiation sources of relatively low intensity.

Indeed, to this day, some areas of application do not allow any alternative to nucleonic measurement. From the strength of the incoming waves, impulses or beams, the software can calculate how full nucleknic container is, how great the density of a medium is and other parameters.
