What is Nucleonic gauge?
Nucleonic gauges are measuring and analysis instruments exploiting the interaction between ionising radiation and matter. Industry around the world uses this technology to control and improve product quality by optimising processes and saving energy and materials.
What is Nucleonic device?
Nucleonic Gauges are also known as Ionizing Radiation Gauging Device (IRGDs). These are equipment extensively used in many industries. A nucleonic gauge is used for reliable non-destructive measurement and ideal for adverse industrial environments, including high-temperature and high-pressure conditions.
Which is a disadvantage of Nucleonic method of level measurement?
The use of radioactivity for level, limit level, density or mass flow measurement has many advantages in comparison with other measuring methods, but also two disadvantages: nucleonic instruments are somewhat expensive and their operation requires special permits and safety precautions.
What is a radiation gauge?
A radiation gauge is a sealed source device that contains a sealed radioactive source used for gauging or controlling a parameter, such as thickness, level or density in an industrial process.
What is Nucleonic level profiler?
It’s the only nucleonic instrument designed to measure the vertical distribution of gas, oil, water, foam, emulsion and sand in real time and at high resolution. The ProfilerTM GPS provides a window into the vessel, allowing operators to accurately measure and control the distribution of fluid.
How does a nuclear level detector work?
the basic method of measuring the nuclear level is the sending of radiation through the liquid and the intensity of the transferred radiation is measured using a detector. The detector measures the level of energy that reaches it and sends a signal proportional to the microprocessor.
What is nuclear level?
Nuclear level measurement technology has been applied effectively to measure liquids and solids for more than 30 years. the basic method of measuring the nuclear level is the sending of radiation through the liquid and the intensity of the transferred radiation is measured using a detector.
How do nuclear gauges work?
The nuclear gauge determines moisture by releasing “fast” neutrons that are slowed down, or thermalized, when they interact with the nucleus of hydrogen, a key ingredient of moisture. The Helium 3 tubes in the gauge can only detect “slow” neutrons. It is a very direct relationship, more counts = more moisture.
What is radar level transmitter?
The Radar Level Transmitter is designed specitically for medium/long range measurement of all kinds of power,particle and bulk solids. The compact and high directional system with usage of higher frequency can reazlize the more stable level measurement. Adjustments can be done by entering simple parameters.
What is a nuclear gauge used for?
Nuclear gauges use radioactive sources to identify the thickness, density or make up of a wide variety of material or surfaces. These gauges, which are safe to use when the proper safety measures are followed, help people build safe buildings, roads, and make reliable products.
What level is ultrasonic?
Ultrasonic frequencies are above the levels of sound that humans can hear, typically between 40 and 200 kHz for a level transmitter.
What are some advantages of nuclear gauges?
Portability. One person can easily transport a typical nuclear density gauge.
What are backscatter gauges?
Backscatter method. The backscatter method eliminates the need for an access hole by allowing both the source and detector to remain on the surface. Radiation is directed beneath the surface, where some radiation is reflected, or “scattered”, back to the gauge detector by the surface material.
How do radar gauges work?
Principle of operation Our radar tank gauge employs the frequency modulated continuous wave concept. The distance (i.e. ullage) is derived from the time delay of the reflected signal. A frequency sweeping microwave signal is emitted by the radar tank gauge, and by aid of the antenna directed vertically down the tank.
What is a density meter used for?
Density Meter / Digital Density Meters Density meters are instruments that measure the density of a sample liquid or gas. Digital density meters are used in the pharmaceutical, petroleum, chemical, and food and beverage industries for quality control and in research and development.
What does an NDM measure?
Nuclear Density Meter testing (NDM) is used to test the density and moisture content in soils. The Nuclear Density Meter emits radiation through the soil and detects how much is reflected back to the machine. This helps us calculate degree of saturation, degree of compaction, and air void percentage.
Radiation Based Level Measurement – The Measuring Principal A cesium-137 or cobalt-60 isotope sends out focussed gamma rays. On the opposite side of the tank, a sensor picks up the gamma rays that have been attenuated by the medium. The level can be calculated via the intensity of incoming radiation.
What are the two types of radiation a nuclear gauge used to measure the properties of material?
Gauges can contain a gamma, beta or neutron radiation source. Different sources are used depending on what the nuclear gauge is measuring. Radiation from a nuclear gauge does not make the materials it measures radioactive. Nuclear gauges are either fixed or portable.
What is the unit of density?
Kilogram per cubic meterDensity / SI unit
Which instrument is used for measuring density?
hydrometer
hydrometer, device for measuring some characteristics of a liquid, such as its density (weight per unit volume) or specific gravity (weight per unit volume compared with water).
What is a backscatter density test?
In the Backscatter Method, in-place wet density is obtained by conducting tests on the surface of the material. This method is normally used when determining the density of granular materials. Generally, the Backscatter Method is not used on soils except when the soil is very loose and granular.
What is field density test?
Soil field density test measures relative density of soil which has been compacted using compacting equipment and the result of this test is expressed in %. This relative density is measured by comparing maximum dry density obtained from field test with maximum dry density of laboratory test as a standard reference.
What is ultrasonic level transmitter?
Ultrasonic Level Transmitters are a non-contact level sensing technology that works similarly to radar or sonar. The piezoelectric transducer generates high frequency sound waves in the ultrasonic range.
