The technology surrounding the radar level gauge has vastly improved in the last ten years, mainly due to the innovative leaders continuously improving radar technology. They have made non-contact radar transmitters a level estimation technique that is to easy to use and understand, offering a real usable alternative to differential pressure transmitters and displacers. Let's look at some questions that you might have about radar level gauges.
What are the Main Industries Radar Transmitters are used in?
The radar level gauge is very industrially friendly, as it can be used for level estimation of both solids and liquids in all sort of environments - I mean just look at the examples of where you can use it below.
Where Can I Use a Radar Level Gauge?
As mentioned above, you can use these non feel radar transmitters for level estimation in tanks and vessels for liquids and solids. In fact, you can use them for roughly any liquid and solids in processing or storehouse environment because this technology is so versatile. This versatility means that the radar estimation is not affected by changes in the process like dust, temperature, gas vapors or pressure. As the radar gauges are non feel and versatile, you can rely on their performance.
The most modern and innovative radar estimation units have built in linearization software, which calculates the level versus shape and provides a volume output on the following example types of application:
- Level estimation in processes that use vessels, mixers, blenders, reactors and scrubbers.
- Liquid applications where hygiene is of utmost importance like distillation and purified water. Radar is even convenient for water applications with water sprays.
- High temperature molten applications like metals, coke products and minerals can be monitered effectively with radar transmitters.
- storehouse vessel tank gauging.
- Measuring the interfaces on liquids in difficult applications
How does Radar Transmitter estimation Work?
Millions of short microwave pulses are generated every second by the electronics and transmitted out of the instrument using whether a rod or horn antenna system. The pulses are directed down to the liquid or solid outside by the antenna law and are reflected back to the instrument. It is known that the pulses travel at the speed of light, which means that measuring the time taken in the middle of transmission and receipt of a pulse can give the distance that the pulse has travelled, and hence the distance to the stock surface. This process is a continuous measurement.
Why Should I use Radar Level Measurement?
Because radar transmitters are so versatile, they can fit into your process by being top mounted, side mounted and even put on the outside, as the radar works through glass or plastic. Using a radar level gauge also has the following advantages:
- You can maximise your vessel capacity with very small blocking distances
- You can install or change radar transmitters without the need to empty your tank , so the process will not be interrupted.
- Once again the process does not need to be interrupted when commissioning, which can be accurately done on or off line, without the need to change the level
- The radar level gauge has no inviting parts, which means there will be no drift or recalibration required.
- Radar level gauges cope agitators and obstructions beyond doubt using specialized software
How dependable is Radar?
The good brands have Sil 2 (Iec 61508/615011) conformance on their radar level gauges, which is a extra evaluation required for high integrity applications. To get this conformance the radar gauges have been tested for reliability and carrying out for use on risky processes or products. These types of radar transmitters can be reliably used for level switching (high and low), interface measurement, continuous level estimation and tank gauging.
