An Introduction to Radar Level Gauge
A radar level gauge is a device which is used to measure the level of a substance contained within a tank or a silo. This type of device is essentially a type of radar which transmits surface waves or radio signals, and receives echo signals which reflect off the surface. This type of device is useful because it allows the user to measure the level of a contained substance without the need to get into the container. This type of equipment has become increasingly popular due to its effectiveness in accurately measuring the level of contained substances, as well as its safety characteristics.
Radar level gauges are composed of two basic components; the transmitter and the receiver. The transmitter sends electromagnetic waves from the level gauge to the surface of the contained material, and the receiver picks up the echo signals which return from the surface of the material. By measuring the time which it takes for the signal to travel from the transmitter to the receiver, the level can be determined. Radar level gauges are particularly useful when dealing with difficult to measure substances, such as liquids within an enclosed container.
One of the most commonly used types of radar level gauges is the FMCW (Frequency Modulated Continuous Wave). This type of radar level gauge is used primarily in applications that require high accuracy, such as the monitoring of slurry. The FMCW radar level gauge is unique in that it uses continuously varying frequency, which increases resolution and accuracy. Additionally, this type of radar level gauge is unaffected by vapor, steam and dust, allowing it to be used even in difficult environments.
Another type of radar level gauge, and one which is gaining in popularity, is the 2D Synthetic Aperture Radar (SAR). This type of radar, as it is capable of forming a two dimensional image from a single beam, is ideal for use in applications in which high levels of imaging detail is required. The SAR level gauge is suitable for applications in which high accuracy is required, as it is capable of producing highly detailed images of the substance being monitored. This type of device is particularly desirable due to its resistance to dust and other particles, making it an ideal choice for assessing the level of materials in a hazardous environment.
Overall, radar level gauges are an invaluable device when it comes to measuring the level of contained substances. These devices are capable of accurately and quickly measuring the level of difficult to monitor materials, and are becoming increasingly popular due to their high accuracy, ease of use and resistance to environmental factors. Therefore, if you are in need of a device that can accurately measure the level of a liquid stored within an enclosed container, then a radar level gauge may be the perfect solution.
