The manufacturing technology of ULR80X series radar level transmitters all come from our company. After being demonstrated by many radar level experts, the quality is guaranteed in all aspects. This series of radar level transmitters has a variety of forms and a variety of installation methods, which can be applied to Most liquid level measurement can completely replace products such as floats and magnetic level gauges. It has many advantages. For example, during the measurement process, its measurement accuracy is not affected by changes in medium density, temperature, pressure, etc.; installation and commissioning are simple, The later maintenance cost is low. It is widely used in petroleum, chemical, pharmaceutical, metallurgy, electric power, food, oil and grain storage industries.
The radar level gauge is based on the time domain reflection principle (TDR). The electromagnetic pulse of the radar level gauge travels at the speed of light. When it encounters the surface of the measured medium, part of the pulse is reflected to form an echo and returns to the pulse along the same path Transmitting device, the distance between the transmitting device and the surface of the measured medium is proportional to the propagation time of the pulse between them, and the liquid level height is calculated.
