RT-type guided wave radar water level gauge is a high-tech instrument that measures and observes the change of water level in the pressure vessel. It is a top-down measurement system based on the principle of time travel. It is widely used for water level monitoring of steam boilers or other pressure vessels in power plants, petrochemical industries and various industrial and mining enterprises. It adopts the display mode of soda red and water green, full red when no water, full green when full of water. The scale indicated at the junction of red and green is the actual water level in the container.

Working principle
Guided wave radar water level gauge is a top-down measurement system based on the principle of time travel, which measures the distance from the reference point to the surface of the material. The high-frequency pulse signal is transmitted to the probe and propagates along the probe. The pulse signal is reflected on the surface of the material, and the reflected signal is received by the instrument and converted into level information. This measurement method is called time domain reflectometry. After the pulse signal is transmitted to the instrument along the probe, the signal analysis is performed by the microprocessor in it, and the real reflection echo of the high-frequency signal on the surface of the material is identified, thereby displaying the real water level.

Technical advantages
The RT-type guided wave radar water level gauge adopts the original imported head, and a heat sink is installed between the head and the connecting flange, so that the water level gauge can operate safely and stably in a high temperature environment. This type of water level gauge adopts a new type of LED light source, which has the advantages of energy saving, long life and clear display. RT-type guided wave radar water level gauge has the function of remote transmission, and can output 4-20mA signal (with Hart protocol) to connect to DCS, and then monitor the water level and control the industrial process.
