The guided wave radar liquid level meter is based on time domain reflection principle (TDR), the electromagnetic pulse of the radar liquid level meter is transmitted along a steel cable or a probe at the speed of light, when the radar liquid level meter meets the surface of a measured medium, partial pulse of the radar liquid level meter is reflected to form echo and returns to a pulse transmitting device along the same path, the distance between the transmitting device and the surface of the measured medium is in direct proportion to the transmission time of the pulse between the transmitting device and the surface of the measured medium, and the liquid level height is obtained through calculation. The technical advantages of the guided wave radar level gauge are as follows: the radar liquid level gauge measures the continuous level of liquid, particles and slurry. The measurement of the radar level gauge is not affected by medium changes, temperature changes, inert gases and steam, dust, foam, etc. The precision of the radar liquid level meter is 5mm, the measuring range is 60 meters, the radar liquid level meter can resist high temperature of 250 ℃ and high pressure of 40 kilograms, and the radar liquid level meter is suitable for explosion danger areas. The guided wave radar level gauge is applied to water liquid storage tanks, acid and alkali storage tanks, slurry storage tanks, solid particles and small oil storage tanks. Various types of conductive, non-conductive, corrosive media. Therefore, the high-pressure and low-pressure heaters of the thermal power plant mostly adopt the guided wave radar rod as a liquid level monitoring device.

When the guide rod is installed back, the operations are performed in reverse order.

The following disadvantages mainly exist by adopting a manual mode:

(1) in the process of replacing the guided wave rod, because high-temperature and high-pressure gas exists in the high-pressure and low-pressure heater for manual replacement, the personal safety of workers has potential risks.

(2) The working temperature of the high-low pressure heater is 200-300 ℃, and the working temperature of the high-low pressure heater needs to be naturally cooled to the ambient temperature when the temperature of the guided wave rod in the measuring cylinder is reached, so that the long time is consumed, and the equipment maintenance efficiency is influenced.

(3) The length of the guide wave rod is 1.5m, the length of the measuring cylinder is 1.6m, a scaffold needs to be erected after manual dismantling, the weight of the guide wave rod is heavy, a plurality of persons need to cooperate to draw out the guide wave rod from the measuring cylinder, and manpower and physics are consumed.
