NYRD702 1.8GHz Guided Wave Radar Level Meter

The guided wave radar level meter is a level meter based on the principle of time domain reflection (TDR). The electromagnetic pulse of the radar level gauge propagates along the steel cable or probe at the speed of light. Part of the pulse of the level meter is reflected to form an echo and return to the pulse transmitter along the same path. The distance between the transmitter and the surface of the measured medium is proportional to the propagation time of the pulse during that period, and the liquid level height is calculated.

Radar Level Meter Operating Principle

The high-frequency microwave pulse emitted by the guided wave radar propagates along the detection component (steel cable or steel rod), and when it encounters the measured medium, due to the sudden change of the dielectric constant, it causes reflection, and a part of the pulse energy is reflected back. The time interval between the transmitted pulse and the reflected pulse is proportional to the distance of the measured medium.

Radar Level Meter Design Features

◎ Guided wave radar level meter adopts advanced microwave processing technology and unique Echo Discovery echo processing technology, contact measurement, high measurement accuracy and more accurate measurement. At the same time, the guided wave radar is resistant to adhesion and is not affected by the external environment such as medium temperature and adhesion.
◎ A variety of process connection methods and types of detection components make 70X series guided wave radar level gauges suitable for various complex working conditions and applications. Such as: high temperature, high pressure and small dielectric constant medium.
◎ Using pulse working mode, the product has extremely low emission power, and can be installed in various metal and non-metal
containers without harm to human body and the environment.

Radar Level Meter Installation requirements

Standard installation method

◎ It is recommended to install at 1/4 or 1/6 of the container diameter.
Note: The minimum distance from the tank wall is L0≥300mm, H0≥50mm.
◎ Keep away from the inlet and outlet.
◎ Keep clear of obstacles such as limit switches, heating coils, agitators, etc. Note: The distance between the probe and the obstacle is ≥200mm.
◎ When the container is a metal can, the radar should not touch the wall and bottom of the can in the whole range.
◎ If the bottom of the container is tapered, the radar can be installed in the center of the top of the tank.
◎ The height of the installation short pipe should be L1≤10cm.
