Radar Level Gauge Quick Installation Guide
A standard installation
- The radar antenna cannot tilt to the tank wall.
- In order to minimize temperature effect, at the junction of butt joint flange must use the spring washer.
- The rod antenna launching point must reach out to install pipe.
- The vertical placement of the rod antenna beam direction, don’t let the tank wall.
- The recommended position (2), the outer wall of tank wall to install pipe shall meet the following from the tank wall best distance to tank diameter of 1/4 or 1/6, the minimum distance from the installation of tank wall as the measurement range of 1/10.
- For example: liquid level of storage tank 10m, and the tank wall install the minimum distance of 1m.
- Cannot be installed above the feeding port (4).
- Cannot be installed in the central position (3), if installed in the central, yield multiple false echo, clutter echo will lead to real signal loss.
- If you can’t keep the instrument and the tank wall of the tank wall distance, the medium will adhesion caused by false echo, when debugging instrument should be false echo storage.
- The top conical tank level, can be installed at the top of the tank is intermediate, can guarantee the measurement to the conical bottom.

26g Radar Level Meter
The radar level gauge uses a transmission frequency of up to 26G, which has the following advantages over 6G radar:
- The high-frequency radar level meter (mainly 26GHz) has high energy and small beam angle. Generally, the beam angle of a Φ95mm horn antenna is 8º. When the horn antenna diameter of a 6GHz low-frequency pulse radar is Φ246mm, the beam angle is only 15º. The advantages of small antenna size and high precision.
- The wavelength of the 26GHz radar is 11mm, and the wavelength of the 6GHz radar is 50mm. When the radar measures the bulk material level, the radar wave reflection mainly comes from the diffuse reflection of the material surface. The intensity of the diffuse reflection is directly proportional to the size of the material. It is inversely proportional to the wavelength. Most bulk materials The straight length of the material is far less than 50mm. 26GHz radar is the best choice for bulk material level measurement.
- In the application of some small tanks with small diameter and short height. When the medium in the tank or the strong corrosive medium has volatile gas, the effect of ultrasonic measurement is poor. The radar effect is good. The 6GHz radar antenna length (300-400mm) is invisible Increase the blind area (about 600mm). Due to the poor directivity of the 6GHz radar (large opening angle), multipath reflections will occur in a small tank. The 26GHz radar frequency is high and the antenna is short. The directivity is good. It overcomes the shortcomings of the 6GHz radar. Suitable for small tank measurement.
- Due to the harsh site environment, dirt and water vapor will accumulate on the radar antenna over time. The 26GHz radar antenna is small. Adding a radome can greatly improve the impact of dirt and water vapor. The 6GHz radar frequency is low. The antenna size is large. An antenna is added. The cover is very difficult. The overall instrument is large and it is difficult to clean up.
- Due to the good directivity of the 26GHz radar. Many harsh working conditions can be measured by simply isolating the radar outside the container.
- Adopting advanced microprocessor and unique EchoDiscovery echo processing technology. Radar level gauge can be applied to various complicated working conditions.
- Adopting pulse working mode, the transmitting power of the radar level meter is extremely low. It is installed in various metal and non-metal containers. It is not harmful to the human body and the environment.
