Working Principle

GML801-C transmits and receives very short microwave pulses with very low energy through the antenna system. Radar waves travel at the speed of light. the running time can be converted into a level signal by electronic components. --A special time extension method can ensure stable and accurate measurement in a very short time.
Even if the working conditions are more complicated and there are false echoes, the latest micro-processing technology, and debugging software can accurately analyze the level echoes.

Product Features

1. the intelligent radar level meter uses advanced microwave processing technology and unique Echo Discovery echo processing technology. the product can be applied to various complicated working conditions.
2. "False Echo Learning" function enables the meter to accurately identify true echoes under multiple false echo conditions, thereby obtaining accurate measurement results.
3. A variety of process connection methods and types of detection components can be customized according to customer needs.
4. Using pulse working mode, the product's transmitting power is extremely low, and it can be installed in various metal and non-metal containers without harming the human body and the environment.

Installation Requirements

the radar level gauge is installed at 1/4 or 1/6 of the diameter. Note: the minimum distance from the tank wall should be ≥300mm.
Can not be installed above the feed inlet. It cannot be installed in the center position, as shown in Figure 1.
in the signal beam, the following obstacles 1 2 should be avoided, as shown in Figure 2. (If it is unavoidable, use a guided-wave tube for measurement.) the beam transmitter of the rod radar must extend and install a short tube, and the length of the tube should not exceed 15cm, as shown in Figure 3.
the horn antenna must extend out of the installation short tube, the horn antenna must be adjusted to vertical, do not let the radar beam point at the tank wall, as shown in Figure 4.
