FEATURES
The radar level gauge adopts a transmission frequency of up to 26GHz, thus possessing:
- Small beam angle, concentrated energy, stronger anti-interference ability, greatly improving measurement accuracy and reliability;
The antenna size is small, making it easy to install and install antenna protective devices such as dust covers;
The measurement blind spot is smaller, and it can also achieve good results for measuring small cans;
- Shorter wavelength, more suitable for level measurement of small particulate matter.

By adopting advanced microprocessors and unique EchoDiscovery echo processing technology, the radar level gauge can be applied to various complex working conditions.

Adopting a pulse working mode, the radar level gauge has extremely low transmission power and can be installed in various metal and non-metal containers without causing harm to the human body and the environment.

Product installation
Basic requirement: When the antenna emits microwave pulses, there must be a certain emission angle. There shall be no obstacles in the area radiated by the emitted microwave beam from the lower edge of the antenna to the surface of the measured medium. Therefore, during installation, it is advisable to avoid facilities inside the tank as much as possible, such as ladders, limit switches, heating equipment, brackets, etc. If necessary, 'false echo learning' must be performed. Additionally, it should be noted that the microwave beam must not intersect with the feed stream. When installing instruments, it is also important to note that the highest material level should not enter the measurement blind zone; The instrument must maintain a certain distance from the tank wall; The installation of the instrument should be as perpendicular as possible to the transmission direction of the antenna and the surface of the measured medium. Instruments installed in explosion-proof areas must comply with the installation regulations of national explosion-proof hazardous areas. The casing of explosion-proof instruments is made of die cast aluminum. Explosion proof instruments can be installed in places with explosion-proof requirements, and the instruments must be grounded.

Illustration Explanation
The reference surface for measurement is the sealing surface of the thread or flange.

Note: When using radar level timing, it is important to ensure that the highest level does not enter the measurement blind zone (area shown in Figure 1).

4 Electrical Connections
Supply Voltage
(4-20) mA/HART (two-wire system):
The power supply and output current signal share a two core cable. Please refer to the technical data for the specific range of power supply voltage. For intrinsic safety type, a safety barrier must be added between the power supply and the instrument.
(4-20) mA/HART (four wire system):

The power supply and current signal each use a two core cable. Please refer to the technical data for the specific range of power supply voltage. The standard instrument current output can be output in a grounded form. Explosion proof instruments must have floating current output. The instrument and grounding terminal should ensure good grounding. Usually, the grounding can be connected to the grounding point of the tank. If it is a plastic tank, it should be connected to the adjacent ground.

Installation of connecting cables
General introduction: The power supply cable uses ordinary two core cables with an outer diameter of (5-9) mm to ensure the sealing of the cable entrance. If there is electromagnetic interference, it is recommended to use shielded cables.
(4-20) mA/HART (two-wire system): The power cable can use a regular two core cable.
(4-20) mA/HART (four wire system): The power cable should use a cable with a dedicated ground wire.

Shielding and wiring of cables
Both ends of the shielded cable should be grounded. Inside the sensor, the shield must be directly connected to the internal grounding terminal, and the external grounding terminal on the housing must be grounded. If there is a grounding current, the shielding end of the shielded cable on the side away from the instrument must be grounded through a ceramic capacitor (such as lnF/1500V) to isolate and bypass high-frequency interference signals.
