1. Product Overview
Radar level sensor antenna emits and narrow microwave pulse. This pulse propagates in space at the speed of light. When it encounters the surface of the measured medium, part of its energy is reflected back and received by the same antenna. The time interval between the transmitted pulse and the received pulse is proportional to the distance from the antenna to the surface of the measured medium. The 80GHz intelligent series radar level gauge is suitable for non-contact continuous measurement of the level of liquid, slurry, granular material and block material. Applicable In the occasions where temperature and pressure change greatly, inert gas and volatilization exist.
The hardware system uses advanced microprocessors and embedded system processing software. The signal algorithm processing integrates advanced Echo-capture signal processing technology. This makes the product applicable to various complex industrial plant conditions.
The “empty tank pretreatment” technology enables the instrument to correctly identify effective echoes and obtain correct measurement results even in the presence of multiple false echo interference.
Not affected by various complicated working conditions. Such as strong surface fluctuations, foam, moisture and dust interference.

5. Installation
Two points for installation:
(1) Align the target material level to ensure that it is perpendicular to the material level plane;
(2) Avoid false echoes. See the following points for typical working conditions.
● Ensure that there are no interfering objects, such as ladders and steps, within the beam range.
Figure 5 – 1 Schematic Diagram of Instrument Installation Position
● The instrument installation shall ensure that the antenna beam avoids the feed inlet, as shown in Figure 5-2.
Figure 5 – 2 Antenna beam avoiding feed inlet
● The instrument shall be installed at least 20cm away from the vessel wall, otherwise it is likely to produce wrong readings, as shown in Figure 5-3.
Remarks: The liquid measurement installation spool should be perpendicular to the ground.
Figure 5 – 3 Installation at least 20cm away from the vessel wall
● The solid cone container shall ensure that the beam is directed at the tank bottom as much as possible, otherwise the measurement results at the tank bottom may be inaccurate, as shown in Figure 5-4.
Figure 5 – 4 The conical tank shall ensure that the beam is directed at the tank bottom as far as possible.

In four wire system application, 4-20mA analog output is two separate terminals except 24V power supply terminal. At the same time, the four wire system also provides 485 output terminals, which is convenient for connection and debugging with PC or the site requiring 485 interface.
6.2 Wiring diagram of single chamber enclosure 24VDC power supply two-wire product

In the two-wire system application, in addition to the traditional power supply terminal (4-20mA output), the instrument also has a serial communication terminal, which is convenient to connect with the current mainstream IOT equipment or transparent transmission equipment for remote control and debugging.
