The working principle of the radar level meter is similar to that of the radar system, also known as the principle of radio wave reflection. When the radar level meter emits electromagnetic waves, the electromagnetic waves will be reflected by the liquid level surface, part of the electromagnetic waves will be reflected back, and the other part will penetrate the liquid level. These reflected electromagnetic waves are received by the receiver and the liquid level height is calculated by the relative position of the transmitter and receiver. Photo source: Baidu Pictures
Radar level meter parameter Settings are similar, this article is for reference only. 2. Basic Parameter setting 1. Open the table cover and press "Ok" to enter the setting menu. 2. Select Basic Settings and press OK to enter basic Settings. 3. The application type is selected according to the actual measurement medium. In this case, the liquid level of the sink is measured, so "liquid" is selected. 4, container type select "demonstration", demonstration response speed is the fastest. Can also be selected according to the actual container. 5. Set the dielectric constant of the measuring medium.
6. Set the high and low bits. 7, the blind area set 0.3m.
8. The range is set at 5.0m. 9. Set the damping time to 5s.
10. The sensor mode is set to "level".
3, Professional Settings 1, in the menu Settings page, select "professional Settings".
2. Select "False echo Learning". 3, false echo mode, select "select area". 4, "false echo area" data unchanged, directly press "Ok" to enter the next step.
5. Go to the "false echo Learning" page, select "Clear zero" and press "OK". If OK is displayed, clear zero is complete. 6. Select "New" and press "OK" to create a false echo. If OK is displayed, the new echo is created successfully.
7. Press "BK" to return to the display page.
1, instrument simulation: select "Current simulation" in "Professional Settings", you can perform 4-20mA current output simulation. 2, communication function: Modbus communication, Hart communication parameters set in the "bus address" set.
