        The MDR-3200-PRL  millimeter wave radar is a non-contact planar radar water level gauge for surface water level monitoring, based on electromagnetic wave ranging technology for accurate measurement. The sensor transmits electromagnetic waves to the surface of the water and receives its echo, thereby obtaining information such as the distance from the surface to the electromagnetic wave transmitting point, distance change rate (radial velocity), orientation and height.

        The equipment belongs to the innovative application of ranging radar in the field of water level measurement, achieving high water level precision (millimeter level), small volume, large range (30m), reliable accuracy, stable information, easy installation, maintenance-free technology span; Compared with the traditional horn type water level gauge, it has greater function improvement.

        The main structure includes: transmitter, transmitting antenna, receiver, receiving antenna, signal processing, transmission unit, power module, data acquisition equipment, anti-interference and other auxiliary equipment.

MDR-3200-PRL 平板雷达水位计安装说明/Flatbed radar water level gauge Installation instructions:

非接触式雷达产品在复杂密闭环境下电磁干扰有可能导致测量数据不准。

请正确的安装使用本产品，非正确安装方式会导致测量数据不准确。

1、产品安装后必须稳固，不会因外界因素导致晃动。

2、雷达平面与被测量水面必须保持平行。

3、严格按照使用说明选择安装点和安装高度。

（1）安装点选择

1）选择水面开阔无遮挡物、无漂浮物或其他不会影响雷达波的的位置，减少环境干扰。

2）当近水面（小于 2m）时，雷达附近建议少或者无大面积金属物体存在，减少多次反射干扰。

（2）安装高度选取

要根据场景选取合适的安装高度。安装高度选择需满足以下条件。

1) 安装高度不可小于雷达测量盲区，不可大于最大测量量程，一般以最大量程二分之一内为最佳。

2) 水位计波束范围必须全部照射于水面，严禁水位计波束范围部分或者全部照射到非水面区域。

3) 水面波浪大且杂的地方安装高度建议高于 2 米，低于最大量程三分之二。

雷达照射水面区域边界与安装高度成正比，雷达照射水面波束宽度“D”与安装高度“H”之间的关系参照：

D = 2*H*tan（5.5°）= 0.192578H ≈0.2H

The electromagnetic interference of non-contact radar products in complex closed environments may lead to inaccurate measurement data.

Install and use the product correctly. Improper installation may cause inaccurate measurement data.

1、The product must be stable after installation and will not be swayed by external factors.

2、The radar plane must be parallel to the measured water surface.

3、Select the installation point and installation height in strict accordance with the instructions.

（1）Selecting an Installation Point

1) Choose a location where the water surface is open without obstructions, no floating objects or other areas that will not affect radar waves to reduce environmental interference.

2) When near the water surface (less than 2m), it is recommended that there is little or no large area of metal objects near the radar to reduce multiple reflection interference.

（2）Selecting the Installation Height

Select an appropriate installation height based on the scenario. The installation height must meet the following requirements.

1) The installation height shall not be less than the radar measurement blind area, not greater than the maximum measurement range, generally within half of the maximum range

Best.

2) The beam range of the water level meter must be fully illuminated on the water surface, and part or all of the beam range of the water level meter is strictly prohibited from being illuminated to the non-water surface area

Domain.

3) Where the water surface is large and miscellaneous, the installation height is recommended to be higher than 2 meters, less than two-thirds of the maximum range.

The boundary of the surface area of the radar irradiation is proportional to the installation height, and the beam width of the radar irradiation surface is between "D" and the installation height "H"

The relationship reference:

D = 2*H*tan (5.5°) = 0.192578H ≈0.2H
