Instrument Knowledge|How to install DCRD1000A series radar level gauge correctly?

DATE: 2020-07-14
BROWSE TIMES: 6

The DCRD1000A series radar liquid level gauge is a 26G high-frequency, non-contact radar level measuring instrument. It has the advantages of high performance, high precision and long service life. It can adapt to the harsh production environments of high temperature, high pressure, steam, dust, etc. The maximum measuring distance can reach 70 meters.

 

So, how to properly install the radar level gauge to ensure that the meter can work normally? Please see the following notes:

 

1. Installation Space

1) Installed at 1/4 of the diameter, and the minimum distance from the tank wall is greater than 250mm

2) Note: ①. Reference plane ②. Center of container or axis of symmetry

2. Conical tank installation

  The top surface of the conical tank can be installed in the middle of the top of the tank to ensure that the bottom of the cone can be measured

3. Solid pile

For solid materials, there are piles or nests, and the antenna should be aimed at the surface. If the material surface is uneven and the cone angle is too large, you must use a universal flange to adjust the antenna angle so that the antenna is aligned with the material surface as much as possible.

4. Material inlet port

1) The radar cannot be installed above the feed inlet;

 

2) When installing outdoors, sun-shading and rain-proof measures should be taken.

 

3) As shown in the figure: ①. Correct ②. Error

5. Arched and round tanks

When the radar is installed in the middle of the arched and round tank roof, it will not only produce indirect echoes but also receive the effect of multiple echoes; the multiple echoes may be greater than the threshold of the real echo, because multiples can be concentrated through the top Echo; therefore, the radar cannot be installed in the middle of the arched, round tank roof

6. Obstacles in the tank

There are obstacles in the area radiated by the transmitted microwave beam, such as human ladders, limit switches, heating equipment, brackets, etc., which can cause interference and lead to measurement errors. If it is affected, you need to add a guided wave tube for measurement.

7. Takeover height requirements

It must be ensured that the antenna is at least 10mm deep into the tank.

    Instrument knowledge|Radar level meter, how to reduce the interference in the tank on the measurement When we install the radar level meter, we will encounter many on-site storage tanks with supports, such as beams and brackets,etc . . . These supports will interfere with the signal of the radar level meter. If the above interference objects appear in the radar emission area, when the normal liquid level is below the interference objects, it will inevitably affect the normal measurement of the radar level meter, and false echo signals will appear. When encountering such situations, there are the following solutions: Method 1: Cleaning up on-site interferenceIf the interference is too large, completely occludes or most of the transmission signal of the radar level meter,...

    When selecting the type of radar level gauge, consider the influence of stirring and vacuuming, and pay attention to the power supply and output signal.1. Selection under stirringIn a tank with stirring, guided wave radar is generally not used. The force of stirring can easily bring the cable of the guided wave radar into the propeller, or bend the rod of the guided wave radar. Therefore, only high-frequency or low-frequency horn radar for non-contact measurement can be selected.If the lowest liquid level on site is above the stirring propeller, it generally has no effect on the measurement. If the minimum liquid level will be lower than the stirring propeller, it is necessary to filter out the signal reflected by the propeller by learning the function of false echo, so as to ensure that t...

    Intelligent radar water level meter helps carry out flood prevention workRecently, as tropical disturbances in the southern coastal areas of my country have developed into tropical depressions, heavy rainfall has appeared in many areas of southern my country, and the flood control warning has been sounded. Since my country entered the flood season, a new round of flood control and early warning work has once again been put on the agenda. In flood warning work, the status of monitoring instruments can hardly be shaken. In order to do a good job in flood control and early warning, and prevent problems as much as possible, the intelligent radar water level meter DCRD1000A2 researched and developed by Xi'an Dechuang Electrictrical Technology Co., Ltd. not only greatly improves the measurem...

    Why choose the radar level sensor in industrial process level instruments? The radar level sensor can measure the level that many other level instruments cannot measure, radar level sensor uses the microwave pulse measurement method and can work normally within the specified frequency range. It can be used in environments where inert gases and volatilization exist under the interference of temperature or pressure changes. The radar level sensor is a non-contact continuous measurement type process level instruments, which can be used to measure the level of liquids or solids, particle sizes and particulate materials. It corresponds to 4-20mA output, which is set by inputting the empty tank height E (=zero point), the full tank height F (=full scale) a...
