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

DATE: 2020-07-14
BROWSE TIMES: 11

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.

    Common problems of radar level transmitter Radar level transmitter are mainly installed in various metal and non-metal containers or pipelines to perform non-contact continuous measurement of the level of liquids, slurries and particles. It is also suitable for occasions with dust, inert gas and steam. The radar level transmitter has the characteristics of safety, cleanliness, high precision, long life, stable and reliable, convenient installation and maintenance, and simple reading. Because there are no moving parts, maintenance is minimal, but some minor faults will inevitably occur during use. Here is a breakdown analysis and countermeasures for everyone.1. If an alarm occurs when the liquid level is within the applicable range, then:a. When the liquid leve...

    Radar level meter is a common product type of level meter, which has the advantages of accurate measurement, stable performance, high reliability, easy maintenance, and wide application range. It can be installed in various metal and non-metal containers or tanks to measure the level of liquid, slurry and granular materials. So, under what special conditions will it be installed?1. Selection under the condition of stirringIn a tank with stirring, guided wave radar level gauges are generally not used. The strength of stirring can easily bring the cable of the guided wave radar into the stirring device, or bend the rod of the guided wave radar. So you can only choose non-contact measurement of FM or high-frequency horn-mouth radar level meter to measure.2. Selection under vacuum conditionsUn...

    Radar level meter measures ammonia in a fertilizer plant Ammonia refers to an aqueous solution of ammonia with a strong pungent odor and weak alkaline. Store in a cool, dry, ventilated place, away from fire and heat. Avoid direct sunlight and keep the container tightly closed. It should be stored separately from acids, metal powders, etc. Open-air storage tanks must have cooling measures in summer. Ammonia is often used in agricultural fertilizers, in the chemical industry for the manufacture of various ammonium salts, aminating agents for organic synthesis, and catalysts for the production of thermosetting phenolic resins. In the textile industry, it is used in wool spinning, silk, printing and dyeing industries, for washing wool, woolen cloth, grey cloth, oil stains, dyein...
