 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 level drops below the safe distance, the alarm will disappear immediately;

b. This alarm appears when the initial debugging tank is completely empty, which can be eliminated by interference suppression.

2. When there is interference echo in the container, then it should:

a、Check whether the level gauge is installed correctly and eliminate installation interference;

b、Can be ruled out by fixed target suppression.

3、If the output current is always 4mA and there is no false alarm, then check whether the output is 0.

4、If the meter head is clogged and the tank is full at the same time, then the parameter settings should be compared. If the parameters are determined to be correct, it can be solved by doing an empty tank spectrum.

When measuring, the measurement range starts from the point where the beam touches the tank low, but under special circumstances, if the tank low is concave or tapered, measurement cannot be performed when the level is lower than this point.

 

At present, our radar level transmitter series products include:

1. Guided wave radar level transmitter

2. 26Ghz non-contact radar level transmitter

3. 80Ghz FMCW Radar level transmitter

4. 120Ghz FMCW Radar level meter

Any inquiry of radar level transmitter, welcome to contact me at any time.

    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...
