Ethanol, an organic compound, molecular formula C2H6O, simple structural formula CH3CH2OH or C2H5OH, commonly known as alcohol. Ethanol can be used to make acetic acid, beverages, flavors, dyes, fuels, etc. Ethanol with a volume fraction of 70% to 75% is also commonly used in medical treatment as a disinfectant, etc. It is widely used in national defense chemical industry, medical and health, food industry, industrial and agricultural production.

Our 80G frequency modulated radar level transmitter measures liquid level and material level, non-contact level measurement, strong anti-interference ability, can overcome the influence of steam, foam and stirring on the measurement, and accurately measure various small-range storage tanks and reactors The liquid level.

Let us take a look at the actual application performance of the radar level transmitter DCRD1000B4.

On-site working conditions and instrument parameters

Production workshop of a chemical company:

Instrument parameters of Radar level transmitter:

Model: DCRD1000B4

Medium: ethanol. Range: 2.50 meters. Process connection: DN125 PN16.

On-site working conditions: The tested device is a refined evaporator, which evaporates the water content in the medium to obtain ethanol with higher purity, multi-layer stirring, and 5-6cm foam.

Remarks: The liquid level instrument used before is a double flange differential pressure liquid level transmitter, and the measurement effect is not satisfactory.

Measurement process

This is an improvement of the measurement scheme. Because the installation port of the reactor is limited and the installation port is inclined and non-vertical, the radar level gauge needs to be installed vertically on the top to achieve the best measurement results. At the initial installation, although it was installed diagonally, the 80G FM radar level gauge has a relatively small launch angle, and the signal is not affected by the stirring blade. After debugging, the level can be measured.

The following is the measurement effect of the radar liquid level installed vertically, the signal is stronger. Since the measurement for several months, the signal is stable and the measurement is accurate.

Measurement results and analysis

After on-site testing, the 80Ghz frequency modulated radar level transmitter DCRD1000B4 was successfully applied to the level measurement of the ethanol solution in the evaporator, which overcomes the influence of steam, foam and stirring on the measurement, and achieves a satisfactory measurement effect for users。

    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...
