How to choose the model correctly for the guided wave radar level transmitter

Guided wave radar level transmitter selection considerations


1.Selecting the guided wave radar level gauge must confirm the viscosity of the measuring medium. If the measuring medium is very viscous, it is not suitable for the contact type measuring method of the guided wave cable rod. The hanging material will affect the transmission of the signal, and the reception will generate a false signal.

   

2. If the measured medium is corrosive, it is necessary to use a guided wave cable sleeve of PTFE or a rod set of PTFE.


3. the definition of the range, the range generally we even install the flange face down to the vertical distance from the bottom of the tank, this parameter must be accurate, the lowest end of the cable probe from the bottom of the tank at least 30mm of the sub space, to ensure that the probe does not touch the bottom of the metal tank to generate interference signals. The cable can be kept longer, so that it can be cut if long. but if it is short, it needs to be re-customized. We must confirm the length of the cable when determining the parameters, so as to avoid the normal measurement at the site.


4. Select the guided wave radar level gauge to confirm whether there is a position of the stirring fan blade in the tank.  If the fan blade is close to the pipe wall, then the GWR level transmitter is not suitable for use , or by adding a bypass pipe to measure it,Or the pole should be at least 300mm from the pipe wall.

   

5. If the measured dielectric constant of the liquid medium is very low, you can refer to the radar level gauge with the guided double cable, the effect will be better.


6. There are two ways to fix the end of the probe if it needs to be fixed: insulated and non-insulated.

(1) Insulation fixing refers to the way of insulation fixing when the measured dielectric constant is low and fixed at the bottom of the metal can.

(2) Non-insulating fixing refers to the non-absolute fixing method used when the dielectric constant of the measured medium is high and the tank is made of metal, the dielectric constant is very low, or the material with the dielectric constant of the measured medium is very close.

    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...
