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.

    The 120GHz FMCW radar level transmitter was successfully applied to the measurement of coal ash conditions in a chemical plant.Fly ash is a kind of product with relatively low dielectric constant. The dust in the measurement environment is very heavy , and some temperatures are still relatively high. It is a relatively difficult condition to measure, but our company's 120G FMCW radar level transmitter was successfully applied to the measurement of coal ash conditions in the chemical plant, and the measurement effect is good with stable signal.                                  The Main Feature of 120GHz FMCW Radar level Transmitter:1. Not be affected by atmospheric precipitation;2. The ambient tem...
