How to select radar level meter

In the selection process of radar level meter, Fuzhou Shengbo Electronics Co., Ltd, as a professional radar level technology provider and original equipment manufacturer (OEM), its products and technical strength provide a wealth of options and support for selection. The following is a detailed analysis based on the selection steps and considerations provided by you, combined with the product characteristics of Fuzhou Shengbo Electronics Co:

First, clear measurement requirements

Measuring range: Determine the height of liquid level or solid material to be measured, and consider whether a certain range margin needs to be reserved.
Measurement accuracy: Understand the required measurement accuracy, and select the accuracy level of the radar level meter to match the demand. The accuracy of the radar level meter is usually between one and five percent, depending on the model and accuracy level of the selected equipment.

Second, consider the characteristics of the medium

Media type:
Determine the type of medium to be measured (liquid, solid), as well as the specific name and characteristics. For example, for liquids susceptible to interference, you can choose a radar level meter with low scintillation technology; for media with high viscosity or concentration, you should choose a radar level meter with a small angle measurement function.
If it is liquid, you also need to consider whether there is vapor, mist, foam, waves, agitation, floating objects, etc. on the liquid surface.
If it is a solid, you need to consider whether there is dust, and whether the medium is granular or powdery.
Dielectric constant:
The dielectric constant of the medium directly affects the reflectivity of the radar wave, thus affecting the measurement accuracy. For low dielectric constant media, you may need to choose a specific radar level meter.

Third, consider the environmental factors

Temperature and pressure: determine the minimum and maximum temperature of the medium, as well as the minimum and maximum pressure. Select the radar level meter with the ability to adapt to these environmental conditions, such as the choice of corrosion and explosion-proof characteristics of the radar level meter.
Corrosivity: If the medium is corrosive, you need to consider the material and anti-corrosion properties of the radar level meter. At the same time, if the medium is stored in the tank, you also need to know the material of the tank and whether there is a corrosion-resistant lining.
Working environment: to determine the working environment of the radar level meter, such as open pools, pools with covers, horizontal tanks, vertical tanks, spherical tanks, etc., and whether the tank through atmospheric pressure.

Fourth, consider the installation and maintenance

Installation: The radar level meter can be installed on the top, side or bottom of the level container. Selection should consider the shape, size and installation location of the level container in order to choose the appropriate installation method and equipment.
Ease of maintenance: Consider the ease of maintenance and calibration needs of the radar level meter. Priority should be given to those products with self-diagnostic function and modularized design, so as to facilitate rapid fault location and maintenance and replacement.

V. Other considerations

Form of power supply: determine the radar level meter’s working power supply, whether it is DC 24VDC or AC 220VAC.
Output Signal: Determine the type of output signal required, such as 4-20mA current output, 485 communication output, and whether relay output is required.
Special requirements: according to the actual needs of the consideration of whether the need for anti-corrosion, explosion-proof function, as well as the choice of split-type or integrated radar level meter.

Sixth, comprehensive assessment and selection

After clarifying all the above factors, you can comprehensively evaluate different models and specifications of the radar level meter, and select the most suitable equipment for specific application requirements.

In summary, the selection of a radar level meter is a complex but necessary process that requires consideration of several aspects. By carefully evaluating and comparing different options, you can ensure that the selected equipment will meet the actual needs and operate stably.
