1. Overview of anti-corrosion guided wave radar level gauge products:

The anti-corrosion guided wave radar level gauge is a high-tech product that uses microwave technology to detect material levels. This level gauge utilizes microwave technology, which has good penetration and strong adaptability to harsh environments and tested materials. It utilizes radar principles, digital signal processing technology, and fast Fourier transform (FFT) technology. Adopting continuous intermittent measurement, it can measure the level of liquid and solid (block, powder) materials, and has the characteristics of long distance measurement and high accuracy

The anti-corrosion guided wave radar level gauge has the advantages of low maintenance, high performance, high accuracy, high reliability, and long service life. Compared with contact instruments such as capacitors and heavy hammers, it has unparalleled advantages. The transmission of microwave signals is not affected by the atmosphere, so it can meet the requirements of harsh environments such as volatile gases, high temperature, high pressure, steam, vacuum, and high dust during the process. This product is suitable for harsh environments such as high temperature, high pressure, vacuum, steam, high dust, and volatile gases. Continuous measurements can be taken for different material levels. The main technical indicators of this instrument reach or exceed similar products at home and abroad, and it is easy to install and debug. It can be used as a single unit or in a network, and can be widely used in industries such as metallurgy, building materials, energy, petrochemicals, water conservancy, and grain.

3. Instructions for using anti-corrosion guided wave radar level gauge:

Measurement principle

The anti-corrosion guided wave radar level gauge is a measuring instrument based on the time travel principle. The radar wave travels at the speed of light, and the running time can be converted into a level signal through electronic components. The probe emits high-frequency pulses and propagates along the cable. When the pulses encounter the surface of the material, they are reflected back and received by the receiver inside the instrument, which converts the distance signal into a level signal.

Input

The reflected pulse signal is transmitted along the cable to the electronic circuit of the instrument, and the microprocessor processes and recognizes this signal

The echo generated by microwave pulses on the surface of the material. The correct recognition of echo signals is completed by intelligent software, and the distance from the material list is

The distance D of the surface is proportional to the time travel T of the pulse: D=C × T/2, where C is the speed of light

Since the distance E of the empty tank is known, the level L is: L=E-D

Output

By inputting the empty tank height E (=zero), full tank height F (=full range), and some application parameters, it should be set

Use parameters to automatically adapt the instrument to the measurement environment. Corresponding to 4-20mA output.

Measurement range

F - Measurement Range

E - Empty tank distance

B - Top blind spot

K - Small distance from probe to tank wall

The top blind spot refers to the small distance between the high material surface of the material and the measurement reference point.

The bottom blind spot refers to a distance near the bottom of the cable that cannot be measured.

The effective measurement distance is between the top blind spot and the bottom blind spot.
