HCDAR-63 universal flange radar level gauge

The 26G universal flange radar level gauge outputs 4-20mA/RS485 signals and can measure a maximum distance of up to 70 meters. The horn antenna has been further optimized to add a blowing function. The new microprocessor can perform high-speed signal analysis and processing, and the instrument can measure various solid particles and powders with stability and reliability. The universal flange can be configured to adjust the angle of the material pile to obtain better echo signals.

Overview of Universal Flange Radar Level Gauge Products:

HCDAR-6X electromagnetic waves propagate in space at the speed of light, and when they encounter the surface of the measured medium, some of their energy is reflected back and received by the same antenna. Calculate the distance from the antenna to the surface of the measured medium based on the time interval between two pulses.

Product principle:

The antenna system emits and receives very short, low-energy microwave pulses. Radar waves propagate at the speed of light. The running time can be converted into a level signal through electronic components. A special time extension method can ensure stable and accurate measurements in a very short amount of time. Even if there are false echoes in complex working conditions, the micro processing technology and debugging software can be used to accurately analyze the echoes of material positions.

input

The antenna receives reflected microwave pulses and sends them to the electronic circuit. The microprocessor processes signals and identifies echoes generated by micro pulses on the surface of the material.

Accurate recognition of echo signals can be achieved with millimeter level precision through intelligent software. The distance D from the material surface is proportional to the time interval of the pulse:

D=C*T/2

Among them, C is the speed of light, because the distance E of the empty can,

So, the material/liquid level position L is:

L=E-D

By inputting the empty tank height E (=zero), full tank height F (=full range), and some application parameter settings, the instrument is automatically adapted to the measurement environment.

In the field of industrial process control, accurate level measurement is crucial for ensuring production efficiency and product quality. As an advanced measuring tool, the universal flange radar level gauge is widely used in various liquid level and material level measurements due to its high precision and reliability.

The radar level gauge is based on radar (radio detection and ranging) technology. It measures distance by emitting microwave signals and receiving their reflected waves. When the microwave signal encounters the surface of the material, it will reflect back to the radar sensor. By measuring the round-trip time of the signal, the distance from the material surface to the sensor can be calculated, and the height of the material level can be obtained.

The design of the universal flange is a significant feature of the radar level gauge. This design allows the radar level gauge to be easily installed on various types of containers, whether made of metal or non-metal materials, and whether installed on the top or side. The flexibility of universal flanges greatly simplifies the installation process and reduces erroneous measurements caused by improper installation.

The application of radar level gauges is very extensive. In the chemical industry, it is used to measure the level of corrosive liquids, slurries, or solid particles; In the petrochemical industry, it is used to monitor the oil level in oil tanks; In the water treatment industry, it is used to measure the water level in a pool. In these applications, radar level gauges can provide stable and accurate measurement results, helping operators adjust process parameters in a timely manner, ensuring the continuity and safety of the production process.

The advantage of radar level gauges lies in their non-contact measurement method, which avoids material contamination and equipment wear. In addition, radar level gauges are usually not affected by environmental factors such as temperature, pressure, humidity, dust, etc., making them very suitable for use in harsh industrial environments.

Although radar level gauges have many advantages, there are also some issues to be aware of when using them. For example, the surface characteristics of materials (such as reflectivity) may affect measurement accuracy; Some obstacles inside the container may interfere with the propagation of microwave signals; Extreme temperature conditions may also affect the performance of equipment. Therefore, when selecting and using radar level timing, it is necessary to make appropriate configurations and adjustments based on the specific application environment and material characteristics.

Radar level gauge is an efficient and reliable solution for level measurement. Its universal flange design, non-contact measurement principle, and strong environmental adaptability make it an indispensable tool in industrial process control. Through reasonable selection and correct use, radar level gauges can provide accurate level measurement in various complex industrial applications, helping enterprises optimize production processes, improve product quality and production efficiency.
