Smart radar level gauge analyzes echoes with latest micro-processing technology and debugging software
2012-4-24 8:45:31

应用方式:应用于油田石化、钢铁、冶金、电力、水泥、煤炭、食品及水处理等许多行业。 Intelligent radar level meter application method: used in many industries such as oilfield petrochemical, steel, metallurgy, power, cement, coal, food and water treatment. So if you want to do it, you can start from these industries! Detailed description of intelligent radar level meter: extremely short microwave pulses with very low transmission energy are transmitted and received through the antenna system. Radar waves travel at the speed of light. The running time can be converted into a level signal by electronic components. A special time extension method ensures stable and accurate measurements in a very short time. Even if the working conditions are more complicated, there are false echoes. The latest micro-processing technology and debugging software can accurately analyze the level echoes.

都可以进行测量,功效显著。 The intelligent radar level meter can measure under harsh conditions such as toxic media, corrosive media, solid, liquid, dusty, and slurry media, and has significant effects. It mainly has the following measurement characteristics: 1. It has the function of suppressing the interference echo, for example, the interference echo caused by the joint in the beam range and the interference echo caused by the noise of the input or output can be automatically controlled by the internal fuzzy logic. Suppress. 2. Continuous and accurate measurement, not affected by the environment due to the characteristics of electromagnetic waves. Therefore, its measurement applications are relatively wide. The probe of the radar level gauge has no contact with the surface of the medium, which is a non-contact measurement. It can accurately and quickly measure different media. The probe is hardly affected by temperature, pressure, gas, etc. (the effect is only 0.018% at 500 ° C and 0.8% at 50bar). 3. Accurate, safe and energy saving. The radar level gauge can measure under vacuum and pressure, and it is accurate, safe and reliable. It can be applied to various occasions without any restrictions. The radar level gauge uses materials that are chemically and mechanically stable, and the materials can be recycled, which is highly environmentally friendly. 4. Convenient maintenance, simple operation, radar level gauge with fault alarm and self-diagnostic functions. Analyze the fault according to the error code prompted by the operation display module, and determine the fault in time to eliminate it, making maintenance and calibration more convenient and accurate, and ensuring the normal operation of the instrument. 5. It has a wide range of applications. It can measure almost all media. From the shape of the tank body, the radar level gauge can measure the liquid level of spherical tanks, horizontal tanks, cylindrical tanks, cylindrical cone tanks, etc .; In terms of physical function, the liquid level in the storage tank, buffer tank, microwave tube, and bypass tube can be measured; from the measured medium, liquid, particles, slurry, etc. can be measured. 6. No maintenance, high availability, almost no interference with the microwave, and no direct contact with the measurement medium, can be used in almost all occasions, such as vacuum measurement, liquid level measurement or material level measurement. Due to the use of advanced materials, it is durable to extremely complicated chemical and physical conditions, and it can provide accurate, reliable, long-term stable analog or digital level signals.
