26G flare antenna radar level meter

1. Product Introduction

The bell-mouth antenna radar level meter is a general-purpose 26GHz high-frequency pulse non-contact intelligent measuring instrument in the field of industrial automation measurement and control, specially designed for continuous monitoring scenarios of liquid levels, material levels, and interfaces in various industrial storage tanks, reactors, buffer tanks, and storage silos. Unlike traditional contact measurement equipment, this instrument uses advanced high-frequency microwave measurement technology paired with a classic high-gain bell-mouth antenna structure. It offers strong beam focusing and excellent signal penetration, easily overcoming complex interference such as on-site steam diffusion, liquid surface foam, fine dust, tank wall condensation, and frequent temperature and pressure fluctuations, achieving contactless, high-precision, and highly stable all-weather automated level monitoring throughout. The entire equipment has no mechanical moving parts, so there are no mechanical wear, jamming, or rust issues. It requires no frequent calibration or manual maintenance, has a long service life, and offers high operational stability. It can be widely adapted to various media such as clean water, sewage, acidic and alkali corrosive liquids, viscous slurries, and granular materials. It is the mainstream standard level measurement device in many industries including petrochemicals, water treatment and environmental protection, thermal power and power, pharmaceuticals, grain and oil food, metallurgy and building materials.

This instrument operates based on the mature and stable principle of high-frequency microwave pulse ranging. It transmits high-frequency electromagnetic signals in a high-precision antenna directionally. These electromagnetic waves can penetrate air, steam, foam, and thin dust without obstruction, precisely reaching the material surface to form stable reflected echoes. The device is equipped with a high-speed intelligent signal processing chip that can quickly capture echo signals and accurately calculate the time difference between microwave transmission and reception. Combined with proprietary algorithms, it converts and outputs precise liquid level and material level height data in real time, effectively avoiding data delays, Issues such as fluctuations and distortion. Compared to traditional ultrasonic level meters, which are easily affected by temperature and airflow, as well as the drawbacks of guided radar that easily seize material, corrode, and require contact with media, bell-mouth radar level meters have smaller measurement blind spots, a wider effective range, and stronger resistance to environmental interference. Their measurement data are unaffected by media density, material viscosity, liquid level fluctuations, or air pressure changes, making them perfectly suited to various complex industrial conditions such as normal temperature, medium high temperature, atmospheric pressure, negative pressure, and medium to high pressure. Their versatility and adaptability far surpass traditional measuring equipment.
