Microwave coal injection on-line monitor-HR-WDM

HR-WDM type microwave plugging meter, developed and produced by our company, and obtained the appearance patent and utility model patent, widely used in metallurgy, power generation, cement and other industries of gas-solid two-phase flow air-powder ratio online measurement.

Main application: Widely used in metallurgy, power generation, cement and other industries, typical used in blast furnace coal injection system.

Working principle

Based on the principle of microwave Doppler, the concentration of pulverized coal and the situation of pipe plugging were monitored. In the process of transmitting and receiving microwave, the emitted microwave passes through the measured medium and causes loss, and the loss is proportional to the measured medium concentration. Due to the velocity of the measured medium, there will be a Doppler shift between the transmitted wave and the received wave, and the greater the microwave loss, the higher the concentration of pulverized coal. Therefore, the flow rate of the medium is calculated, and the influence of the flow rate on the concentration is compensated automatically.

Product characteristics

High measurement sensitivity, rapid response, stable output;

Non-contact measurement, long service life, safe and reliable;

Through Doppler frequency shift, the influence of flow rate on concentration is automatically supplemented.

The new model adopts imported ARM chip and adopts digital signal algorithm compensation to ensure data stability;

Abandon the traditional dip knob adjustment, using handheld adjustment, efficient and convenient, user-friendly interaction;

4~20mA and switching signal output, for users to choose;
