EmailThe FLW-300 is based on the principle of the ultrasonic time difference method for gas flow rate measurement. The product adopts the innovative structure design of temperature, pressure and flow integration with simple installation and disassembly. It is used for flow rate measurement of boiler flue and chimney flue gas and is particularly suitable in the cases of a short straight pipe section, a low-speed flue of less than 5m/s, and a flue where it is not possible to increase the number of openings.
Time difference method for measurement, high measurement accuracy, good reliability, long-term continuous work;
Good anti-interference, free from temperature and pressure influence on velocity measurement;
Single side flue opening, with no need for straightening, suitable for different flue pipe diameters;
No need to increase the installation platform, reducing installation costs; integrated design, easy maintenance;
Suitable for high dust, high humidity and other harsh environments.
Emission monitoring in coal-fired power plants, waste incineration, cement, iron and steel, glass industry, petrochemical, paper and textile industries.
