Industrial dust flowmeter is mainly suitable for online monitoring of dust concentration in gas-solid two-phase flow, covering dust removal systems and process pipelines in industries such as power, metallurgy, building materials, and chemical engineering. Applicable industries and working conditions: Power industry: Monitoring of dust concentration at the inlet and outlet of electric dust collectors in coal-fired power plants and in ash conveying pipelines, used to optimize dust removal efficiency and prevent pipeline blockage. Metallurgical industry: Dust monitoring of blast furnace gas dust removal, converter flue gas, sintering machine tail gas, with a concentration range usually ranging from 5-200g/m ³. Building materials industry: Monitoring of dust in rotary kiln tail gas, raw material mill/coal mill outlet, grate cooler exhaust gas, with a maximum working temperature of 400 ℃. Chemical industry: Measurement of dust flow in fluidized bed reactors and pneumatic conveying systems, requiring explosion-proof certification (Ex d IIC T6). 2. Technical type: Suitable for dry dust with particle size of 0.1-100 μ m, with a measurement range of 0.01-1000mg/m ³ and an accuracy of ± 2%. FS light scattering type: for 0.1-10 μ m fine particles have a sensitive response and are suitable for concentrations

ranging from 1 μ g/m ³ to 10g/m ³. Regular cleaning of the optical window is required Radiation absorption type: used for environmental emission monitoring, with a measurement accuracy of ± 0.5 μ g/m ³ (requiring regular replacement of the radiation source). Capacitive type: suitable for high concentration dust (up to 1000g/m ³), but susceptible to changes in material dielectric constant Key selection parameters Pipeline size: DN80-DN3000 standard flange interface, special sizes require customization Process conditions: pressure range -0.1-2.5MPa, temperature -40-450 ℃ (high temperature type can reach 800 ℃) Dust characteristics: particle size distribution, humidity (recommended<30%), conductivity, and corrosiveness need to be clearly defined Output signal: 4-20mA analog+RS485 Modbus communication, some support direct display of dust concentration mg/m ³ 4. Installation precautions Installation position: upstream ≥ 6D from the bend/valve, downstream ≥ 3D (D is the pipe diameter), vertical pipeline preferred flow section from bottom to top Protection level: IP65 required for outdoor installation Above protection, explosion-proof area requirements, explosion-proof shell calibration requirements: zero/range calibration is required for the first installation, and standard dust should be used for comparison and verification every 6 months thereafter (note: the above technical data is based on the 2024 mainstream manufacturer product manual, and the specific selection needs to be confirmed according to the on-site working conditions)
