Anemometer – used for measuring pulverized coal in coal-fired boilers
Thread Content
When using transmitters to measure the velocity of coal powder, it is common for the pressure guide tubes of these transmitters to become blocked. Do you have any good solutions for this issue? Is adding backflow prevention a good approach?
It is recommended to use a solid dust flow meter; if there are specific requirements, they can be stated. :lol
Backblowing is one method; in catalytic cracking for oil refining, the density and volume of the fluidized catalyst bed are determined by measuring the differential pressure resulting from backblowing

However, foreign products are relatively expensive, and if they break down, there is no one available to repair them. The principle is based on the physical effects of the electrostatic charges of solid particles. Two sensors spaced 42 MM apart detect the static electricity of coal powder; over time, a time difference appears between the waveforms of these two sensors, and by analyzing this time difference, the speed of the coal powder can be determined. Our company develops coal powder and slurry velocity meters through independent research by several doctoral professors from Huazhong University of Science and Technology. Thermoelectric and DYNA speedometer products can also be repaired.
