[0002] The pulverized coal anemometer is a special application of an insertion type vortex street flowmeter. The vortex street flowmeter is a volumetric flowmeter that measures the volumetric flow rate, standard volumetric flow rate, or mass flow rate of gases, steam, or liquids based on the Karman vortex street principle. It is mainly used for measuring the flow rate of fluid media in industrial pipelines, such as various media like gases, liquids, and steam.

[0003] When the insertion type vortex flowmeter needs to measure the pulverized coal wind speed, usually common media such as air and water are replaced with pulverized coal. The insertion rod of the pulverized coal anemometer is inserted into the pulverized coal to measure the wind speed of the pulverized coal, and the measurement data can be obtained through the display screen in the meter head.

[0004] The inventor found the following problems in the process of implementing the present utility model in the prior art: 1. When the medium of the pulverized coal anemometer is replaced with pulverized coal, due to the friction generated during measurement when the insertion rod is in the pulverized coal, the wear degree of the insertion rod and the sensor when used in pulverized coal is higher than that in other media, affecting the service life of the pulverized coal anemometer; 2. Most common pulverized coal anemometers are of an integral structure. When some components are damaged, the whole needs to be replaced, resulting in an increase in the maintenance cost of the pulverized coal anemometer and being unfavorable for the use of the pulverized coal anemometer.
