Online wind speed measurement system and test method for chemical scene

wind speed, Gas , On line measurement, testing, low speed

When we work in the chemical scene, people should measure the wind speed according to the actual situation of the closed space, and conduct regular detection or continuous monitoring,while there are usually many toxic, harmful, flammable and explosive gases in the closed space in the chemical scene. At present, the on-line measurement technology of wind speed is insufficient at low flow velocity. Specifically, the regularity and signal strength of the vortex train generated by the device are very weak, and the signal can hardly be detected, so the measurement cannot be realized. This measuring system has been provided with bionic convex structure, which has drag reduction effect and can overcome the problem that the speed of gas and solid contact surface is slow and cannot be measured.
