Description
technical field [0001] The present invention relates to the technical field of fluid measuring equipment, and more specifically, relates to a flow velocity measuring device. Background technique [0002] The flow rate measuring device is mainly used for measuring the flow rate of gas and liquid, and most of the flow rate measuring devices in the prior art are mechanical rotary measuring devices. The measurement principle of this flow velocity measuring device is to obtain the flow velocity by measuring the rotation velocity of the intermediate rotor. [0003] However, this kind of mechanical rotary flow rate measurement device needs to rely on the rotating pair to work, there is a certain friction, and a certain starting flow rate is required, and it is generally not suitable for low flow rate measurement occasions. Moreover, the flow direction lacks accurate measurement, and it is mainly used for flow velocity measurement on a two-dimensional plane, and its application ran...
