Description

technical field [0001] The invention relates to a device for measuring gas velocity and flow. Background technique [0002] At present, it is necessary to measure the flow rate and flow rate of gas released by substances in many fields, such as measuring the hydrogen release rate and amount of hydrogen storage alloy powder, and measuring the rate and amount of gas released by the hydrolysis of a certain substance; these measurements are generally They are all devices that use a simple gas generation-drainage method to collect gas. By recording the gas production at different times, the gas release rate and release amount of this substance can be calculated. This method is time-consuming and labor-intensive, and there are large human errors in time recording and gas production reading, resulting in inaccurate data; due to the inability to accurately control the reaction temperature of the substance, there are also great limitations in measurement. Devices for measuring the r...
