Abstract

The invention provides an air flow indicator. The air flow indicator comprises a cylinder body, a flow adjusting mechanism, an impeller, an induction magnetic disc, an electromagnetic inductor, a maincontrol chip and a display, wherein the cylinder body is axially arranged in a penetrating mode, an air inlet is formed in one end of the cylinder body, an air outlet is formed in the other end of the cylinder body, the flow adjusting mechanism is arranged in the cylinder body and is close to the air outlet, the flow adjusting mechanism comprises a valve block and a control assembly, the valve block is arranged in the cylinder body in a pivoted mode and is driven by the control assembly to pivot, and the impeller is arranged in the barrel and is close to the air inlet. The induction magneticdisc and the impeller are linked to form electromagnetic pulses, the electromagnetic inductor collects the electromagnetic pulses and feeds back the electromagnetic pulses to the main control chip, and the display is arranged on the cylinder and displays the air volume calculated by the main control chip. The air flow indicator can be installed on the air pipe in a combined mode, and the flow of air in the air pipe is measured in real time. Meanwhile, the measured flow can be digitally displayed, so that the flow value can be read more visually.

Description

technical field [0001] The invention relates to the technical field of air flow measurement, in particular to an air flow indicator. Background technique [0002] In activities such as industrial production, it is necessary to measure the flow of air to grasp the air supply or exhaust air volume of the air duct. However, the existing air volume indicators can only qualitatively indicate whether the airflow passes through and the relative size of the airflow by means of cloth strips or ribbons, and cannot perform accurate measurement. Therefore, it is necessary to propose a further solution to the above problems. Contents of the invention [0003] The object of the present invention is to provide an air flow indicator to overcome the deficiencies in the prior art. [0004] To achieve the purpose of the above invention, the present invention provides an air flow indicator, which includes: a cylinder, a flow regulating mechanism, an impeller, an induction disk, an electroma...
