Background

Spring flowmeter belongs to flow measurement technical field. The flowmeter comprises a cylindrical pipe body, a conical shell, a floating piece, a spring and the like, wherein the spring is arranged in the pipe body. A spring flowmeter is a variable-area instrument, and a conical measuring body is arranged in a floating part and forms a conical opening with a body. When the fluid passes through the flow meter, pressure difference is formed at two ends of the sharp edge measuring hole, so that the floating part moves towards the direction of the compression spring. The displacement of the float is precisely proportional to the flow (velocity). The flowmeter is suitable for detecting various liquids and gases. The spring flowmeter utilizes the principle that the elastic deformation of a spring is in direct proportion to the impulse force generated by the flow (flow velocity), converts the elastic deformation of the spring into the flow velocity through the impulse force, and calculates the flow by multiplying the flow velocity by the sectional area of a pipeline, thereby overcoming the defects of the traditional flowmeter and achieving the purposes of accurate and timely measurement, small interference and convenient carrying.
