Description
Metal scraper flowmeter is a positive displacement flowmeter used for continuous or intermittent precision measurement of liquid flow through pipelines. It adopts double shell structure, rotor constant speed rotation with smooth operation, no pulsation, low noise, large flow, sand control, high measurement accuracy, long service life and viscosity change adaptability, widely used in petroleum, chemical, light industry, transportation, commercial and other departments, especially suitable for measuring crude oil, residual oil, refined oil, light hydrocarbons and other media transfer and trade settlement measurement. The metal scraper flowmeter can be indicated on site or controlled remotely.
■ Working principle
When the measured liquid enters the flow time, the liquid impacts the scraper, pushes the scraper and the rotor to rotate clockwise along the CAM, and the scraper expands and expands along a certain track with the CAM, and forms an accurate measuring chamber with the rotor, the inner shell, the cover plate, etc., with the continuous rotation of the rotor and the plate, the purpose of measuring the measured medium is achieved.
