Smith2012 Series PD scraper is displacement flow meter (Positive Displacement Rotary Vane Meter) is made up of a scraper, metrology room and double-shell casing pressure which can maintain the factory work machining accuracy to ensure that the measurement accuracy of products could not change as the environment. Shell and rotate through the scraper guarantee a great liquid discharge volume, widely used in crude oil, finished oil, solvents, chemicals, paints, fertilizers, food, and other important occasions trade inventory control and clearing. Features Excellent accuracy — Smith2012 Series PD flow meter Rotary Vane follow the principle of rotation, and the special flow meter for measuring Room is making entrances and exits to minimize the pressure difference across the measuring room, and through the medium of mobile flow meter makes best. Ensure accuracy of the flow meter. * Promote the low pressure — the latest model of a very low flow path design of the impetus pressure. * Flow Meter highly repetitive – flow meter repeatability of 0.05%. * An extremely long service life – flow meter uses low friction ball bearings and cam fixed path trestle, making accurate and track operation according to the scraper, thus ensuring the long-term life.
