    This volumetric scraper flowmeter is suitable for on-site metering of light oil product , and consists of flow-guiding component, flow sensor, pulse signal generator and intelligent flow display. It features that the profile of inner cavity of its casing with an optimized mathematical model may be correctly designed, and accurately processed by use of computer and numerically controlled machine tool. In addition, the pulse signal generator is a self-locked Hall signal generator which outputs pulse signal for precise calculation. The intelligent flow display has the functions of accumulative metering, single metering, instantaneous flow calculation and pulse counting for realizing on-site tolerance regulation and precision correction. Its advantages include high accuracy, stable operation and low noise.
