Advantages and disadvantages of Smith scraper flowmeter
Features - excellent accuracy -- according to the Rotary Vane principle, special design and metering chamber, the entrance and exit of the pressure difference across the room to minimize the measurement, and the medium flow through the instrument is optimized to ensure the accuracy of the instrument.
Smith (Positive Displacement RotaryVane Meter scraper flowmeter) is composed of the scraper metering chamber and the pressure casing double shell combination, can keep the factory processing precision in working condition, ensure the accuracy of measurement products with environmental change. Through the shell and the rotating scraper to ensure a great deal of liquid discharge, widely used in crude oil, refined oil, solvents, chemicals, paint, fertilizer, food and other important trading occasions of inventory control and settlement.
The design of flow path - low pressure push - the most model provides very low driving pressure.The instrument repeatability - instrument repeatability - high up to 0.05%.The use of life - long instrument with low friction ball bearing and the cam bracket fixed path, the scraper accurately according to a predetermined track operation, to ensure the long-term service.
