1. Advantages and disadvantages of Smith scraper flowmeter
Smith scraper flowmeter (Positive Displacement RotaryVane Meter) is composed of a scraper measuring chamber and a double-layer shell under pressure, which can maintain the factory processing accuracy in working state and ensure that the product measurement accuracy does not change with environmental changes. The straight through shell and rotating scraper ensure a large drainage volume, and are widely used in inventory control and settlement of important trade occasions such as crude oil, finished oil, solvents, chemicals, paints, fertilizers, and food. Feature ■ Excellent accuracy - Following the Rotary Vane principle, with a specially designed instrument measuring chamber, the pressure difference between the inlet and outlet is minimized across the measuring chamber, and the medium flow is optimized through the instrument, ensuring instrument accuracy. Extremely low pushing pressure - The latest flow path design provides extremely low pushing pressure. ■ Extremely high instrument repeatability - instrument repeatability reaches 0.05%. ■ Extremely long service life - The instrument adopts low friction ball bearings and a fixed path cam bracket, which enables the scraper to operate accurately according to the predetermined trajectory, ensuring long-term service life.
2. May I ask how to translate "vortex flowmeter" in English?
Vortex flowmeter: positive displacement (PD) flowmeter. Translation of other flowmeters for reference: Electromagnetic flowmeter: Electromagnetic flowmeter, Coriolis mass flowmeter: Coriolis mass flowmeter. Open channel flowmeter: Open channel flowmeter. Orifice plate flowmeter. Rotary flowmeter: Rotameter. Turbine
