Vortex flowmeter accuracy + 1%R + 2%FS what does that mean?
Vortex flowmeter is based on the vortex theory of Carmen (Karman), which is mainly used to measure the flow of medium fluid in industrial pipeline, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large measuring range and high accuracy. It is almost unaffected by parameters such as fluid density, pressure, temperature and viscosity when measuring volume of flow.
The accuracy of vortex flowmeter is + 1%R and + 2%FS:The difference between the measured value of the vortex flowmeter and the actual degree is only 1%, and the difference between the full scale value of the flowmeter and the actual full scale value is only 2%.
The mean precision of + 1%R is 1% + of the actual reading. It is a value that varies with the actual reading. The mean value of + 2%FS is 2% + of the full scale and is a stable value. R is the first uppercase letter in English Read, and FS is the abbreviation of English Full SCAL (full scale).
