Is it accurate to measure RO water with a vortex flow meter?

Project Overview

RO water refers to pure water that has been treated by a reverse osmosis membrane. Its water quality is relatively pure and has no impurities. This feature is a fatal shortcoming (non-conductive) for electromagnetic flowmeters, which are commonly used for liquids. However, the vortex flowmeter does not have any requirements on whether the liquid is conductive or not, so it is suitable to use a vortex flowmeter to measure RO water.

The accuracy of a vortex flowmeter is usually between ±1% and ±2% of the full scale range (R) for liquid media, and its repeatability is generally between 0.2% and 0.5% . RO water (reverse osmosis water) is a relatively pure liquid with relatively stable physical properties and does not contain impurities such as suspended solids and organic matter. This is beneficial to improving the accuracy of measurement because the instrument coefficient of the vortex flowmeter is not affected by the measurement. significant influence on the physical properties of the medium.

Therefore, the accuracy of measuring RO water using a vortex flowmeter is relatively high, as long as the appropriate model is selected within the appropriate range and installed according to the correct installation requirements to avoid pipe vibration, By properly aligning the flow direction and other factors that interfere with measurement, you can expect more accurate measurement results. However, the specific application accuracy may also be affected by the actual working conditions, maintenance conditions, and the quality and calibration status of the instrument itself. Therefore, in actual use, it may be necessary to refer to the specifications of the specific vortex flowmeter or conduct on-site verification to confirm the final accuracy. measurement accuracy.
