Liquid turbine flowmeter is a commonly used flow measurement instrument that can be used to measure the flow rate of various liquid media. For kinematic viscosity liquids less than 5X10-6 ㎡/s, liquid turbine flow meters have stable and accurate measurement capabilities. In this case, the liquid turbine flowmeter can be directly used to measure liquid flow and obtain more accurate measurement results.
However, for values greater than 5 × The measurement accuracy of liquid turbine flow meters will be affected to a certain extent by the kinematic viscosity of 10-6 ㎡/s. In this case, it is necessary to calibrate the liquid turbine flowmeter in order to obtain more accurate measurement results. Real liquid calibration refers to the calibration of a liquid turbine flowmeter with a known flow rate during actual flow measurement, in order to obtain the actual measurement accuracy of the liquid turbine flowmeter.
After real liquid calibration, the liquid turbine flowmeter can accurately measure kinematic viscosity greater than 5X10-6 ㎡/s with high measurement accuracy and stability. Therefore, liquid turbine flow meters have important application value in measuring the flow rate of viscous liquid media.
In summary, the liquid turbine flowmeter can stably and accurately measure the flow rate of liquids with kinematic viscosity less than 5X10-6 ㎡/s. For kinematic viscosity greater than 5X10-6 ㎡/s, using a liquid turbine flowmeter can obtain more accurate measurement results after actual liquid calibration. Liquid turbine flow meters have broad application prospects in flow measurement of viscous liquid media.
