Accuracy issues with turbine flowmeters and vortex flowmeters
Thread Content
Under the same conditions, that is, at the same measurement point, which one has higher accuracy, the turbine flow meter or the vortex street flow meter? Which one is more expensive in price?
It’s not easy to compare. There are too many exceptions. Generally, turbines can achieve high precision, but they have one drawback – the range within which such precision can be obtained is relatively narrow. Some high-precision turbines are often specialized, such as paraffin flow meters... In this case, both the price and cost-effectiveness are relatively high ； The electrical components of turbines vary greatly in structure; they feature simple pulse outputs with few electronic components, which allows for significant cost savings compared to the electrical components of vortex flow meters ； …… .
Under the same conditions, it’s hard to say. Turbines and vortex street sensors with the same precision can also exhibit deviations under different media and processing conditions.
