It was found on-site that the accuracy of flow meters used for measuring water flow into open containers decreases when the flow rate is too high. Why is this? For example, in the case of mass flow meters installed on loading nozzles, or electromagnetic flow meters used to add water into open storage tanks from above the tank
Because each type of flow meter has a velocity range that ensures its measurement accuracy.
I don’t quite understand. Generally, for flow meters based on velocity, the measurement accuracy decreases as the flow rate drops, to the point where no measurement is possible; isn’t a higher flow rate something positive?
It’s normal. If the flow rate is too high, exceeding the range for which the flow meter is designed, accurate measurement becomes impossible (in some cases, it may not be possible to measure at all, and the meter could even get damaged) ； Flowmeters are calibrated within their applicable flow rate range (that is, accuracy is guaranteed within their specified flow range); accuracy is of course not guaranteed when operating above that range.
