Why can the range of volumetric flow rate measured by a vortex flow meter include negative values? ? Some professional knowledge about vortex flowmeters can be added. . . Thank you
This is probably related to the characteristics of the sensing element in the vortex flow meter you are using. Please explain in detail the principle behind the sensing element of your vortex flowmeter, and also talk about the properties of your fluid.
It utilizes the principle of alternating charges generated upon impact by vortices, thanks to piezoelectric crystal elements. It is mainly used to measure gases.
No way, vortex flow meters cannot measure negative flow rates
The poster’s question is odd – vortex flow meters are unable to measure flow rates below 5 m/s (for gases); in such cases the reading should be 0, so there’s no way a negative value can occur. Unless you have installed a low-quality, cheap watch
There is no concept of negative traffic values; I don’t know where that idea comes from. Does it indicate the direction of flow?
Can’t the measurement range be negative? Where did the original poster see it? Could they send a picture for everyone to see?
With this question, is the poster asking whether negative values appear in the measurements, or is it about the measurement range of the flow meter? The measurement range does not include negative values. If a negative value appears in the measurement, it is usually due to a faulty gauge; if the negative value is very small, it might be zero drift.
Vortex flowmeters of different sizes have varying flow range capabilities. For example: The flow range of a DN100 vortex flow meter is 150–1700 m3/h. The smaller the diameter, the lower the lower limit, but negative values will not be measured.
How is it possible to measure negative values? That can’t be!
