Under what conditions will turbine flowmeter deviate

Turbine flowmeter It is a kind of fine flow measurement surface, which can be used to measure the flow and total amount of liquid together with the corresponding flow totalizer. However, some customers have reported that turbine flowmeter sometimes has errors in the measurement process, so what is the cause? Here's a simple analysis.
If the liquid in the pipe is not full, it may be due to the lack of back pressure or the poor orientation of flow sensor equipment, which leads to the liquid in the measuring pipe not full, and the slow movement will be reflected differently due to not being full of liquid.
If a small amount of gas in the water pipe is stratified flow or wavy flow, it is reflected as error addition, that is, the flow measurement value is not consistent with the practice value; if the activity is bubble flow or plug flow, in addition to the measured value does not match the practice value, the gas phase will appear to shake due to the instantaneous concealment of the electrode surface; if the gas part of the flow section increases in the stratification activity of the pipeline, that is, the liquid is not When the level of the full tube increases, the output sloshing will also appear. If the liquid level is below the electrode due to the serious situation of liquid under the pipe, the appearance of output over full degree will appear.
It is also possible that the liquid measured by the turbine flowmeter contains powder, particles or fiber and other solids, which will result in: slurry noise; electrode surface smear; conductive or insulation accumulation layer covering electrode or fabric; fabric is worn or covered by accumulation, and flow section volume is reduced.
After the above description, we should know how to find the measurement error of turbine flowmeter. Therefore, we only need to find out the cause of turbine flowmeter error, then we can avoid the inconvenience in use.

The above is the introduction of Shanghai Cixi on the turbine flowmeter under what conditions the measurement deviation will occur. I hope it can help you. If you still have relevant product problems, you can call the page for consultation! The company provides 24-hour service!
