It is unarguably true that the use of flow measuring devices is significant in many industries. Hence, these devices measure the flow of liquids in the pipes and give output. However, in many circumstances, the working of the flow meters can become affected due to several factors. Due to having many substances in the liquids or gases, the measurement results can vary or show inaccuracy. The inaccurate results can lead to wrong output regarding the overall production, and it can cause an enormous increase in costs and waste many manufacturing resources. So, to overcome such situations, it is essential to use high-quality flow measuring tools.
Possible causes of inaccurate results by the flow meter
Well, there may be multiple factors that could contribute to the wrong measurement of the meters. But mainly, there are common problems that can hinder the results of meters regarding liquids flowing inside.
The groundwater usually contains crystallized metallic ions and can attach to the inner walls of the pipes, and they are generally composed of magnesium, calcium, and sodium. The buildup of too much can obstruct the flow of liquids that could affect the working of flow meters.
Change in velocity
The variation in the velocity of fluid running in the pipes can also result in measuring errors.
However, the problem that occurs in the measuring efficiency of these meters can be eliminated, and proper maintenance and cleaning of pipes can eradicate these causes. But, some specialized types of flow meters can reduce the chances of measurement errors.
When it comes to reducing measurement errors, many experts recommend the use of this flow meter.
Why are these meters good?
Scaling is the act of building up clogs inside the fluid that can attach to the inner side of the pipes. It can be due to metallic ions that can obstruct the flow path of liquid. The meters with mechanical working could lead to inaccurate measurements. Hence, the fragments can build up by breaking off from the mechanical components of meters. But, this is not the situation in the case of electromagnetic meters. They can sense the voltage that has been generated inside the flow line and can produce accurate results.
Accumulation of foreign substances in the flow pipe can also obstruct the flow and lead to the wrong measuring of the liquid. But, when you install the electromagnetic flow meter, it can lead to reliable results. These meters have a free-flowing structure, and thus the chances of accumulating substances are less. Using an electromagnetic flow sensor with non-wetted electrodes can lower the effect of foreign particles. Therefore, it can reduce measurement errors to derive accurate results.
Slime is a living microorganism that can also obstruct flow that leads to the wrong measurement. Electromagnetic meters do not affect slime as they also have electrical conductivity. So, the detection of flow measurement cannot be obstructed and remain correct.
The use of digital electromagnetic flow meters is considerably appreciated in modern industries. The reason is clear as these meters have higher accuracy than traditional meters. Moreover, they are free of moving parts, and use is also convenient.
