How to deal with flow fluctuations of turbine flow meters?

Many people may not be familiar with liquid turbine flow meters, but they play an important role in our lives. For example, when refueling or using tap water, this instrument must be used to measure the flow of liquid. For natural water plants, they need to purchase a large amount of this product, so when using this product, if the flow indication fluctuates greatly, how to solve it? If you want to know, keep reading!

First, regardless of whether the water source is a pulsating flow

When using tap water, I believe most households use it at a constant speed, that is, the tap water flows at a constant speed in the pipes. In this case, there is no pulsating flow, but it cannot be ruled out that some turbine flow meters will be affected by pulsating flow in special occasions, such as when using it to pump raw materials. If the distance between the raw material pump and the flow meter is relatively close, pulsating flow may occur at this time, which will seriously affect the flow meter indication. If you want to solve this problem, you should extend the straight pipe distance between the pump and the flow meter! On the other hand, if the location of the turbine flow meter is too close to the elbow and the valve, in this case, the flow rate may fluctuate when the liquid passes through these two parts, so the location away from the valve and elbow should also be selected during installation, so that the electrical energy can avoid the influence of the turbine flow meter indication!

Secondly, is there any interference in the turbine flow meter?

If it is interfered by various electromagnetic waves or electrical energy, the stability of its indication will also be seriously affected. Therefore, it is necessary to check whether there are various strong interference sources such as frequency converters or motors nearby. The presence of these sources of interference may also cause its indication to fluctuate continuously. At this time, the turbine flow meter is unstable and a grounding wire should be added to the meter. If interference cannot be avoided, the flow meter should be installed away from the source of interference!

Through the introduction and analysis of this article, we can know that for such a turbine flow meter, many people may not know how to solve various faults. For faults with large indication fluctuations, the cause should be found and solved according to the above method. Of course, in addition to these faults, there may also be minor problems such as no display process or display process. When troubleshooting, you should also find out the cause first!
