What problems have been encountered with turbine flowmeters in practical use?
Thread Content
Turbine flowmeters are widely used in actual production. What problems have been encountered during their use? Let’s all discuss which aspects reflect advantages, and which ones represent disadvantages or taboos.
The most common issue is that debris gets stuck
The topic proposed is too general and lacks specificity; it is suggested that you list specific questions for everyone to discuss and grow together

In our factory, a new vortex flow meter has just been put into use. Even when there is no flow of fluid in the pipeline, it still shows a flow rate of 4%. To meet the process requirements, we had to remove this meter; I suspect that it is related to pipeline vibration
The turbine flowmeters in our company are Aitoli flowmeters. After one year of use, two were broken by thunder.
It’s quite common here for thunder to cause damage. Another issue is account locking, which is the most frequent problem; other issues aren’t that serious. The accuracy is still guaranteed
It’s best to add a filter in front of the flow meter as well.
Wasn’t a surge protector installed on the instrument on site?
Thank you all for your help. I’ve identified the main issues with the turbine flowmeter; it seems that installing a filter is very important, and lightning protection considerations need to take into account both local conditions and the characteristics of the device itself
The working principle of a vortex flow meter is different from that of a turbine flow meter. A vortex flow meter generates signals as fluid passes by a vibrator; therefore, it is not suitable for use in situations where the pipeline experiences vibrations. A turbine flow meter, on the other hand, generates signals based on the rotation of its impeller, which makes it more stable. In trade measurement applications, turbine flow meters or rotameters are generally used
