The extended version of the dog days is about to open tomorrow, so how can the vortex flowmeter check the fault by observing the waveform method for the attack of the dog days?

  On July 16, the precipitation accompanies the fall, and the 40-day dog days officially begin. The dog days are about to strike. For instrument people, even the high temperature weather will not stop us from the road of development. So let's take a look at how the vortex flowmeter checks the fault by observing the waveform method?

  Sometimes there are some problems when the vortex flowmeter is used. In order to find the problem as soon as possible, we have summarized some methods to find it, as follows:

  1. The equipment replacement method does not need to change the circuit of the vortex street, replace some electronic components that you think may be damaged, and observe how the cause of the failure disappears after the replacement. However, when the flowmeter is overhauled, it is recommended to use the same printed circuit board or electronic components to temporarily replace the problematic part of the flowmeter, and do not disassemble the instrument in the circuit to observe its influence on the fault code.

  2. Observing the waveform method can use an electronic oscilloscope to observe the waveform and amplitude of the input and output of the amplified signal at the input end, and judge the problem of the vortex flowmeter according to the obtained parameters. It is also to observe the current waveform of the flowmeter with a spectrum analyzer, observe the shape of the waveform, and compare it with the normal waveform to check for faults.

  3. The scope of application of the touch test method has been shown in the vortex flowmeter. The touch test method is to apply an electromagnetic signal to the corona circuit, observe the response of the circuit, and determine the location of the circuit at the fault point.

  The above has introduced the vortex flowmeter in use, we can use the above methods to find the problem. If you have other ideas or comments that need to be supplemented, please feel free to call or online to inquire with the editor to learn more about flowmeters, all in Weihai Kunke Flow Meter Co., Ltd. Of course, here, the editor will also Warmly remind everyone that the weather is hot, everyone should pay attention to heatstroke prevention, and try to work as close as possible to the outside for too long. The next issue will be more exciting.
