Hi Team,
Currently, the customer is testing the adaptability of the flow meter to pipes made of different materials. The transducer installation method used is a "V" type installation, as shown in the figure below:
When the device is installed on a PVC pipe, it seems that two distinctive lobes can be seen on USS GUI. When the Gap between pulse start and ADC capture parameter is 40, the waveform is as follows:
When the Gap between pulse start and ADC capture parameter is 80, the waveform is as follows:
When the Gap between pulse start and ADC capture parameter is 60, we can clearly see the boundary between the two lobes:
However, only when the Gap between pulse start and ADC capture parameter is 80, the displayed lobe can be used for flow calculation correctly, that is, the second lobe can be used for flow calculation. The signal strength of the first lobe seems to be low, and GUI will report an error and cannot perform calculations.
The customer's current problem is that when they put the measuring device on the stainless steel pipe, there is only one wave lobe seen by GUI. When the Gap between pulse start and ADC capture parameter is 40, the waveform is:
This waveform cannot be used for flow calculation and errors will be reported frequently.
But when the Gap between pulse start and ADC capture parameter is 80, there is no second lobe like the PVC pipe, but a bunch of messy signals, as shown in the figure below:
Therefore, the device cannot perform flow measurement on stainless steel pipe. What may be the cause of this problem and what are the solutions?
