Why does the vortex flowmeter display normal cumulative flow and abnormal instantaneous flow?
A vortex flowmeter is installed on site for measuring water flow, using a split installation method. The on-site equipment is running normally, but it was found that the instantaneous flow rate is displayed as zero, while the cumulative flow rate is accumulating normally. This situation is obviously not in line with convention, as under normal operating conditions, the cumulative instantaneous flow rate should be consistent with the cumulative flow rate value. After checking the menu of the flow integrator, it was found that the setting value of the instantaneous flow filtering function FLTR was 3, which caused abnormal display of instantaneous flow. After adjusting this value to 1, the instantaneous flow rate and cumulative flow rate display of the flowmeter returned to normal. After checking the manual, it was found that the flow integrator has a digital filtering function, which is used to overcome flow fluctuations and ensure the accuracy of accumulated flow. When the flow signal is small, setting FLTR to 3 will cause excessive filtering effect and slow response speed, thereby affecting the correct display of instantaneous flow. After adjusting to 1, the filtering effect decreases, the response speed of the anti macro front increases, and the results of the display hood are normal. However, regardless of the setting, it will not affect the accurate measurement of cumulative traffic.

2. Can vortex flowmeters be installed vertically?
Vortex flowmeters can be installed vertically, but some installation points need to be noted.
. Firstly, vortex flowmeters are feasible for vertical installation. However, in order to ensure the accuracy and stability of the measurement, special attention should be paid to the following points:1. Avoid the influence of sediment and bubbles: When installed vertically, ensure that there is no accumulation of sediment or bubbles inside the flowmeter, as these factors may interfere with the measurement accuracy of the flowmeter.
. Chenzai rubber residue may adhere to the measuring electrode of the flowmeter, causing signal distortion; Bubbles may generate false flow signals. 2. Keep the electrode axis horizontal: Although vortex flowmeters can be installed vertically, it is recommended to keep the measuring electrode axis horizontal to better avoid the influence of sediment and bubbles. This can minimize the interference of sediment and bubbles on the measuring electrode, thereby improving the accuracy of the measurement. Interpretation 3: Consider the effects of turbulence and eddies: It should be noted that the measurement of vortex flowmeters, such as the key principle, does not depend on the characteristics of the flow rate. Therefore, if certain turbulence and eddies are generated in the pipeline, as long as these turbulence and eddies occur in the non measurement area, they will not have a direct impact on the measurement. However, in practical applications, it is still advisable to avoid excessive turbulence and eddies as much as possible to ensure the stability of the measurement. In summary, vortex flowmeter
