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.

Why does Rosemounts vortex flowmeter not display instantaneous flow rate, but display cumulative flow rate? _Baidu ...
Are you referring to the screen not displaying? The instrument can be displayed through parameter settings. If the instantaneous flow is zero, but the cumulative flow continues to accumulate, it may be due to a small flow cutoff. In this case, the instrument will filter out very low flow signals to avoid inaccurate instantaneous flow caused by signal interference. There is no need to worry too much about normal signal interference, as there is no actual time record and the accumulated traffic can only be used as reference data. When the instantaneous flow rate is not displayed, the parameter settings of the instrument can be checked to ensure its correct configuration. If the settings are correct but the problem still appears, it is recommended to check the connection and power status of the instrument. Sometimes, instrument display issues may be related to hardware or software failures. If the problem persists, it is best to contact the manufacturer or professional technicians for further diagnosis. In practical applications, the display of instantaneous flow rate and cumulative flow rate of vortex flowmeter may be affected by various factors. Signal interference is one of the common causes, especially in industrial environments. In order to ensure the accuracy of data rows, the instrument usually sets a threshold. When the instantaneous flow rate is below this threshold, the system may automatically cut off this part of the data and only display the effective flow rate. This helps to reduce erroneous data caused by interference. For the situation where the
