Why does the vortex flowmeter display normal cumulative flow and abnormal instantaneous flow?
A vortex flowmeter is used to measure the flow rate of water, which is installed separately. A vortex flowmeter sensor is installed on site to output pulse signals and used in conjunction with a flow integrator.. Installed on site, it was found that the instantaneous flow displayed zero, thinking that the equipment was not started. After inspection, it was found that the equipment was running normally. At the same time, it was found that the cumulative flow value was already accumulating, but the instantaneous flow display was still zero. Under normal operating conditions, the cumulative instantaneous flow value only has the numerical value of the cumulative flow value. This situation is obviously abnormal. Entering the menu of the flow integrator, I found that there is an instantaneous flow filtering function FLTR set to a value of 3. Try changing it to 1, and the result will return to the measurement state. Both the instantaneous flow rate and cumulative flow rate of the flowmeter will be displayed normally. So I checked the manual again and finally understood that the reason why the flow integrator did not display instantaneous flow but displayed cumulative flow was that the flow integrator had a digital filtering function to overcome flow fluctuations, and the display of instantaneous flow did not affect the measurement of cumulative flow. Because the traffic signal is not large, FLTR is set to 3 digits which are too large, resulting in high filtering and slow response, causing the display to not search for potatoes and appearing normal. Change to 1, the filtering effect is low, the response is slightly fast
2. Vortex flowmeter with pressure pipeline component license and special form testing report
Vortex flowmeter with pressure pipeline component license and special form testing report is a product that meets the mandatory requirements of national special equipment and has legal production and quality assurance qualifications.
. The specific explanation is as follows: Pressure Pipeline Component Branch Lead Dipper License (TS Certification). This license is a professional license issued by the State Administration for Market Regulation for special equipment production units, covering design, manufacturing, installation, and other aspects. For vortex flowmeter, the manufacturer must hold this certificate, indicating that it has legal production qualifications and the product meets the safety technical specifications of pressure pipeline components. For example, Qingdao Hesheng Measurement and Control obtained this certification in 2020, and the vortex flowmeter produced by them meets the mandatory national standards in the manufacturing process. The special form inspection report (special equipment supervision and inspection certificate) is issued by the special equipment supervision and inspection agency after inspecting the vortex flowmeter. It is issued for specific products to prove that their performance and safety indicators meet the requirements. This certificate is delivered to the user along with the product as a direct proof
