Who can help me explain the steam vortex flowmeter small flow removal mean?
The user's statement is wrong, small flow frequency resection, such as the actual frequency of 110 than the resection frequency value of 10, shows the normal frequency of 110, the flow is the actual flow; only less than 10 when the flow rate is 0
Small flow is generally set around the limit of vortex range, for because of vibration or other interferences generated by resection of vortex sensor non normal signal, but if you set a small flow, the interference signal or the calculated production flow is greater than the cutoff value, then the traffic will be accumulated
Vortex street small flow resection is that the frequency or instantaneous flow is less than a certain value, no longer accumulated.Small flow resection is usually divided into frequency division settings (such as setting 80HZ below resection) or flow range setting resection (such as setting full flow 5% below resection)
