What really happens when the flow rate drops below the low flow threshold of a vortex meter?
Does the meter fail to detect low (laminar) flows so that the instrument output falls to zero before the flow stops, or do you continue to get some kind of signal with less accuracy until the flow stops completely? Can you get occassional, random readings from a vortex meter with no flow from vibration in the system?
