1.What is the detectable bubble and particle size range for the flow sensor? What is the indication method? What happens if bubbles or particles are too large?
Within a certain flow range, bubbles with a size equal to or greater than 30% of the tubing inner diameter(ID) can be stably detected. Bubbles can be visually read through the XY-TEK Flowviewer software or via switch alarm output. If bubbles are too large, they will affect flow rate measurement accuracy and repeatability.
2.What is the minimum bubble size that the XY-TEK flow sensor and bubble detector can detect?
The minimum detectable bubble size is 30% of the tubing inner diameter(ID).
3.How does the XY-TEK flow sensor/flow meters indicate bubble detection events?
Bubble detection events can be visually read through the XY-TEK Flowviewer software, or by querying the corresponding address via RS485 communication to check bubble detection status. If the flow sensors / flow meters are equipped with switch outputs, they can obtain bubble detection results by configuring the switch output.
4.How much do bubbles in the liquid will affect measurement accuracy? For example, how will the ultrasonic flow sensor / flow meter react if liquid flow is interrupted by bubbles?

When there are numerous and continuous bubbles in the tubing, the flow sensor flow meter reading will return to 0, and the presence of bubbles will be indicated by circles in the Flowviewer observation interface. By setting the bubble damping time, short-term occasional bubbles passing through the flow sensor can be ignored; only bubbles lasting longer than the stetted value will trigger a bubble alarm.
