Which parameter of the melt pump can indicate whether there is material in the pipeline?

I would like to ask the experts: when the material flow in the pipeline comes to an end, which parameter of the melt pump can be used to detect this? Thank you!
The flow rate and pressure of the melt pump are key parameters that indicate whether there is material in the pipeline. When the material flow stops, the flow rate drops to near zero, and the pressure also experiences a significant change. .
When the medium is gone, the outlet pressure, flow rate, and current will decrease – this is the most obvious effect. Additionally, the vibration and abnormal noises of the pump also change significantly.
