Leak Status Indication

NO Leak: When the value of the pressure gauge remains unchanged and the flow meter will read zero (ball at bottom of scale), it means that there is no leakage in the system.

Small Leak: When the value of the pressure gauge drops and the ball in the flow meter slowly fall to the bottom of the scale, it indicates a small leak in the system.

Massive Leak: When the value of the pressure gauge reaches zero and the flow meter ball never falls to the bottom of the scale, it indicates a large leak in the system.
