5.4 Automatic Refill and Level Sensor
The automatic refill module allows the refill of the liquid pressure tank without having to shut down the spray
process. Auto
-
refill (optional) comes with a level sensor, pneumatic ball valve, and optional drum pump. The auto
refill module accepts a signal from the level sensor that sticks out of the top of the tank showing a gauge for the
liquid amount and triggers a drum pump to refill the tank.

the yellow light on the controller will illuminate indicating the automatic refill has been triggered and is currently
