- Clear completion signalA built-in flow indicator tells the operator when filling is complete.
A better watering routine
in four simple steps
The Flow-Rite system lets an operator service every cell from one connection while reducing exposure to acid and inconsistent fill levels.
Connect
Attach the water supply to the system's quick coupling.
Fill
Water flows through acid-resistant tubing to every cell.
Stop
Automatic valves shut off at the correct electrolyte level.
Disconnect
Confirm flow completion and return equipment to service.
