Curve capture
Imported sensors store flow and pressure per serial.
Applications
Where the water actually moves.
Household RO
50–800G under-sink and tankless. Self-priming when the tank sits high.
Commercial & boilers
800–1600G, brushless duty, office and restaurant recovery.
Tea / coffee / micro
38M and 801/802/901 loops that sit beside the RO core.
Send the membrane. We’ll send the curve.
1-hour first response. Custom flow and noise matching. Samples from Jiangmen, engineering from Shunde.
