The Smith Meter AccuLoad III Split Architecture system controls an entire loading lane from one installation: a Man Machine Interface (MMI) provides the display and keypad, while a separate Flow Control Module (FCM) houses the control boards and I/O. Up to 18 loading arms and 24 meters can be controlled, with six arms loading simultaneously from one MMI or twelve with dual MMIs (swing-arm operation). Each arm can run straight product, sequential, ratio, side-stream, hybrid or wild-stream blending. Both modules mount in Division 2 or general-purpose areas.

How to read the model code
Example: ALIII-MMI-ALXM-1-1-0 (MMI) + ALIII-FCM-SA8-3-10 (FCM) + SAA-ALX2-A00000-A (board set). Read the code left to right; each position selects one option:
- MMI: Hardware model / firmware: ALIII-MMI = Man Machine Interface; ALXM = MMI operation
- MMI: Stop button: 0 = none; 1 = 120/230 V
- MMI: Indicator lights: 0 = none; 1 = 120 V red/green; 2 = 240 V red/green; 3 = 120 V green/green
- MMI: Hardware option: 0 = none; 1 = card reader
- FCM: Number of loading arms: SA2, SA4, SA6, SA8, SA10, SA12, SA14, SA16, SA18 = 2 to 18 arms
- FCM: Number of board sets: 1-4 (each set = KDC, EAAI and BSE boards)
- FCM: Fuse holders: 0-50
- Board set (one per set): SAA / SAB / SAC / SAD = board set A-D; firmware ALX1-ALX6 = 1-6 arms; analog modules 5 digits (RTDs, 4-20 mA in, 4-20 mA out, 1-5 VDC in, 1-5 VDC out); hardware option blank = none, A = AICB board
- Remote AICB: REM-XP-A (one AICB) or REM-XP-AA (two AICBs), explosion-proof housing
A complete model number for the MMI, the FCM and each board set is required when ordering.
