The Smith Meter AccuLoad III is a multi-microprocessor electronic preset delivery system for truck, rail and marine loading. The ALIII-S handles up to two arms and three product meters; the ALIII-Q handles up to six arms and six product meters. Each arm can run straight product, sequential, ratio or side-stream blending, with up to 50 recipes, 24 additive meters, temperature/pressure compensation and density correction, card reader support and Ethernet. AccuLoad III has been succeeded by AccuLoad IV (an upgrade kit is available), and FMS continues to supply and service existing AccuLoad III installations.

How to read the model code
Example: ALIII-Q-XP-ALX1-A00000-0. Read the code left to right; each position selects one option:
- Position 1 (Product): ALIII = AccuLoad III
- Position 2 (Hardware model): S = ALIII-S; Q = ALIII-Q
- Position 3 (Housing): XP = explosion-proof (UL/cUL, EEx d IIB, IP65)
- Position 4 (Firmware / arms): ALX1-ALX6 = 1-6 arm operation (3-6 arms Q only); ALP1-ALP6 = PEMEX non-resettable volume versions
- Position 5 (Analog modules (5 digits, max 6)): Digit 1 = RTDs; 2 = 4-20 mA inputs; 3 = 4-20 mA outputs; 4 = 1-5 VDC inputs; 5 = 1-5 VDC outputs
- Position 6 (Hardware option): 0 = none; A = AICB board; AA = two AICBs (Q only); M = ComFlash mass storage; AM = AICB + ComFlash; AAM = two AICBs + ComFlash (Q only)
- Remote AICB (REM code): REM-XP-(A one AICB / AA two AICBs)
A complete model number is required when ordering. For new installations, ask FMS about AccuLoad IV or the AccuLoad III to IV upgrade kit.
