The Smith Meter AccuPlus is a positive displacement additive injector that meters additives accurately into mainstream products such as gasoline, diesel and heating oil. One meter can handle a single additive or up to eight through a common manifold. A high-resolution encoder gives precise injections at low PPM rates, and the low-pressure-drop, modular design with calibration ports keeps installation and service simple. Typical uses are fuel performance additives, markers and dyes, cold flow improvers and liquid fertilizers.

How to read the model code
Example: LEA-C-1-C-1-A-N-0-0. Read the code left to right:
- Block type: LEA = AccuPlus
- Meter piston material: C = carbon
- Number of additive valves: 1-8 (2 and up include manifolds: 2 = 1 manifold, 3-4 = 2, 5-6 = 3, 7-8 = 4)
- Valve type: C = Coax
- Power: 1 = 120 VAC / 60 Hz; 2 = 230 VAC / 50 Hz
- Approval: A = ATEX / IECEx
- Mounting: N = none; U = U-bar; X = other (consult factory)
- Proportional valve: 0 = none; 1 = proportional valve (needs at least 1 manifold)
- Number of manifolds for multiple inlet valves: 0 = none (max 1 inlet valve); 1-4 manifolds (max 2, 4, 6 or 8 inlet valves); spare ports blind-covered
