The Smith Meter Guardsman L Series are rimless-rotor turbine meters built for truck and rail loading racks, where they provide custody-transfer accuracy on refined petroleum products. Three models cover 1 to 4 inch lines: the LB (ball bearing, 1-1.5 in), the LJ (tungsten carbide journal bearing, 1.5-2 in) and the LSJ (journal bearing with an integral strate-plate flow conditioner, 3-4 in). Horizontal and vertical (upward flow) versions are offered, and the meters work with AccuLoad turbine meter diagnostics.

How to read the model code
Example: K2GDA001C00. Read the code left to right; each position selects one option:
- Position 1 (Code): K = catalog code
- Position 2 (Product line): 2 = turbine meter
- Positions 3-4 (Model and size): LB: C1 = 1 in, CA = 1.5 in; LJ-H: EA = 1.5 in, EB = 2 in; LJ-V: PB = 2 in; LSJ-H: GD = 3 in, GE = 4 in; LSJ-V: SD = 3 in, SE = 4 in
- Position 5 (Pressure class): A = Class 150; B = Class 300
- Position 6 (End connections): 0 = carbon steel RF flanges
- Position 7 (Internal configuration): 0 = unidirectional
- Position 8 (Pickups / electronics): 0 = 1 coil; 1 = 1 coil + preamp (standard); 2 = 2 coils; 3 = 2 coils + 2 preamps; 4 = 2 coils + 1 preamp; 7 = 3 coils + 2 preamps; P = 3 coils + 3 preamps; E = two PA-IS-1 (Ellerbek); 8/9 = MMRT-II versions; S/T = 1/2 coils + AccuLERT XU
- Position 9 (Testing / linearity): 0 = ±0.25% (1-2 in); C = ±0.15% tested with strate plate (3-4 in)
- Position 10 (Certification): 0 = UL/cUL; 3 = ATEX/IECEx; 4 = ATEX/IECEx/PED (Ellerbek); 5 = UL/cUL/CRN; 6 = UL Brazil/INMETRO
- Position 11 (Specials): 0 = none; X = special, specify
