The Smith Meter Model K12 is a 12-inch, steel, double-case, straight-through rotary vane positive displacement (PD) meter in the Crude Transportation (CT) Series of large PD meters. CT Series meters use lightened blades, full-width wear strips and tungsten carbide roller pins for long service in harsh crude oil, and are equally suited to refined products for custody transfer, batching, blending and leak detection.

How to read the model code
Example: KK12S3BBS00. Read the code left to right; each position selects one option:
Position 1 (Catalog code): K = catalog code
Positions 2-3 (Model / size): K12 = 12 in
Position 4 (Flow path): S = straight-through
Position 5 (Pressure class, RF flanges): 3 = Class 150 (285 psi); 6 = Class 300 (740 psi); 7 = Class 600 (1,480 psi); 8 = Class 900 (2,220 psi) per catalog guide
Position 6 (Meter gearing): G = gallons; B = barrels; D = dekaliters; I = imperial gallons; P = pounds (consult factory for I and P)
Position 7 (Seals): B = Buna-N; V = FKM; T = PTFE; L = low-temperature FKM
Position 8 (Trim): S = standard; A = all iron; L = LPG
Position 9 (Temperature compensation): 0 = none; A = ATC (factory-set); B = ATG (field-adjustable)
Position 10 (Special requirements): 0 = standard; P = EU PED (Ellerbek-built); C = CRN + low-temp material; L = low-temp material
