The Smith Meter Ultra 6c is the current-generation six-path liquid ultrasonic flowmeter for custody transfer of light, medium and heavy petroleum liquids at terminals, on pipelines and offshore (FPSO and platforms). Its six-path layout measures and corrects for crossflow and swirl, and an optional low-frequency transducer keeps signal strength on high-viscosity or contaminated crude and during cold starts. It is paired with the UMC meter-mounted electronics, which can carry a 5.7-inch color touch screen, and every meter is flow-tested on hydrocarbon at the factory.

How to read the model code
Example: 6S0611SSBC-40. Read the code left to right; each position selects one option:
Position 1 (Model): 6 = Ultra 6c
Position 2 (Hazardous-location certification): S = UL/cUL, ATEX, IECEx
Positions 3-4 (Diameter): 06, 08, 10, 12, 14, 16, 18, 20, 24, 25, 30 (inches)
Position 5 (End connections): 1-4 = Class 150/300/600/900 RF; 5-8 = Class 150/300/600/900 RTJ
Position 6 (Body material): 1 = carbon steel; 2 = 300-series stainless; X = special
Position 7 (Transducer material): S = standard titanium; X = special
Position 8 (Transducer type): S = standard; L = low frequency (high viscosity)
Position 9 (Mechanical certification): B = ASME B31.3; P = PED; C = CRN; X = special
Position 10 (Ethernet): C = 2 twisted pair; F = 1 twisted pair + 1 optical
Positions 11-12 (Inlet ID (meter run schedule)): 10, 20, 30, 40, 60, 80, ST (STD), XS, CD (custom)
Electronics (UMC enclosure code): UMC-E-(A aluminum / S stainless)-(P pedestal / H high-temp extension / E Ex e box)-(M M20 / N 1/2 in NPT)-S-0-(B blind / T touch screen)-(0 none / 1 HART)
