The Smith Meter Ultra 8c is an eight-path liquid ultrasonic flowmeter for custody transfer of refined products, LPG and light to heavy crude oils. Crossing measurement paths cancel swirl, so it installs with only 5D of upstream straight run and no flow conditioner, and dynamic profile compensation keeps it linear from laminar to turbulent flow. Flush, non-intrusive transducers sit in removable wells for replacement under pressure, with an optional low-frequency transducer for the heaviest and dirtiest fluids.

How to read the model code
Example: 8-S-06-1-1-S-S-B-C-40 with UMC-E-A-P-N-S-0-B-0. Read the code left to right; each position selects one option:
Position 1 (Code): 8 = Ultra 8c
Position 2 (Certification): S = standard UL/cUL, ATEX, IECEx; B = INMETRO UL Brazil
Positions 3-4 (Diameter): 06, 08, 10, 12, 14, 16, 18, 20, 24, 26, 30 inch (other sizes or custom ID, consult factory)
Position 5 (End connections): 1-4 = Class 150/300/600/900 ASME flange; 5-8 = Class 150/300/600/900 RTJ
Position 6 (Body material): 1 = carbon steel; 2 = 300 series stainless; X = special
Position 7 (Transducer): S = standard titanium; X = special (non-Buna-N service)
Position 8 (Transducer type): S = standard; L = low frequency (high viscosity); H = high frequency
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 ID)
Electronics (UMC code): UMC-(E explosion-proof / B INMETRO)-(A aluminum / S stainless)-(P pedestal / H with height extension)-(M M20 / N 1/2" NPT)-S-0-(B blind / T 5.7" touchscreen)-(0 none / 1 HART)
Remote display (optional): TCI-(E/B)-(A/S)-S-(M/N)-(S/X); see the Ultra Series Remote Touchscreen Display listing
