The Smith Meter Ultra 6 is a six-path transit-time ultrasonic flowmeter for custody transfer, allocation, line balancing and leak detection on refined products and crude oil. Flush-mounted titanium transducers leave the bore unobstructed, so pressure drop equals that of straight pipe and there are no moving parts to wear. The six-path layout and strong noise immunity hold accuracy on high-viscosity crude with changing flow profiles, and transducers can be replaced in-line without shutting down.

How to read the model code
Example: 6U0611S011CS. Read the code left to right; each position selects one option:
Position 1 (Model): 6 = Ultra 6
Position 2 (Certification): U = US model, explosion-proof (UL/CSA); A = European model, ATEX/IECEx
Positions 3-4 (Diameter): 06, 08, 10, 12, 14, 16, 18, 20 (inches)
Position 5 (End connections): 1 = Cl 150 RF; 2 = Cl 300 RF; 3 = Cl 600 RF; 4 = Cl 900 RF; 5-8 = Cl 150/300/600/900 RTJ
Position 6 (Materials): 1 = carbon steel; 2 = 300-series stainless; X = special
Position 7 (Transducer): S = standard titanium; X = special
Position 8 (Optional interface): 0 = not required
Position 9 (Analog inputs (max 2 analog I/O total)): 0 = none; 1 = one 4-20 mA; 2 = two 4-20 mA; 3 = one 1-5 VDC; 4 = two 1-5 VDC; 5 = one RTD; 6 = one 4-20 mA + one RTD; 7 = one 1-5 VDC + one RTD
Position 10 (Analog outputs): 0 = none; 1 = one 4-20 mA; 2 = two 4-20 mA; 3 = one 1-5 VDC; 4 = two 1-5 VDC
Position 11 (Mechanical certification): B = ASME B31.3; P = PED; C = CRN; X = special
Position 12 (Software): S = standard; X = special
