The Smith Meter MPU 600c is a cost-effective three-path ultrasonic gas flowmeter built on the Series C electronics platform. Transit-time measurement with no moving parts gives stable, low-maintenance service, while digital filtering improves noise immunity. Transducers can be retracted under pressure, 14 days of process data are stored on board for diagnostics, and the meter can be run from a web browser or an optional explosion-proof color touch screen.

How to read the model code
Example: MPU6-S-06-1-1-S-S-B-C with UMC-E-A-P-N-S-0-B-0. Read the code left to right; each position selects one option:
Position 1 (Code): MPU6 = MPU 600c
Position 2 (Certification): S = standard: UL/cUL, ATEX, IECEx
Positions 3-4 (Diameter): Nominal size in inches (06, 08, 10, 12, etc.)
Position 5 (End connections): 1 = Class 150; 2 = 300; 3 = 400; 4 = 600; 5 = 900; 6 = 1500; 7 = 2500 ASME flange
Position 6 (Body material): 1 = carbon steel (A350 LF2); 2 = 300 series stainless (A182 F316); X = special
Position 7 (Transducer): S = standard titanium; X = retractable under pressure
Position 8 (Transducer type): S = standard; L = special (non-Buna-N service)
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
Electronics (UMC code): UMC-E-(A aluminum / S stainless)-(P pedestal / H pedestal with height extension / E pedestal with Exe box / C custom)-(M M20 / N 1/2" NPT)-S-0-(B blind cover / T 5.7" touch screen)-(0 none / 1 HART)
