The Smith Meter MPU 800c is a four-path ultrasonic gas flowmeter for custody transfer, built on the Series C electronics platform. It is verified to AGA 9 (2007), OIML R137, Welmec 7.2 and ISO 17089, and reaches ±0.1% with flow calibration even with 10D straight run and no flow conditioner. Retractable titanium transducers, 14 days of on-board diagnostic data, a web-browser interface and an optional explosion-proof color touch screen keep operation and service simple.

How to read the model code
Example: MPU8-S-12-2-1-X-S-B-C with UMC-E-A-P-N-S-0-T-0. Read the code left to right; each position selects one option:
Position 1 (Code): MPU8 = MPU 800c
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)
