The Smith Meter MPU 200 Series B is a single-path ultrasonic gas flowmeter for backup and check metering and for applications where reliability matters most. Its laterally offset straight path minimizes Reynolds-number effects and sits above the pipe centerline with a self-draining transducer port, making it well suited to wet gas and contaminated service where reflective designs struggle. It shares the MPU family's titanium flush-mount transducers, retraction under pressure and WinScreen diagnostics. For the newer MPU 200c, see the separate listing.

How to read the model code
Example: MPU-2-U-12-2-S-0-0-0-0-0. Read the code left to right; each position selects one option:
Model: 12 = MPU 1200 (6-path); 8 = MPU 800; 6 = MPU 600; 2 = MPU 200
Certification: U = US model, explosion-proof (UL/cUL); A = European model, ATEX
Diameter: Nominal size in inches (06 = 6", 12 = 12", etc.)
Flanges: 1 = 150; 2 = 300; 3 = 400; 4 = 600; 5 = 900; 6 = 1500; 7 = 2500
Transducer: S = standard; R = retractable under pressure
Optional interfaces: 0 = not required; F = fiber optic Ethernet (100Base-FL)
Local display: 0 = not required; D = with local display
Analog input: 0 = none; 1 = one 4-20 mA; 2 = two 4-20 mA; 3 = one 1-5 VDC; 4 = two 1-5 VDC (max 2 analog I/O total)
Analog output: 0 = none; 1 = one 4-20 mA; 2 = two 4-20 mA; 3 = one 1-5 VDC; 4 = two 1-5 VDC
Additional communication board: 0 = not required; C = with additional board
