The Smith Meter MPU 800 Series B is a four-path (8-transducer) ultrasonic gas flowmeter with non-intrusive, flush-mounted titanium transducers, offering custody-transfer performance under most conditions at a lower cost than the six-path MPU 1200. It is AGA 9 verified by independent labs, tolerates high ultrasonic noise thanks to digital signal processing, and allows transducer removal under pressure without shutdown or recalibration. Sound velocity, density checks and full diagnostics are available through WinScreen software.

How to read the model code
Example: MPU-8-U-08-2-S-0-0-1-0-0. 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
