Rosemount™ 3418 Eight-Path Gas Ultrasonic Flow Meter

The new Rosemount 3418 8-path ultrasonic flow meter crafted, developed, and designed by Emerson, offers the highest accuracy and best in class performance coupled with the same high functionality required by sophisticated fiscal measurement users. The 3418 combines the power of two interlocked 4-path British Gas design meters in one flow meter body. The second set of chords is the mirror image of the first, which allows the meter to cancel out the effects of swirl and cross flow. The 3418 Flow Meter boasts a 0.5 OIML accuracy class and requires only five diameters of straight run and no flow conditioner. Line Size: DN250 to DN1050 (10-in to 42-in) with British Gas (BG) orientation Fluid Type: Gas Accuracy: ±0.1% of reading relative over entire flow calibration range Repeatability: ±0.05% of reading for 5 to 100 ft/s (1.5 to 30.5 m/s) Velocity: Rated up to 100 ft/s (30 m/s) with over-range performance exceeding 125 ft/s (38 m/s) on some sizes Operating Temperature Range (Transducers): T-200: –50°C to 125°C (–58°F to +257°F)T-21: -20°C to +100°C (-4°F to +212°F)T-41: -50°C to +100°C (-58°F to +212°F)T-22: -50°C to +100°C (-58°F to +212°F) Operating Pressure Range (Transducers): T-200: 103 to 25,855 kPag (15 to 3,750 psig)T-21/T-41/T-22: 689 to 27,579 kPag (100 to 4,000 psig)T-21/T-41/T-22: 345 kPag (50 psig) available with reduced QmaxT-22: 0 to 25,855 kPag (0 to 3,750 psig) Materials: Carbon steel and stainless steel
