With a precision thermal mass flow sensor, no-moving parts construction, and space-saving design, the ST75V Hydrogen Flowmeter from Fluid Components International provides accurate and repeatable gas flow measurement in hazardous small line gas process applications where agency safety approvals are required. The meter provides built-in precision Vortab flow conditioning to deliver +1% of reading accuracy (+0.5% full scale) in line sizes from 0.25 to 2.0 in. (6 to 51 mm). ST75V features repeatability of +0.5% to ensure consistent hydrogen gas measurement. The Vortab flow conditioning technology reduces straight pipe run requirements by up to 70%, eliminating swirl and other pipeline flow distortions, according to the company. The meter has system safety approvals from FM/CSA Class 1, Div 1, Groups B, C and D; as well as Class 1, Div 2, Groups A, B, C and D, T4. It also meets requirements for ATEX II 3G EEx nA II T6; II 3D T65 C (dc powered version). www.fluidcomponents.com Fluid Components International
