With its precision thermal mass flow sensor, no-moving parts construction and space-saving design, the advanced ST75V Hydrogen Flow Meter from Fluid Components International provides highly accurate and repeatable gas flow measurement in hazardous small line gas process applications where agency safety approvals are required. FCI’s advanced ST75V Hydrogen Flow Meter combines highly reliable, no-moving parts thermal mass flow sensing technology with 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 inches (6 to 51mm). The ST75V is also exceptionally dependable featuring repeatability of +0.5% that will ensure consistent hydrogen gas measurement to meet rigorous process quality standards and reduced plant operating costs.
The ST75V Hydrogen Flow Meter’s built-in Vortab flow conditioning technology reduces straight pipe run requirements by up to 70 percent, eliminating swirl and other pipeline flow distortions to ensure precise gas flow measurement in challenging conditions. In many plants and skid-mounted applications, crowded equipment and piping configurations result in an inadequate or unavailable straight-on or an obstructed flow environment that often affects flow measurement accuracy. The ST75V Hydrogen Flow 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 the requirements for ATEX II 3G EEx nA II T6; II 3D T65 C (dc powered version).
