Space-saving Hydrogen flowmeter is
approved
The new space-saving ST75V Hydrogen flowmeter with agency approvals for hazardous areas is ideal for oil/gas refineries, ammonia production, food plants, mining, and fuel cell skids
With its precision thermal mass flow sensor, no-moving part construction and space-saving design, the advanced ST75V Hydrogen flowmeter 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 The FCI advanced ST75V Hydrogen flowmeter 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)

Two-wire level monitoring and interface control
The rugged NuTec LS2000 Level Switch provides highly reliable level monitoring and interface control in demanding process industries, giving low maintenance, long-life and low cost-of-ownership
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 flowmeter uses built-in Vortab flow conditioning technology, that reduces straight pipe run requirements by up to 70%, 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.

Flow and liquid level interface switch is SIL2
Built to comply with process industry precision requirements for flow, level and interface sensing in liquid, gas or foam, the innovative FLT93 Switch Series is now rated SIL2 compliant
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).
The ST75V Hydrogen flowmeter is ideal for a wide range of small line process applications.
In the petroleum and chemical industries, hydrogen is utilised in many fuel and other chemical upgrading processes.
In fuel cell systems, particularly skid-mounted applications where real estate and piping straight-run is limited, the ST75V compact size is a big advantage.
The production of ammonia is also dependent on hydrogen for the fertiliser industry.
Hydrogen has been used as well as a hydrogenating agent in the food industry and a reducing agent for metallic ores.
Blending high accuracy with extensive features, the ST75V Hydrogen flowmeter measures gas flows from 0.01 SCFM (0.01 NCMH) to 559 SCFM (950 NCMH).
Standard outputs for the ST75V are fully scaleable 4-20mA and 0-10V that are user assignable to flow rate and/or temperature and a 0-1kHz pulse output of total flow.
The instrument can be ordered for powering by 24VDC or 115/230VAC, with or without a built-in LCD digital display, and in local or remote-mounted electronics configurations.
The thermal mass flow sensor designed for the ST75V Hydrogen flowmeter is all-welded stainless steel with Hastelloy-C tips that provide extra protection against corrosive conditions within the pipe.
With its unique flow sensor design, there are no orifices or moving parts to clog or foul, which eliminates unplanned shutdowns, reduces maintenance and extends sensor life.
The transmitter is enclosed in a rugged, all-metal, dust and water resistant, NEMA Type 4X (IP67) rated package which is FM and ATEX agency approved for installations in hazardous locations.
