Variable area flowmeter

Krohne has extended the available options for the H250 M40 flowmeter to suit the requirements of oil and gas applications, such as flow measurement on injection skids for corrosion, scale and hydrate inhibitors like methanol or monoethylene glycol. Common areas of application are also measuring agents and solvents in gas treatment processes like sweetening and dehydration of natural gas as well as reliably monitoring small amounts of nitrogen and fuel gas.

Standard materials for the range of DN15…150 / ½…6″ flanged process meters include NACE MR0175/MR0103 compliant 316L or materials and welding following the NORSOK standard. Hastelloy, Monel, 6Mo, titanium and now also Inconel are available as optional materials to provide high corrosion resistance to any kind of fluid. Stainless steel indicator housings and offshore protective coatings are available.

Flange connections reach up to ASME B16.5 Class 2500 flanges. Higher pressure ratings can be realised when applying API flanges. For hazardous gas and dust areas, H250 M40 has achieved more than 30 approvals worldwide, including ATEX, IECEx, usFMc, NEPSI, INMETRO, KGS, EAC and PESO/CCOE. For quality assurance, comprehensive tests and certifications are in place such as positive material identification, material mill certificates, X-ray and dye-penetration examination of the welding seams, pressure and leakage tests, and finally, third-party factory inspection.
