KROHNE, Inc.’s H250 M40 variable-area flowmeter, now available with extensive options for low-flow measurement. The flowmeter’s existing DK32, DK34 and DK37/M8M purge meters are now rated as SIL2-compliant. The H250 M40 low-flow option features an extensive range of process connections, communication options and ex-approvals and now offers the DK37 purge meter’s small measuring cones, suitable for liquid flows starting at 0.16 L/h (0.04 gph) and gas flows starting at 1.6 L/h (0.06 standard cu.ft. per hour [SCFH]). Formerly rated Safety Integrity Level (SIL) 1, the DK32, DK34 and DK37/M8M purge meters have been re-assessed as SIL2-compliant according to IEC 61508-2:2010 for both NAMUR safety switches and NAMUR standard switches. Optional mechanical flow controllers or flange adapters are included in the SIL compliance. The SIL declarations of conformity and SIL safety manuals are available at the download center on the website.
