KROHNE has introduced new options for low-flow measurement with variable area flowmeters
The H250 M40 with its extensive range of features and options is now available for very low flow rates, and the purgemeters DK32, DK34 and DK37/M8M have been re-assessed as SIL2 compliant.
The new H250 M40 low flow option combines the small measuring cones of the purgemeter DK37 with the wide range of process connections, communication options and H250 M40 ex-approvals. The new option is suitable for fluid flows starting at 0.16 l / h/0.04 GPH and gas flows starting at 1.6 l / h/0.06 SCFH.
Formerly rated SIL1, the purgemeters DK32, DK34 and DK37/M8M have been re-assessed as SIL2 compliant according to IEC 61508-2:2010 for the versions with NAMUR safety switches as well as for the 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 in the download centre on the KROHNE website.
