Krohne offers SIL 2 for DK glass devices
Krohne’s variable area (VA) flowmeters DK46/47/48/800 with glass tube are now compliant with SIL 2 and are the first, and currently the only, SIL 2 glass tube purgemeters on the market.
Typical applications for the SIL 2 glass tube flowmeters are sample flow monitoring for process analyser systems, gas or liquid supply monitoring for mechanical sealing systems, purging monitoring for measuring systems (e.g. dP flow measurement), or nitrogen inertisation.
The SIL option is applicable for devices with stainless steel or brass process connections with bistable NAMUR limit switches and a junction box. It can be combined with ATEX certifications and also applies to VA flow controllers with individual probability of failures.
