Glass tube Variable Area Flowmeters with SIL Approval

In addition to the proven metal-cone variable area flowmeters, such as the H250 M40, the glass tube meters are now also available with SIL 2 approval for safety-related applications. 

Thus, a complete portfolio is also available of meters for extremely low flow rates of liquids (from ≥0.04 l/h or ≥0.1 GPH) and gases (from ≥5 Nl/h or 0.22 SCFH).

Like all other variable area flowmeters, these are so-called TYPE A devices, which means that all devices in redundant design can even be used in SIL 3 applications.

With this expansion, KROHNE has by far the widest product portfolio of SIL certified variable area flowmeters on the market and can serve practically all applications.
