The Prowirl D sensor can be installed directly between flanges and thus serves as the functional device for applications in ancillary processes at little installation cost. With genuine loop-powered technology, Prowirl D 200 enables cost-effective and seamless integration into existing infrastructures. It offers highest operational safety in hazardous areas. Heartbeat Technology enables process safety at all times.
Preferred measuring principle for wet/saturated/superheated steam, gases & liquids (also cryogenic)
For all basic applications and for 1-to-1 replacement of orifice plates.
