CAUTION!
All display and monitoring devices in a system that
is used for conveying explosive material must
comply with the Directive 2014/34/EC (ATEX) with
respect to equipment category, temperature class

The process water supply in the reservoir must also be monitored.
We also recommend the installation of a speed counter.
