Overview

The OPTIFLUX 4050 is an electromagnetic flowmeter (EMF) for chemical applications in non-hazardous areas. It provides cost-effective measurements with good accuracy and standard diagnostics and communication options. The extra isolation of the electronic device and housing makes this EMF particularly suitable for use in areas with extreme humidity and chances of flooding.
