1 SAFETY INSTRUCTIONS OPTIFLUX 2070 1.1 Intended use The electromagnetic flowmeter OPTIFLUX 2070 has been designed for measuring potable water and water with suspended particles. The OPTIFLUX 2070 features not only accurate flow measurement, but also continuous diagnostics in accordance with applicable standards. This self-diagnosis monitors and automatically reports improper functioning of the electronics, or faulty sensor electrodes.
SAFETY INSTRUCTIONS 1 OPTIFLUX 2070 1.2.3 Display conventions The following symbols are used to help you navigate this documentation more easily: WARNING! These warning signs must be observed without fail. Even only partial disregarding such warnings can result in serious health damage, damage to the device itself or to parts of the operator ’s plant. DANGER! This symbol designates safety advice on handling electricity. CAUTION! These warnings must be observed without fail.
