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. It
reports battery charge condition and even provides a cable-break alarm.
