Electromagnetic Flow meter OPTIFLUX 2100

The OPTIFLUX 2100 is an electromagnetic flowmeter (EMF) for standard water and wastewater applications. It is the ideal solution for all general flow applications where reliable flow measurement with sufficient yet not extremely high accuracy is required. Installation in measurement chambers subject to (constant) flooding is possible with the remote IP68 / NEMA 6P rated version.

Its wear resistant liner materials as well as its full bore design without moving parts make the OPTIFLUX 2100 an effective replacement of mechanical water meters in drinking water distribution networks. The meter features a wide range of approvals necessary for potable water measurement. A full on-site verification of the meter without process interruption can be carried out using the OPTICHECK service tool.
