The OPTIFLUX 7300 is a an electromagnetic flowmeter (EMF) for measuring very low conductivity liquids (≥0.05 μS/cm). The high-end meter is particularly suitable for applications with extremely adhesive and greasy media that tend to form an insulating film. It is also the first choice for applications involving high vibration and noise as well as oxidizing, abrasive or toxic chemicals. The leak-tight, vacuum and temperature resistant ceramic tube construction also complies with regulations of the food industry (FDA, EC1934/2004). Therefore, hygienic flow measurement with advanced requirements is another field of application.

The electrodes of the OPTIFLUX 7300 are designed as large-area capacitor plates, mounted behind the ceramic measuring tube. Unlike conventional EMFs, its electrodes have no direct contact with the process liquid. The non-contacting capacitive signal pickup between medium and electrodes enables reliable measurement even in the event of non-conductive product build-up on the tube wall. The flowmeter comes with flange or as flangeless and space-saving wafer version. It features advanced diagnostics and multiple digital communication options. A full on-site verification of the OPTIFLUX 7300 without process interruption can be carried out using the OPTICHECK service tool.
