1.2 Options The reliable solution for the water and wastewater industry From standard to customized For easy ordering the standard range of the OPTIFLUX 2000 covers all popular sizes, flange materials and connections (ASME, EN, JIS, AWWA). But KROHNE does not stop here. Our extensive engineering department is dedicated to provide solutions for all specifications not covered by our standard range. Requests for special sizes, flange connections, pressure ratings, building lengths, and materials, will always get a serious review. Whenever possible we will engineer a flow meter that fits your application....

Custody transfer In combination with the IFC 300 signal converter the OPTIFLUX 2000 is suitable for custody transfer applications. It meets the requirements of OIML R49 and can be verified according to Annex MI-001 of the Measuring Instruments Directive (MID) / UK Regulation 2016. All water meters for legal metrology purposes in Europe require certification under the MID. The EC type examination certificate for the OPTIFLUX 2300 is valid for the compact and the remote version and applies for forward and reverse flow.

1.3 Measuring principle An electrically conductive fluid flows inside an electrically insulated pipe through a magnetic field. This magnetic field is generated by a current, flowing through a pair of field coils. Inside of the fluid, a voltage U is generated: U=v*k*B*D in which: v = mean flow velocity k = factor correcting for geometry B = magnetic field strength D = inner diameter of flowmeter The signal voltage U is picked off by electrodes and is proportional to the mean flow velocity v and thus the flow rate Q. A signal converter is used to amplify the signal voltage, filter it and convert...
