KROHNE OPTIFLUX 4300 electromagnetic flowmeter, DN2.5–3000, ±0.2%, custody transfer

The KROHNE OPTIFLUX 4300 is an electromagnetic flowmeter for demanding process measurement and custody transfer of electrically conductive liquids. The full-bore design without moving parts causes no pressure loss and does not wear. Virtual reference eliminates the need for grounding rings.

Accuracy ±0.2% or ±1 mm/s of measured value, bidirectional measurement, turndown 1000:1. Flanges DN2.5…3000 up to PN40 / ASME Class 600, liners PTFE, PFA, ETFE, hard and soft rubber, polyurethane. Explosion protection ATEX, IECEx, NEPSI, FM, CSA, EAC, INMETRO; NE 107 diagnostics.
