OPTIFLUX 4300 for Sewage Treatment

The OPTIFLUX 4300 is an electromagnetic flow meter (EMF), or magmeter, for advanced water processing applications with aggressive liquids or abrasive media. The high-end flow meter is particularly suitable for critical applications requiring high accuracy and many diagnostic functions such as sewage treatment or handling sludge. It enables reliable measurement even under very harsh process conditions with temperatures up to 356˚F, low conductivities (≥1 µS/cm), high solid contents (up to 70%), and high pressures (up to 1500 bar / 21751 psi). For custody transfer applications, the OPTIFLUX 4300, from KROHNE, has a wide range of certifications including OIML R49 and R117 or MI-001 and MI-005. It is also ideal for flow measurement in district heating networks requiring MI-004 approval.

• 3 x 4-20 mA, HART, Modbus, FOUNDATION Fieldbus, Profibus-PA/DP, PROFINET
• for custody transfer: OIML R49, OIML R-117; MI-001, MI-004, MI-005
• standard measurement accuracy: ±0.2% or ±1mm/s of measured value (MV)
• for hazardous areas: ATEX, IECEx, NEPSI, FM, CSA, EAC, INMETRO
• special designs, sizes, inner diameters and liner thicknesses on request

Features of the OPTIFLUX 4300 for Sewage Treatment*

The OPTIFLUX 4300 is available in a wide diameter range up to DN3000 / 120″. Its virtual reference option allows for a very cost-saving measuring mode without additional grounding rings – particularly when it comes to large diameters. Installation in measurement chambers subject to (constant) flooding is possible with the IP68 / NEMA 6P rated version. The meter is approved for use in hazardous areas and offers various digital communication options. A full on-site verification of the OPTIFLUX 4300 without process interruption can also be carried out using the OPTICHECK service tool.

• bi-directional flow measurement over a wide dynamic range; for example, turn down ratio: 1000:1
• available with virtual reference grounding method, which means grounding rings are not necessary
• extensive flowmeter and process diagnostics (including NE 107)
• PTFE, PFA, ETFE, hard rubber, soft rubber, PU liner, which offer excellent chemical and abrasion resistance
• wide range of electrode materials
• optional external coatings for offshore or subsoil installation (also according to ISO 12944)
• full bore design: no moving parts, no wear, in addition to no pressure loss
• on-site verification of flow meter with OPTICHECK service tool
