OPTIFLUX 4400 Magmeter

The OPTIFLUX 4400 electromagnetic flow meter (EMF), or magmeter, arrives in accordance with IEC 61508 for safety-related water and wastewater applications, up to safety integrity level (SIL) 2/3. It features automated partial proof testing capabilities, which allows extension in the time interval between full proof tests while increasing plant uptime in safety instrumented systems (SIS).

Aside from safety applications, the OPTIFLUX 4400 is particularly suitable for process applications with high accuracy requirements and difficult flow conditions, for example, pulsating and turbulent flow. Due to its wide selection of lining and electrode materials, it’s ideal for flow measurement and dosing of chemicals and corrosive liquids such as acids. This magmeter can improve conductivity measurement, and operators can also monitor a defined range of conductivity.

The OPTIFLUX 4400 magmeter comes with a wide range of flow and process diagnostics for a high degree of reliability. In addition, it features a best-in-class diagnostic test interval including a fault response time of only two minutes. If running out of spec, this flow meter will issue an alarm to the control room much faster than other EMFs on the market. The OPTICHECK service tool can also provide a full on-site verification of the OPTIFLUX 4400 without process interruption.

Features of the OPTIFLUX 4400 Magmeter*

• automated partial proof testing capability for extending full proof test intervals
• integrated conductivity measurement
• enhanced diagnostic package:
  • compliant with NAMUR NE 107
  • diagnostic test interval including fault response time of only 2 minutes, it also alerts if meter runs out of spec
  • detects gas bubbles, solids, electrode corrosion, deposits on the electrodes, conductivity changes, an empty or partially filled pipe, a flow profile disturbance, external magnetic fields, etc.
  • redundant data storage
  • real-time clock for logging events
  • user-friendly color display for status indication
• ease of installation and device set-up:
  • optimized device menu with reduced menu items for quick commissioning
  • available with “virtual reference” option: cost-saving installation without grounding rings (in non-SIL applications)
• high measuring accuracy and long-term stability, for example, measuring error of only ±0.2% of measured value ±1 mm/s
• wide range of liner and electrode materials
• approval for use in hazardous areas: ATEX, IECEx db eb
• field device verification of flowmeter with the OPTICHECK Master and OPTICHECK DTM service tools, e.g. for partial proof test documentation according to IEC 61508
