Terms & Conditions
Overview The OPTIFLUX 4400 electromagnetic flowmeter (EMF) is developed in accordance with IEC 61508 for safety-related applications up to safety integrity level (SIL) 2/3. It features automated partial proof testing capabilities, which allows to extend the time interval between full proof tests and increase plant uptime in safety instrumented systems (SIS).
Next to safety applications, the OPTIFLUX 4400 is particularly suitable for process applications with high accuracy requirements and difficult flow conditions such as pulsating and turbulent flow. Due to its wide selection of lining and electrode materials it can well be used for flow measurement and dosing of chemicals and corrosive liquids such as acids. Utilizing the EMF's improved conductivity measurement, operators can also monitor a defined range of conductivity.
The OPTIFLUX 4400 comes with a wide range of flowmeter and process diagnostics for a high degree of reliability. Among others, it features a best-in class diagnostic test interval incl. fault response time of only 2 minutes. If running out of spec, the flowmeter is able to issue an alarm to the control room much faster than other EMFs available on the market. A full on-site verification of the OPTIFLUX 4400 without process interruption can be carried out using the OPTICHECK service tool.
Features & Options
- Automated partial proof testing capability for extended full proof test intervals
- Integrated conductivity measurement
- Enhanced diagnostic package:
- Compliant with NAMUR NE 107
- Diagnostic test interval incl. fault response time of only 2 minutes: alert issued if meter runs out of spec
- Detects gas bubbles, solids, electrode corrosion and deposits on the electrodes, conductivity changes, an empty or partially filled pipe, a disturbed flow profile, external magnetic fields, etc.
- Redundant data storage
