Electromagnetic flowmeter for safety instrumented systems (SIS) and high-accuracy requirements
- Certified for safety applications up to SIL 2/3, with automated partial proof test capability for extended proof test intervals
- Best-in-class diagnostic test interval incl. fault response time of only 2 minutes
- SIL 2/3 up to DN600 / 24″; non-SIL up to DN2000 / 80″ (larger on request)
- Pulse, frequency, status, 4…20 mA, HART®7
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.
