Chemically resistant liner materials
With extra isolation of electronics for use in high humidity areas
Flange: DN2.5…1200 / ⅒…48", max. PN40 / ASME Cl 600
4…20 mA, pulse, frequency, status, HART®, Modbus
The OPTIFLUX 4050 is an electromagnetic flowmeter (EMF) for chemical applications in non-hazardous areas. It provides cost-effective measurements with good accuracy and standard diagnostics and communication options. The extra isolation of the electronic device and housing makes this EMF particularly suitable for use in areas with extreme humidity and chances of flooding.
The OPTIFLUX 4050 features a selection of chemically resistant liners and electrodes. Due to its full bore design without moving or intruding parts, there is no pressure loss and no maintenance required. The EMF comes with current output (incl. HART®) or active pulse/frequency output and Modbus. A full on-site verification of the EMF without process interruption can be carried out using the OPTICHECK service tool.
· Bi-directional flow measurement over a wide dynamic range (turn down ratio: 1000:1)
· Tropicalized electronics for use in areas with extreme humidity and chances of flooding
· Excellent price/performance ratio
· PTFE, PFA, ETFE, hard rubber, soft rubber or PU liner: excellent chemical and abrasion resistance
· Signal converter with display or as blind version
· Full bore design: No moving parts, no wear, no pressure loss
· On-site verification of flowmeter with OPTICHECK service tool
