SITRANS FMT020 – Next generation MAG transmitter

High-performance and intelligent flow measurement for demanding process applications

SITRANS FMT020 is a robust and intelligent transmitter designed to provide accurate and reliable flow measurement of conductive liquids in a variety of industrial processes. It is the successor to the proven MAG 5000 and MAG 6000 transmitters, combining their unique features with advanced new functions.

Advanced technology and flexible installation options
FMT020 retains the flexible installation design from its predecessors, allowing it to be mounted both compactly and remotely in the same enclosure. The modular design enables easy replacement of the transmitter, addition of communication modules, and use of the Sensorprom memory device for quick commissioning, immediate measurement, and secure data storage.

In addition to these features, the FMT020 can simultaneously measure volume flow, flow velocity, and electrical conductivity. It also offers enhanced diagnostics with empty pipe monitoring and self-testing of the unit, as well as multifunctional input and output channels for process control. User-friendliness is a key focus with a unified operating structure.

Features and Benefits

• Simultaneously measures volume flow, flow velocity, and electrical conductivity
• Cost-effective solution, backward compatible with older flow meter sensors (MAG 5100W, MAG 3100, MAG 3100 P, MAG 3100 HT)
• Equipped with a large, rotatable, backlit 14-digit graphic display for optimal visibility in any mounting position
• Easy programming and commissioning with a menu and guide in 14 languages
• Compact or separate mounting possible with the same enclosure
• Enhanced diagnostics such as empty pipe monitoring and self-check of the unit
• Plug & Play modules allow easy replacement and commissioning of the transmitter on-site in just a few minutes
