Flexible Control for Level and Flow Applications
The Endress+Hauser FlexView FMA90 is designed for applications where measurement data needs to be clearly displayed, managed and used for process control.
It can connect up to two level sensors and supports multiple measurement technologies, making it suitable for different level and flow applications without requiring a separate control concept for every measurement point.
The FMA90 is particularly well suited to water and wastewater, mining, minerals and metals, as well as other applications where dependable measurement and practical process control are important.
Clear Information at the Point of Operation
The optional 3.5-inch TFT color touch display provides a clear interface for onsite operation.
The display can be operated with gloves, while guided setup sequences help make commissioning more straightforward. Automatic sensor detection and parameter mapping are also available for supported sensors, helping reduce unnecessary setup work.
Designed for Flexible Sensor Integration
The FMA90 can be used with selected Endress+Hauser level sensors, including:
- FMR10B
- FMR20B
- FMR30B
- FMX21
- FMU30
The system supports 1 or 2 × 4–20 mA/HART inputs, allowing measurement signals to be brought together within the same control unit.
Remote Access Makes Difficult Measurement Points Easier to Manage
When the measurement point is located somewhere that is difficult to access, the FMA90 can provide WLAN connectivity and an integrated web server for remote access and parameterization.
This is particularly useful for remote water level monitoring and other installations where regular onsite access is inconvenient.
Flexible Communication and Output Options
The FMA90 is designed to integrate into different control architectures.
Depending on the selected configuration, communication and output options include:
- HART or Modbus TCP
- 1 or 2 × analog outputs
- 1 or 5 relays
- 1 or 3 open collector (NPN) outputs
This gives the FMA90 enough flexibility to handle both measurement visualization and practical control functions within the same installation.
A Practical Choice for Different Installation Environments
The FlexView FMA90 is available in field-mounted, DIN rail and panel-mounted versions, allowing the same control concept to be adapted to different installation conditions.
The field housing is available with IP65 / NEMA Type 4X protection, while the DIN rail version is rated IP20. The panel-mounted version provides IP65 / NEMA Type 4 at the front and IP20 at the rear when installed in a cabinet door.
Built for Real-World Process Applications
The FMA90 is not limited to simply displaying a level value. Its combination of sensor integration, communication, remote access and control functions makes it useful where measurement data needs to become part of the actual process.
Typical applications include:
- Open-channel flow measurement
- Pump control
- Remote water level and temperature monitoring
- Differential level measurement for rake control
- Storm overflow basin monitoring
- Level monitoring in bulk solids
- Crusher and conveyor belt monitoring
