Endress+Hauser FlexView FMA90 – Flexible Control for Level and Flow Measurement
The FlexView FMA90 is a versatile control unit designed to centralize measurement, visualization and process control for level and flow applications. It can connect up to two level sensors using different measurement technologies, including radar, ultrasonic, hydrostatic and universal 4–20 mA/HART sensors.
With a 3.5-inch color touchscreen, flexible I/O options and modern communication interfaces, the FMA90 provides a practical solution for applications where measurement data, control functions and system integration need to be handled in one device.
Flexible Measurement and Sensor Integration
The FMA90 can work with multiple sensor technologies and automatically recognize and map parameters for compatible sensors. This makes it suitable for applications where different measurement points or measurement principles need to be managed from a common control unit.
Key performance:
Sensor inputs: 1 or 2 × 4–20 mA/HART
Supported sensors: Radar, ultrasonic, hydrostatic and universal 4–20 mA/HART level sensors
Display: 3.5" TFT color touchscreen with backlight
Communication: Ethernet / WLAN options and Modbus TCP
Outputs: 2 × analog, relay options and open-collector outputs
Power supply: 100–230 VAC or 10.5–32 VDC
Ambient temperature: –40 to +60 °C
Mounting: Field, DIN rail or panel
Protection: Up to IP65 / NEMA Type 4X depending on housing configuration
Intuitive Operation and Remote Access
The color touchscreen provides clear local visualization of measurement values and process status. The display can also be operated while wearing gloves, which is useful for field installations.
For installations in difficult-to-access locations, WLAN connectivity and an integrated web server enable remote access and parameterization. Guided commissioning wizards also help simplify initial device setup.
Designed for Process Control
Beyond measurement display, the FMA90 can be used for a range of control functions. Its configurable outputs allow the device to support pump control, open-channel flow measurement, rake control, storm overflow monitoring and data logging.
Typical applications include:
Water and wastewater treatment
Open-channel flow measurement
Remote water level and temperature monitoring
Pump control
Differential level measurement
Bulk solids level monitoring
Crusher and conveyor belt monitoring
Flexible Installation for Different Systems
The FMA90 is available in field, DIN rail and panel-mounted versions, allowing the same control concept to be integrated into field installations, control cabinets or panel systems. The field housing can achieve IP65/NEMA Type 4X, while the panel version provides IP65/NEMA Type 4 protection at the front when installed in a cabinet door.
Secure and Connected Control
For modern automation systems, the FMA90 supports Modbus TCP integration and is designed with cybersecurity considerations aligned with IEC 62443 and the Endress+Hauser ProtectBlue product security framework.
