Display / Indicator FMA90
Brand: Endress+HauserField of application
FlexView FMA90 is a control unit for radar, ultrasonic and hydrostatic or universal 4-20 mA level sensors. It connects up to two sensors simultaneously and provides 8 digital switching outputs. Available in field, DIN rail and panel housing variants, it ensures seamless installation in field and control cabinet environments. Its robust design and intuitive touch control make it ideal for versatile applications in the Water, Wastewater & Waste sector and utility operations across all industries.
FlexView FMA90 is suitable for a wide range of applications:
- Open channel flow under changing weather conditions
- Rake control with occurring suspended solids or sediments
- Storm water basin in remote measuring locations
- Pump control in narrow installation conditions
Key Benefits
- Flexible use with up to two level sensors across multiple technologies
- High cybersecurity due to integrated software features
- Remote access to hard-to-reach measurement points thanks to Wi-Fi connectivity
- Ease of use thanks to intuitive 3.5" color display with touch control operable with gloves
- Fast commissioning with guided setup sequences, tutorials and automatic sensor detection
