FlexView FMA90 is a control unit for radar, ultrasonic and hydrostatic or universal 4-20 mA or HART level sensors. It connects up to two sensors simultaneously and provides 8 digital switching outputs for enhanced control. Available in field, DIN rail and panel housing variants, it ensures flexible installation in the field or control cabinet. Its robust design and intuitive touch operation make it ideal for water and wastewater as well as mining, minerals and metals applications.
FlexView FMA90 is suitable for a wide range of applications, providing clear visualization of measurement data and enhanced process control:
Open channel flow measurement
Remote water level and temperature monitoring
Pump control in water and wastewater treatment
Differential level measurement for rake control
Level monitoring in bulk solids storage
Crusher and conveyor belt monitoring
Benefits
Flexible use with up to two level sensors across multiple measurement technologies and seamless system integration via HART or Modbus TCP
High cybersecurity in line with IEC 62443 and Endress+Hauser ProtectBlue product security framework
Remote access and parameterization at hard-to-reach measurement points via Wi-Fi and an integrated web server
Intuitive operation thanks to the 3.5" color touch display operable with gloves
Fast commissioning with automatic sensor detection and configuration via HART and guided setup sequences
Kemira, a global chemicals company, needs accurate monitoring of level and temperature for polymer manufacturing. They use instrumentation with Bluetooth for safe and easy access to process data.
