FLOW SENSOR FOR PNEUMATIC SYSTEMS AVENTICS AF2 FROM EMERSON: MONITORING, SAVING AND ENERGY OPTIMIZATION
Emerson’s Aventics AF2 flow sensor, for which we are an authorized dealer, is a state-of-the-art sensor that helps optimize energy consumption by going to monitor air leakage in pneumatic systems.
Introduced in 2019, Emerson’s Aventics AF2 IIoT flow sensor is still an innovative system that improves energy performance and prevents leakage, thus avoiding excessive costs in case of failure and/or malfunction.

Industrial Automation and Industrial Internet of Things
Internet of Things: increasingly intelligent tools that help to improve, by automating, some work processes. Nowadays, Emerson’s AF2 flow sensor is an indispensable device for more varied industries, given also the rising energy costs. A necessary support, useful for detecting air leaks and possible malfunctions, thus going on to prevent not only breakdowns but also excessive air consumption, which would then affect costs.
A high-tech sensor that constantly monitors air consumption in pneumatic systems and ensures compliance with the DIN ISO 50001 Energy Management standard. The Aventics AF2 flow sensor is suitable for all common applications and industries such as food and beverage or packaging.
Andreas Kliewe, energy management expert for Emerson’s mechanical and industrial automation business says:
“The Aventics AF2 series flow sensor is particularly suitable for companies that want to control and optimize their energy use…The device records the flow rate and consumption of compressed air in a system, sending a signal to the control unit when pre-set levels are exceeded. This helps avoid excessive energy losses and allows for quick action in case of problems. After all, the share of unit energy costs in the gross production value is two to three percent; therefore, it is worth saving money here.”
AF2 Aventics flow sensor features from Emerson
The modular construction with which this sensor is made allows for easy installation, and considering its small size, it can be installed even in places with limited space.
We will find an organic light-emitting diode (OLED) display on the AF2 sensor that provides local indication of all relevant operational and diagnostic data.
The flow sensor is available in two versions:
- NO version – Normally open
- NC version – Normally closed
Analog outputs can be switched with a 4 to 20 mA signal.
Another communication option, which customers can use with existing control units, is the sensor’s IO-Link function and Ethernet interface.
Directly integrated we will find the preferred communication protocols for Industry 4.0:
- MQTT – Message Queuing Telemetry Transport
- OPC UA – Open Platform Communications Unified Architecture
The AF2 sensor has a Web-based dashboard that shows real-time data to users .
