Our flow controllers with Modbus RTU combine precise airflow monitoring with modern communication technology. They reliably detect flow velocities or volume flows in ventilation ducts and transmit the measured values digitally to building management systems. The Modbus interface enables simple integration, reduced wiring and access to multiple data points simultaneously. Depending on the model, functions such as temperature compensation, configurable switching outputs or automatic flow calculation are integrated - ideal for efficient HVAC systems and intelligent buildings.
