BFS-50 is a flow switch that features an adjustable switching range and is suitable for use in liquid and gaseous media.
The BFS-50 is a flow monitor designed for liquid and gas media with a continuously adjustable set‑point and robust construction suitable for any installation position. Key features include a large switching range, low hysteresis, high functional safety and accuracy, and a piston‑valve design that is resistant to contamination.
The sheet lists technical data such as measurement principle, accuracy, materials, electrical connection, contact load, operating temperature, flow ranges for water, process connection sizes, dimensions for each DN size, and order numbers. It also notes ordering requirements for viscous or gaseous media. This manual is written in German.
