S409 Flow Direction Switch

S409 Flow Switch

The S409 is an insertion type flow sensor with standard G1/2″ male thread and 2 relay outputs intended for indication of flow direction. The sensor works on the calorimetric principle and suitable for all gases compatible with the wetted materials.

S409 can be used as a simple flow switch or when combined with other SUTO flow meters such as S 400, S401 and S450 will activate or deactivate the flow measurement for each flow direction. This ensures that the consumption figures recorded for bidirectional flow are accurate for each direction.
