Flow switch

Switches from a volume flow of approx. 1.5 litre/min. Installation: vertical with flow from bottom to top. External thread and conical face union available as 3/4” or 1” version. Permissible temperature range 0°C to +80 °C.

The flow switch STS03-AC has been optimised and cleared for use with high-efficiency pumps. Asynchronous pumps (up to 110W) have shown functional in the lab. For use with other consumers (relays, valves etc.), explicit permission from the Technische Alternative company must be given.

NEW: STS03AC replaces STS02AC
