Flow monitor 626 1"- 8"

• In heating systems, the flow monitor has the task of switching off the burner if the heat transfer fluid no longer circulates or only circulates insufficiently.
• The changeover contact allows any device to be switched on or off when the response flow rate is reached.
• Installation into the pipe is done by welding on a DN 25 (1") socket.

• Connection: DN25 (1")
• Temperature medium max.: +120°C
• Medium temperature min.: 30°C
• Maximum ambient temperature: +55°C
• Voltage: 240 V
• Protection class: IP 54
• Contact: Changeover switch 15 (7) A
• Maximum operating pressure: 10 bar
• For pipe sizes: DN25 (1") DN200 (8")
• Approval: CE
