Flow monitor model 626, DN25 (1")

• In heating systems, the current monitor is tasked with switching off the burner if the means of delivery is no longer circulating, or only to an insufficient degree
• If needed, the change-over contact allows any device to be switched on or off when reaching the response flow
• Installation in the pipe takes place by welding on a joint DN 25 (1")

• Connection: DN25 (1")

• Medium temperature min.: -30°C
• Ambient temperature: max.: +55°C
• Voltage: 240 V
• Protection type: IP 54
• Contact: Toggle switch 15 (7) A
• Max. operating pressure: 10 bar
