Water and Oil for thermo Flow Switch
QLK400 is a flow transmitter with switch which could do real-time monitoring of liquid in the pipeline and it shall show the flow condition by several LED displayers. It can monitors following conditions:
Flow speed increasing or reducing, medium exists or not, the medium is moving or not.
It is used to protect idling pump and monitor the flow rate in the pipeline.
1.All stainless-steel case without movable components
2.Maintenance-free
3.Switching point could be set on site
4.LED displayer shows flow state and on-off state
