Product Description

Overview
QLK400 is a thermal flow transmitter with a switch that could do real-time monitoring of liquid in the pipeline and it shall show the flow condition by several LED displayers. It can monitors the following conditions: Flow speed increasing or reducing, medium exists or not, the medium is moving or not. It is used to protect the idling pump and monitor the flow rate in the pipeline.
