Description:
QFS-400 flow switch is a kind of real-time monitoring measurement instrument that used for liquid flow in pipeline .It adopts full metal jacket, no moving parts, output continuously adjustable, compact structure. 6 LED real time display the state of flow and output. Convenient installation, suitable for various pipe diameters. Widely used in hydropower and other pipeline fluid flow monitoring industry.
It can monitors following conditions:
Flow speed increasing orreducing,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.
Model: QFS-400
Range:1~150cm/s(water),3~300cm/s(oil),200cm/s~3000cm/s(gas)
Feature:
High accuracy, good stability, long working life and high reliability
Small in size,convenient installation
All stainless steel case without movable components.
Maintenance free
Switching point could be set on site
LED display shows flow state and on-off state
Dimensions :( unit: mm)
Electrical connection:
Technical Specifications:
Installation 1. The wetted parts need to immersed in fluid.Installation in small diameter pipeline to ensure that the probe can't contact with pipe's inner wall.
2 .When the fluid can not completely fill the pipeline, products should be installed in the bottom of the pipe. (Figure 1)
3. If there may be sediment in the pipeline, please products installed in the pipeline side wall, horizontal mounting (Figure 2), to avoid the air and sediment
4.Installation in a straight pipe close to bend or intersection place, the pipe length should not be less than 4 times the diameter of pipeline.
