công tắc dòng chảy HFS-15, công tắc dòng chảy HFS-20, công tắc dòng chảy HFS-25, Flow switch HFS-15, flow switch HFS-20, công tắc dòng chảy hàn quốc HFS-25
FEATURES
- The paddle type SPDT HFS series are designed to provide excellent performance where accuracy, reliability, and rugged constructiuon are
required in liquid flow lines carrying water for any fiuid neither harmful to brass and prosphor bronze nor classified as a hazaardous fluids.
- They can be wired to close one circuit and open the other circuit when liquid flow either exceeds or drops below the adjusted flow rate.
- The HFS series are recommended for liquid pressure and temperature as mentioned below and must not be used on fluid bellow 0℃
- These series may be used on liquids with high salt or chlorine content but is not for use in hazardous atmospheres.
- Flow switches are designed for use only as operating controls.
- Since control failure can cause personal injury or property damage, users should use the monitoring system to alert control failure or the safety equipment.
