Flow liquid meter sensor target flow switch controller HFS-25
Introduction
This TYPE of HFS flow switch is mainly used in water treatment system, central air conditioning, water cooling unit and other fields, suitable for water. Glycol and any other liquid that has no corrosive effect on brass and phosphor copper and has effect on sealing performance.
Working principle
When the flow rate exceeds the set value, the fluid pushes the blade and drives the microswitch at the top through a mechanism in the HFS-25 flow switch. Its single pole double throw switch contact (SPDT) enables one circuit to be turned on while cutting the other circuit. The flow switch is usually used where interlocking or "cut-off" protection is required. The number of blades can be adjusted and the blade length can be trimmed to meet the needs of different pipe diameters and flow rates.
Specification
Working pressure: 10 bar Working medium: air, water and oil Contact life: 100,000 times Ambient temperature: -15... 80 ℃ Medium temperature: 0... 110 ℃ Interface thread: G1 "tube screw Weight: 0.50 kg |
Hfs-25 target flow controller, flow switch, flow switch only for liquid medium above 0℃, can also be used for high salt liquid, but not classified as dangerous liquid.
Akhfs-25 target flow controller, flow switch, flow switch can be installed outdoors, can be installed horizontally or vertically in the pipeline.
Hfs-25 target flow controller, flow switch, flow switch only for operational control. It is necessary to strengthen the responsibility of the installation personnel and limit control, alarm monitoring system to prevent the occurrence of control failure.
The hfs-25 has a maximum pressure of 1600Kpa and a pressure resistance of 1500V/1minute. Its function is to protect the site with "cut-off flow".
