Feature
●High Temperature Resistant : This control switch adopts stainless steel leaf blade and plastic shell, with strong temperature adaptability of 0℃~ 120℃/32~248℉, and can withstand high pressure of 1.0Mpa, durable in use.
●High Temperature Resistant : This control switch adopts stainless steel leaf blade and plastic shell, with strong temperature adaptability of 0℃~ 120℃/32~248℉, and can withstand high pressure of 1.0Mpa, durable in use.
●Application : This switch is widely used for water treatment system, central air conditioning, water cooling unit and fire protection system.
●Suitable Media : The flow switch is mainly used to measure the dynamic state of the liquid flowing through the pipeline, including water, ethylene, and other liquids that have no corrosive effect on copper.
●Feature : The flow control value is adjustable and the action repetition point is stable. Interface dimensions: 1/2in (HFS-15), can fits most of equipment.
●Note : The HFS flow switch shall not be used in pipelines where the liquid temperature drops below the freezing point of the liquid. The HFS flow switch cannot be hit by water. If there is a quick closing valve in the downstream of the flow switch, the throttle must be used.
Description
Matters needing attention:
- The flow switch can be installed in the horizontal pipe or the vertical pipe with the upward direction of liquid flow, but it cannot be installed in the pipe with the downward direction of liquid flow. Gravity should be considered when installing in piping above the flow direction of the fluid
- The flow switch must be installed on the straight pipe of the section, both sides of which are short of the straight stroke of 5 letter pipe diameter. At the same time, it should be noted that the direction of liquid flow in the pipe must be consistent with the direction of arrow on the switch shell.
- When installing wiring, please pay attention to the following matters:
- it is absolutely forbidden to impact the wrench on the switch bottom plate, resulting in deformation failure of the flow switch;
- when wiring, it is absolutely forbidden to adjust any screws other than micro switch terminals and grounding screws. It should be noted that the micro switch wiring cannot be usedt
- he blade of the flow switch cannot contact with the inner wall of the pipe and other throttles in the pipe, otherwise the switch cannot be reset normally.
