Flow Switch

They are used in sprinkler system to transmit electrical information due to the flow, when a sprinkler head gets activated. Delay units are available to prevent false alarms. Delays up to 90 seconds are possible.

Hi DV, thanks for the informative video, i hav a question, if u happen to install the flowswitch in a reverse position, will it still work? Or can a flowswitch work in a reverse flow?

[@DuyarVana1965]

Hello Alfie, Flow Switch will not work in reverse position. Installation should be made according to the flow direction. Thanks for following us.

@@DuyarVana1965 hi DV. Thanks. But just wondering, is there a built in check valve in it? where it restricts a reverse flow? Reason why i asked is because consultants here are not consistent, some of their detailed drawing shows additional check valve while others does not.

[@DuyarVana1965]

@@alfiegm2137 Hello again, Thanks for your response. There is no check valve in flow switch. There is no mechanism in the flow switch of any brand to prevent reverse flow. When the flow switch is connected only according to the flow direction, when there is a water flow in the system it detects and generates a signal.

[@alfiegm2137]

@@DuyarVana1965 thanks DV. That makes sense, since activation of one floor flowswitch in a series of typical floors flow switches could mean multiple flow detections of floors, even though not all floors has fire, if it detects reverse flow.

Hi, Good day. I found your channel has a good impact to my study while I'm learning here in our Plant Site as Junior Engineer. I'm very glad to found this channel and help me to understand the every part of sprinkler system. Hope, if you mind to share useful file (e.g. powerpoint or video animation) for the entire sprinkler, atleast for wet sprinkler system, from fire pump up to sprinkler heads. Thank you very much.

[@DuyarVana1965]

Can you send us an email. We want to send sprinkler system animation videos and documents.

The video says "In case of fire, Indicates the location of the fire by sending an electrical signal to the system". This is incorrect. The device does not do this

Usually each flow switch cover 1 floor of the building, so it inlu tell you which floor, not the exact location ( the specific room or (corridor

nice 3d animation

Thanks for watching.

thanks a lot

Thanks for watching.

[@mahmoudmagdy8383]

can anyone demonstrate to me how does it detect the fire location cuz i didn't get it from the animation

[@hsn000hsn2]

Each flow switch cover specific area (like one floor of the building). So it tells you the alarm is in the area covered by this flow switch, not the exact location.
