Flo-Gage Flow Switch Gas

Check up to five items to perform an action.

    Our general purpose flow switches (gas) reed switches make or break contacts by detecting the position of a magnet permanently attached to the lever mechanism on the flow indicator. Our reed switches can also be ordered for use in hazardous locations (Option IS), when fitted with LED's (Option LED) it provides viewing at a glance and easy field calibration.
