Reed Switch Flow Meter

This system uses two reed switches to detect the rotating magnet inside the meter.

Reed switch flow meter.

It is closed with a frequency proportional to the flow rate by a serially integrated magnet within the counter and opens itself automatically again. The upcounter will be added up by one the tidub33 december 2015 flow measurement with reed switches and ble. There s a pipe through which liquid flows 1 with a paddle wheel mounted inside it 2. As the liquid flows the paddle spins and makes a magnet rotate 3.

A flow sensor or a flow meter is a device used to quantify the volume of fluid passing through a point in a pipe. These dry contact reed switches are hermetically sealed and have a 5 foot cable lead. The rotating magnet makes a reed switch open 4. For decades kobold has been a world leader in process measurement and control solutions.

A typical reed switch flow meter works something like this. We offer one of the industry s broadest lines of sensors switches and transmitters to measure and control flow pressure level and temperature. The cable has 2 wires for single pulse switches and 3 wires for double pulse. They all attach to the meter with a single screw and positioning is fool proof due to the shape of the switch.
