Reed switch based flow sensors are built with a paddle having multiple magnets or a single multi pole magnet that continuously triggers the reed switch to generate a square wave output that can be translated to volume of fluid.
Reed switch flow meter.
A flow sensor or a flow meter is a device used to quantify the volume of fluid passing through a point in a pipe.
The upcounter will be added up by one the tidub33 december 2015 flow measurement with reed switches and ble.
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 rotating magnet makes a reed switch open 4.
There s a pipe through which liquid flows 1 with a paddle wheel mounted inside it 2.
This system uses two reed switches to detect the rotating magnet inside the meter.
A typical reed switch flow meter works something like this.
They all attach to the meter with a single screw and positioning is fool proof due to the shape of the switch.
We offer one of the industry s broadest lines of sensors switches and transmitters to measure and control flow pressure level and temperature.
These dry contact reed switches are hermetically sealed and have a 5 foot cable lead.
The magnet is confined in the casing and drives the external gear counter through the magnetic flux.
For decades kobold has been a world leader in process measurement and control solutions.
