Reed Switch Flow Meter

The magnet is confined in the casing and drives the external gear counter through the magnetic flux.

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. 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.

As a passive pulser the reed sensor is designed as a potential free normally open contact. There s a pipe through which liquid flows 1 with a paddle wheel mounted inside it 2. The upcounter will be added up by one the tidub33 december 2015 flow measurement with reed switches and ble. They all attach to the meter with a single screw and positioning is fool proof due to the shape of the switch.

The rotating magnet makes a reed switch open 4. It is closed with a frequency proportional to the flow rate by a serially integrated magnet within the counter and opens itself automatically again. For decades kobold has been a world leader in process measurement and control solutions. As the liquid flows the paddle spins and makes a magnet rotate 3.
