Reed Switch Flow Meter

The rotating magnet makes a reed switch open 4.

Reed switch flow meter.

For decades kobold has been a world leader in process measurement and control solutions. It is closed with a frequency proportional to the flow rate by a serially integrated magnet within the counter and opens itself automatically again. As a passive pulser the reed sensor is designed as a potential free normally open contact. This system uses two reed switches to detect the rotating magnet inside the meter.

There s a pipe through which liquid flows 1 with a paddle wheel mounted inside it 2. We offer one of the industry s broadest lines of sensors switches and transmitters to measure and control flow pressure level and temperature. The magnet is confined in the casing and drives the external gear counter through the magnetic flux. They all attach to the meter with a single screw and positioning is fool proof due to the shape of the switch.

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. A typical reed switch flow meter works something like this. These dry contact reed switches are hermetically sealed and have a 5 foot cable lead.
