Liquid Flow Meter - Plastic 1/2" NPS Threaded

Now available from PMD Way are these great value plastic liquid flow meters. They use a hall effect sensor to output a pulse every time the internal sensor rotates.

Your microcontroller (etc) then counts the pulses to determine flow rate. 1 litre of water is 450 pulses. Free delivery, worldwide.
