Reading liquid flow may not appear to be such a challenge to the embedded systems engineer. It certainly seems easy enough to do, however, as the saying goes, 'the devil is in the details'. In order to achieve true scientific grade liquid flow readings you simply cannot just count pulses.

The FLO-30 Flow Meter Circuit has been designed around quality components. The flow meters that the FLO-30 can interface with are of the highest quality. The firmware on the FLO-30 Flow Meter Circuit is a very fast, real time operating system capable of managing the complex timing events needed to accurately read and report flow rates without ever missing a beat.
