I am looking for a datalogger solution from an arduino board and I have put my wish list below. We commission new mains and need to log both flow rates into the pipe work initially and then much lower levels of water whilst pumping water to raise pressure. Pressure must also be monitored. We need an adjustable data recording time of between 5 and 30 seconds to log pressure and flow. Ideally we...

I have a circuit that isn't working as it should. This circuit should convert a sin wave to a square wave, then the frequency of the signal should be divided by 10 using the HC4059. The signal looks very nice all the way until the HC4059. After that IC, the signal looks terrible from varying frequency. I need to know why this is happening and how to fix it.
