This has included a flow meter on the outlet (for exactly the points that you make above) and a pressure switch to determine if the aeration pump is providing the correct pressure. One of the more interesting thoughts I've entertained is to add a vibration sensor to the aeration pump which should be able to determine if a valve is failing.D3noobhttps://www.blogger.com/profile/03091573479428198379noreply@blogger.comtag:blogger.com,1999:blog-279772059074318326.post-88420127201635377582023-01-28T13:19:57.829-08:002023-01-28T13:19:57.829-08:00A huge thank you for documenting this.

A treasure trove of information :)<br /><br />The pumps in septic tanks are usually low-tech and controlled by float switches in the tanks - so you have to detect the current flow, not the voltage supplied to them. Capturing time-series data and knowing when the pumps are switching on/off, and thus the run duration, provides data which you can use to gauge distribution field and dripline health etc. <br /><br />The frequency of pump runs can be used to determine flow (litres per hour/day etc) because you will be able to calculate how many litres are moved per run (irrespective of how long that takes). Use the difference in float height between on/off events and the circumference of the tank to calculate volume moved.stephenhttps://www.blogger.com/profile/07183941906251336171noreply@blogger.com
