The goal is to have a non-invasive flow meter that I can clamp over hydraulic lines.

As a student of hydraulics, I ended up looking and poking around for a good way to make an ultrasonic flow sensor with Arduino and possibly the hc-sr04. Not married to either idea.

So, I admit, I know nothing, but is it possible to do this?
Is there an easier way?

  • $\begingroup$ The HC-SR04's ultrasonics are sound waves in air and might not couple well into a hydraulic line without some special adapters $\endgroup$ – James Waldby - jwpat7 Feb 14 '16 at 18:26
  • $\begingroup$ Thanks, I know my post wasnt that specific. I'm mostly looking for just a general starting point. The biggest one being, which ultrasonic detectors are applicable. I don't know much of anything about this, but wanted to see what info was out there. $\endgroup$ – Yippeethemagician Feb 15 '16 at 2:37
  • $\begingroup$ I'm going to migrate this question to robotics as it's more relevant there. $\endgroup$ – Avamander Feb 15 '16 at 9:45
  • $\begingroup$ Welcome to robotics Yippeethemagician, but this is looking like a shopping question. We prefer practical, answerable questions based on actual problems that you face, so it is a good idea to include details of what what you would like to achieve, what you have tried, what you expected to see & what you actually saw. Take a look at How to Ask & tour for more information on how stack exchange works. Please work through the Robotics question checklist & edit your question to make it clearer. $\endgroup$ – Mark Booth Feb 15 '16 at 12:22
  • $\begingroup$ Your other question has just been brought to my attention, so as that one is better phrased, I have closed this as a duplicate of it. $\endgroup$ – Mark Booth Feb 15 '16 at 14:44
