I understand this is an older reply but I was wondering if you had code posted somewhere that contained basic flow meter sensor measurements/integration? I'm a newbie learning the basics now but intend on working on that use case. I don't see it in any of the example projects, unfortunately!

In fact I've implemented a flow meter with nRF52 - but it didn't need a very high level of optimisation, and was using a LiPo battery. If you need help with the flowmeter part, you can message me.

Hi, thanks for the pointer, sounds very interesting for other ideas I have, where sensors can be activated, measured and deactivated upon request. In water totalizer case instead, I have to deal with flow sensors, made by third parties, which are always on and continuosly measure the water flow. I know these sensors emits pulses, thus I need a way to count these pulses using Nano in a very low-power way.

Take a look at the solar sensor beacon Nordic example - github.com/.../
