Inexpensive Differential Pressure to measure Water Flow?
I need to measure water through a tube.
Specification: 0.25 ml/s - 1.5 ml/s (this can be relaxed to 0.40 ml/s- 1.15 ml/s)
I came across a few flow meters/sensors which could work but they're all pretty expensive (> 160 USD) - but was directed to pressure difference flow-sensors.
After the third page of google I couldn't find something small (which integrates well into a PCB fixture setup) and inexpensive (<150 USD).
Can anyone help?
Try flow-meters for coffermakers.
