Micro flow meter - $60

QR Code Link to This Post

This tiny electronic flow meter will measure liquid flow between 3 and 30 gallons per hour, displayed in milliliters per minute.

From Omega Engineering, the model is FTB323D.

Almost 20 years old but still works great.

I use two 9V batteries to operate it, or can be hard wired.
