Review: works well - calibrationFactor = 6.9745; // millilitre calibrated over 2 litres
Review: Not for beer - It's really 5 stars. This flowmeter works with water, or I suppose with any other fluid it's rated for. The function is 100%. I got this for my kegerator, hoping to measure the amount of beer used from my keg. The issue I had is that this flow meter, is it agitates the beer, so only foam is coming out. Not the fault of the sensor per se, the sensor it self works perfectly. It does not work well with beer though, a heads up for anyone wanting to try it for that application.
