The FTB-430 Series is a highly accurate and repeatable, hall effect turbine flow sensor designed for low flow OEM applications. This low cost, NSF Standard 61 listed flow sensor is ideal for water or beverage dispensing applications or any application with water based liquids. The 316SS shaft coupled with Polyoxymethylyne bearings allows for accurate measurements during quick dispensing cycles. The sensor’s standard power and output specifications make it easy to retrofit existing controllers.

Breaks easilyI bought a couple of these for use in an undergraduate lab. They all worked great at the start but within weeks they all stopped functioning. Water flowing at ~ 2-4 LPM was all that was run through them. I'd avoid this product unless you only need a small amount of data.
