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.
