OMEGA’s FTB-420 Series features proven turbine
technology in a small package for low flow applications.
The turbine technology provides a highly repeatable
sensor ideally suited for measurement of either
volume dispensing and/or flow rate applications.
The small turbine reacts quickly to on/off dispensing
applications. Each sensor is 100% tested, ensuring
long service life.
