The Gems FT-210 series flow meters feature 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 years of service life.

The FT-210 series has a 1/4" (NPT or G) port for flow rates from 0.026 to 0.65 gpm (0.1-2.5 lpm). Basic accuracy is ±3% of reading. The FT-210 features a simple and reliable design suitable for pressures to 350 psig and temperatures to 212°F.
