The Gems FT-330 series are highly accurate and repeatable turbine flow sensors designed for low flow OEM applications. This low-cost meter is ideal for water or beverage dispensing applications or any application with water based liquids. The 316SS shaft coupled with Delrin bearings allows for accurate measurements during quick dispensing cycles. The sensor's standard power and output specifications make it easy to retrofit existing controllers. The FT-330 is NSF Std. 61 listed.

The FT-330 series has a 3/8" NPT port for flow rates from 0.2 to 4.0 gpm. Basic accuracy is ±2% of reading. The FT-330 features a simple and reliable design suitable for pressures to 200 psig and temperatures to 176°F.
