NSF批准的涡轮机 FTB-430 Series 1年保修 新产品! NSF批准的涡轮机 FTB-430 Series:NSF批准的涡轮机 FTB-431 Measures Flow Rates from 0.2 to 4 GPM Lightweight Plastic Design for Multiple Mounting Positions High Accuracy: ±2% of Reading High Repeatability: ±0.5% of Reading Over-Molded Electronics with Integral Cable Strain Reinforcement 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.
