The DigiFlow DFS-20 Series Teflon® flowmeters provide flow sensing capabilities in a wide variety of end-use and OEM applications, including corrosive aqueous liquids. Utilizing a rotor which, using a reflected infrared beam, generates a digital signal. The DFS-20 series offers an accurate, economical, and flexible design to meet many customer requirements. In either monitoring or flow controlled applications, the DFS-20 series can measure flow rates and totalize.

• Three ranges from 0.09 - 35 litres/minute (.025 – 9.2 GPM).
• Wetted surfaces of PFA Teflon® with ruby glass bearing.
• Outer housing of PFA or SS.
• Accuracy within 1% or better (0.15% repeatability).
• Low pressure drops.
• Infrared signal pickup.
• Mount in any position without flow straighteners.
• Interchangeable/Disposable rotor assembly option.
• CE mark approved.
• Fiber optic signal transmission option.

The DFS turbine flow meter can monitor flow rates and/or total quantities when connected to a basic counter. In conjunction with a stand-alone controller or interfaced with process control or general purpose computers, the DFS is an integral part of flow controlled processes. In end-use, or in OEM applications, the DFS is a key part in a systems approach to a wide range of monitoring and controlling applications including:

• Semiconductor and other high purity processes.
• Dosing of chemicals into main stream flows for agricultural, water treatment, and other processes.
• Additive injection in chemical processes.
• Monitoring/Controlling fuel flows.
• Medical/Pharmaceutical equipment.
