Utilizing a rotor which, through use of an infrared beam, generates a digital signal, the DigiFlow concept offers high accuracy, low cost, and a flexible design to meet customer requirements. In either flow controlled, or monitoring applications, the DFS series meters can measure flow rates and total quantities.
Housing of high quality polymers or machined metal.
Low pressure drops
Friction-free fluid bearings yielding long life.
Compatible with most acids and bases.
Turn down ratios of up to 64:1
Mount in any position without flow straighteners.
Infrared signal pick-up.
Resolution of up to 65,000 pulses/litre (246,000/gallon).
Systems & Applications
Connected to a basic counter, the DFS meter can monitor flow rates and/or total quantities. 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, including those requiring disposable components, the DFS is a key part in a systems approach to a wide range of monitoring and controlling applications including:
Dosing of chemicals into main stream flows for agricultural, water treatment, and other requirements.
Additive injection in chemical processes.
Monitoring/Controlling fuel flows.
Monitoring pulse feed pump flows.
