| Title of Invention | HIGH PURITY FLUID DELIVERY SYSTEM |
|---|---|
| Abstract | A fluid delivery system includes a flow control device and a Coriolis mass flowmeter(112) in fluid communication with the flow control device.(110).The Coriolis flowmeter has a flow−tube made of a high−purity plastic material, such as PFA, making the delivery system suitable for high purity applications. A controller (114)provides a control output signal to the flow control device(110), which may comprise a pinch valve(120), so as to vary the flow control device output in response to a setpoint signal and measurement signals received from the flowmeter.(112). |
