Patent ID: RE43288

Claim:
A fluid delivery system, comprising: a reservoir having an inlet for receiving a gas to pressurize the reservoir and an outlet for dispensing fluid contained in the reservoir , with the reservoir including a flexible liner that holds the fluid and prevents the gas from passing into the fluid delivery system ; a first flow control device connected to the reservoir inlet; a first pressure transmitter connected to the reservoir inlet, the first pressure transmitter providing an output a reservoir inlet pressure signal; a second flow control device in fluid communication with the reservoir outlet to control fluid flow out of the reservoir; a second pressure transmitter connected to the reservoir outlet, the second pressure transmitter providing an output a reservoir outlet pressure signal; a Coriolis mass flowmeter in fluid communication with the second flow control device, the Coriolis flowmeter having a flow-tube made of a high-purity plastic material, the Coriolis flowmeter providing an output signal a mass flow rate output signal of a reservoir output flow from the reservoir and providing a density measurement for the fluid ; a controller receiving a setpoint signal, the controller receiving the output signals reservoir inlet pressure signal from the first and second pressure transmitters and pressure transmitter, the reservoir outlet pressure signal from the second pressure transmitter, and the mass flow rate output signal and the density measurement from the Coriolis flowmeter and providing control output signals to the first and second flow control devices to vary the pressure of the reservoir and the flow rate of fluid from the reservoir.
