    Abstract: Syringe systems and flow control systems configured to detect information associated with a liquid material are described. The syringe systems may include a syringe body for housing the liquid material and an injector piston for expelling the liquid material out of the syringe through a discharge outlet at a distal end of the syringe body. Components of the syringe, such as an injector piston, may include sensors configured to measure and/or detect a property of the liquid material, such as concentration, pH, or radioactivity. The flow control system may include a pinch valve and a platen arranged about a fluid delivery channel. Flow within the fluid delivery channel may be controlled by increasing (squeezing the fluid delivery channel) or decreasing the distance between the pinch valve and the platen. Components of the flow control system may include detectors configured to detect properties of fluid in the fluid control channel.

    Abstract: Methods and systems for dispensing a fluid using an automated fluid delivery system are disclosed. A pump may be configured to force an aliquot of fluid into a fluid delivery channel. A processor may receive values of a property for the aliquot and the source of the aliquot. The processor may use the values to determine the volume of the aliquot. The determined volume is compared by the processor against an expected volume to establish the amount of fluid being pumped by the pump per unit, such as time or revolutions. The processor controls operation of the pump to dispense a predetermined dose based on the amount of fluid being pumped by the pump per unit.
