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.
