An injector system for use in injecting a fluid into a patient includes a communication system adapted to receive data from at least a first sensor that measures a value first variable. The communication system is also adapted to receive data from a calibrated sensor that measures a value the first variable. The injector system further includes a calibration system adapted to calibrate output from the first sensor in response to output from the calibrated sensor. An injector for use in injecting a fluid into a patient, includes a first sensor that measures a value first variable, a communication port adapted to receive data from a calibrated sensor that measures the value the first variable, and a controller adapted to compare data from the calibrated sensor with data from the first sensor and to calibrate output from the first sensor. The devices, systems and methods of the present invention are applicable to systems other than injection systems. For example, a method for calibrating a system (for example, an injector system) includes: placing a calibrated sensor in communication with the system; making a measurement of the value of at least a first variable with the calibrated sensor; transmitting the measured value from the calibrated sensor to the system via a data communication system in operative connection between the calibrated sensor and the system; making a measurement of the value of the first variable with a sensor of the system at approximately the same time as the measurement made with the calibrated sensor; comparing the value of the first variable measured with the calibrated sensor with the value of the first variable measured with the system sensor; and calibrating the output of the system sensor at least in part based upon the comparison.
