A system for controlling temperature of intravenous fluids includes a thermal treatment device and a temperature sensing device to measure a temperature of the fluid flowing through the sensor. The temperature sensing device may simultaneously collect two temperature measurements. For example, the sensing device may include sensors that measure the temperature of the fluid at two disparate locations along the medical fluid line. Additionally, the sensors may measure the temperature of the fluid within the medical fluid line, as well as the ambient temperature outside of the line. The thermal treatment device includes a conduit configured to have a nonlinear flow path through the device. The thermal treatment device thermally treats fluid within the conduit to a desired temperature or range.
