Abstract: A method of detecting a fault condition in an infusion process, the method includes receiving a programmed flow rate pertaining to a fluid infusion provided by an infusion device; determining, a first weight of an infusion container associated with the fluid infusion provided by the infusion device at a first time; determining a second weight of the infusion container at a second time; determining based on the first weight and the second weight, a determined flow rate of the fluid infusion provided by the infusion device between the first time and the second time. The method includes determining a difference between the determined flow rate and the programmed flow rate. When a magnitude of the difference between the determined flow rate and the programmed flow rate satisfies a predetermined threshold, by the processor: causing an output of the infusion device or the weight sensor to indicate the fault condition.
