Abstract: A method to predict time and/or distance remaining before a fluid system reaches a low fluid level includes determining a fluid level of the fluid system before execution of a fluid request command; determining an amount of time that fluid from the fluid system was spent in response to execution of the fluid request command; and determining external inputs that may affect a frequency of the fluid request command. A calculation of the risk of a low fluid level event occurring is made by inputting the current fluid level of the fluid system, the amount of time that fluid from the fluid system was being spent, and the external inputs that may affect the frequency of the fluid request command into a remaining useful fluid prediction model. A low fluid level alert is provided when the remaining useful fluid prediction model determines a low fluid event may occur.
