1. A vessel tracking system for tracking a vessel mover in a liquid handler system, the liquid handler system comprising a track system, the vessel tracking system comprising:
a sensor assembly associated with the track system, the sensor assembly comprising a plurality of Hall effect sensors positioned along the track system, wherein the Hall effect sensors are configured to detect a magnet positioned with the vessel mover, wherein the Hall effect sensors are positioned such that a signal from each of the Hall effect sensors does not overlap beyond a threshold with an adjacent Hall effect sensor that is less than 6 dB of a sensor peak value; and
a control system coupled to the sensor assembly, the control system configured to:
receive a signal from each of the plurality of Hall effect sensors,
determine which of the plurality of Hall effect sensors the vessel mover falls within a sensing range of to define a sensing Hall effect sensor,
map the signal from the sensing Hall effect sensor to a function, wherein the function is configured to relate a strength of the signal to a distance with respect to the sensing Hall effect sensor, and
determine a position of the vessel mover based on the mapping of the signal from the sensing Hall effect sensor to the function.
