Abstract: A dump valve system includes an automatic dump valve connected downstream from the liquid discharge and configured to adjust the flow rate of the liquid through the liquid discharge, a float assembly, a level controller and a control module. The float assembly includes a float inside the vessel and a float arm connected to the float. The level controller includes a linear position sensor assembly configured to output an electric signal and an internal drive mechanism between the float arm and the linear position sensor assembly, where the internal drive mechanism translates a rotational movement of the float arm into a linear movement of the linear position sensor assembly. The control module is configured to adjust the operation of the automatic dump valve based on the output from the linear position sensor assembly.
