Optimized control of oilfield separator level and dump valves

A dump valve system for controlling a level of a liquid inside a vessel that includes a liquid discharge, the dump valve system comprising:

• an automatic dump valve connected downstream from the liquid discharge and configured to adjust a flow rate of the liquid through the liquid discharge;
• a float inside the vessel;
• a float arm connected to the float;
• an inclinometer attached to the float arm and configured to output an angular disposition signal representative of an angular disposition of the float arm;
• flow meter configured to measure the flow rate of liquids discharged from the automatic dump valve and output a flow rate signal representative of the measured flow rate;
• and
• a control module configured to adjust an operation of the automatic dump valve in response to the flow rate signal and the angular disposition signal.

• a float inside the vessel;
• a housing attached to the vessel;
• a pivot inside the housing;
• a float arm connected to the float, wherein the float arm extends through the vessel into the housing, and wherein the float arm is connected to the pivot such that the float arm comprises:
• a proximal portion between the pivot and the float;
• and
• a distal portion outboard of the pivot;
• an inclinometer attached to the float arm and configured to output an angular disposition signal representative of an angular disposition of the float arm;
• a flow meter configured to measure the flow rate of liquids discharged from the automatic dump valve and output a flow rate signal representative of the measured flow rate;
