Modulating makeup fluid control systems and methods for same

Abstract

A method for maintaining a boiling rate of a base fluid can include a determination of a fluid level of a turbulated base fluid in a reservoir. The fluid level can be determined by measuring at least one first height of the turbulated base fluid above the fluid level with at least a first sensor. The fluid level can be determined by measuring at least one second height of the turbulated base fluid below the fluid level with the first sensor. The method can include the establishment of the fluid level of the turbulated base fluid. The fluid level can be established according to the measured at least one first and second heights. The method can include the graduated introduction of an input fluid into the reservoir. A control valve can gradually introduce the input fluid in proportion to the established fluid level of the turbulated base fluid.

The claimed invention is: 
     
         1 . A method for maintaining a boiling rate of a base fluid, comprising:
 determining a fluid level of a turbulated base fluid in a reservoir, wherein the fluid level is determined by:
 measuring at least one first height of the turbulated base fluid above the fluid level with at least a first sensor, and 
 measuring at least one second height of the turbulated base fluid below the fluid level with the first sensor; 
   establishing the fluid level of the turbulated base fluid according to the measured at least one first and second heights; and   graduating the introduction of an input fluid into the reservoir with a control valve in proportion to the established fluid level of the turbulated base fluid.
