<p>A method and apparatus for monitoring and analyzing the performance of a recirculation control system are disclosed. According to the invention, the pressure of the liquid passing through the control system is measured directly by pressure and differential pressure transducers at the main inlet, main outlet, and, within the regulation means of the control system. Where the means for regulating the flow of liquid to the recirculation outlet comprises a piston within a piston chamber, the pressure of the liquid within the regulating means is measured in the piston chamber. The pressure data is analyzed to determine valve performance.</p> |
