发明名称 |
An apparatus for dynamically determining vapor pressure in a pump, wherein a portion of pump fluid is diverted using valves and an evacuation pump for vapor pressure measurement. |
摘要 |
A method and system for dynamically determining a vapor pressure of a fluid passing through a pumping system by diverting a portion of the fluid from the pumping system into a chamber, isolating the diverted fluid from the pumping system, evacuating the chamber and measuring the vapor pressure of the isolated fluid. In another aspect of the invention, a temperature compensation device is included in the chamber to alter the chamber fluid temperature to insure that the chamber fluid temperature is substantially the same as the fluid in the pumping system.
