摘要: A moisture monitor apparatus for a fluid system. The apparatus includes a heater in fluid communication with the fluid system to heat the fluid in the fluid system. A microphone transmits sounds produced as the moisture vaporizes from heating and converts the sounds into electric voltage variations. The electric voltage variations are translated into quantitative data to determine the level of moisture in the fluid.

摘要: A viscosity measurement apparatus for measuring viscosity of a fluid under known pressure. A tube of known diameter and length allows the fluid to pass therethrough. A closed chamber is in fluid communication with the tube. A piston, sealably engaged with the chamber, may be moved by force of the fluid passing through the tube. A linear gauge measures the time required to move the piston. A mechanism is provided to reset the piston by forcing fluid back through the tube to empty the chamber to begin another measurement.
