A piston-type differential pressure gauge provides an electronic output for remote monitoring. A linear potentiometer, in communication with a magnetic portion of the piston of the gauge, tracks the location of the piston. Resistance change in the potentiometer can be used by an electronic circuit to provide the electronic output of the differential pressure remotely to a data acquisition system or control electronics.

A separator cartridge includes a support tube formed of a perforated strip of metal configured to normally have a first diameter and a spaced array of hexagonal apertures formed therein and a substantially cylindrical screen member having a diameter less than the first diameter of the support tube, wherein a diameter of the support tube is decreased from the first diameter to a diameter less than the diameter of the screen member to be received in the screen member, and wherein the support tube causes the screen member to be maintained in a substantially taut manner.

A system for collecting a sample of fluid from a fluid source and reintroducing the sample of fluid to the fluid source is disclosed. The system includes a pump in fluid communication with the source of fluid, a filter vessel in fluid communication with the pump and the source of fluid to receive a flow of fluid from the pump and substantially eliminate contaminants from the fluid flowing therethrough, and a fluid reservoir in fluid communication with the pump, wherein the fluid is directed from the pump into the fluid reservoir when in a sample mode.

A method for detecting a presence of a particle in a fluid is disclosed. The method includes the steps of directing a beam of electromagnetic radiation into the transient fluid; providing a sensor to detect an intensity of the radiation after passing through at least a portion of the fluid; generating a data representing the intensity detected by the sensor; and analyzing the data based upon a statistical analysis to detect the presence of a particle in the fluid and determine whether the particle is water or a solid particle.

A passive device to neutralize electrostatic charging of fuel when it exists a filter monitor cartridge is described. Filter cartridges containing light filter media generate electrostatic charges, which flow with the fuel as it exists the filter. The device neutralizes the charges as the charges fuel exits the filter/monitor using corona discharge.

Apparatus for removing water from a dielectric oil includes first and second spaced-apart electrically conductive walls, a bed of molecular sieves between the first and second walls, and a device for measuring the capacitance across the bed of molecular sieves between the first and second walls.

Apparatus for drying dielectric oil

A method and apparatus for determining the presence of surfactants in a liquid, such as a jet fuel or diesel fuel, by using the capillary rise technique, wherein an enclosed evacuated space is provided which is partially filled with water. A capillary tube is provided in the enclosed evacuated space having one of its ends submerged in the water. The liquid whose interfacial tension is to be measured is introduced into the evacuated space and the amount of rise in the capillary tube is measured. From the amount of rise in the capillary tube, the interfacial tension can be calculated. A high interfacial tension generally indicates the absence of surfactants which can affect the operation of coalescing filters which are designed to remove water from jet or diesel fuel before use.
