Patent number: 8365594Abstract: The invention provides an oil level or condition sensor featuring a housing and a baffle or plate arrangement arranged in the housing, where the baffle or plate arrangement forms a capacitor when the housing is filled with oil, the baffle or plate arrangement being responsive to a signal, for providing an oil level or condition sensor signal containing information about the level or condition of the oil in the housing. The baffle or plate arrangement may include one or more plates or a single or multiple star shaped baffles. The one or more plates or multiple star shaped baffles are spaced apart to form the capacitor. The level or condition of the oil within the baffle or plate arrangement changes the inductance. The single or multiple star shaped baffles each have a small hole in the center which provides a visual indication of the oil level. The housing has a transparent window. The inductance change can be measured and used to send alarms or warnings.Type: GrantFiled: September 27, 2010Date of Patent: February 5, 2013Assignee: ITT Manufacturing Enterprises, Inc.Inventors: Eugene P.

Patent number: 6591697Abstract: A method and system for determining fluid flow rates through a motor driven pump controlled by a variable speed drive is disclosed. The variable speed motor drive is used to characterize a pump fluid flow for a plurality of motor torque values at a plurality of known pump speeds. These characterized pump flow rate/torque values/speed are stored and used to determine a pump fluid flow at a measured pump speed and motor torque by interpolating between the known characterized fluid flow/torque/speed values. In another aspect of the invention, the pump flow rate at a measured torque, at a specified characterizing speed value is determined by interpolating between known characterizing pump flow rates. The determined pump flow rates can then be used to determine pump flow rates at a measured speed by interpolating between corresponding speed values which bound the measured speed.Type: GrantFiled: April 11, 2001Date of Patent: July 15, 2003Inventor: Oakley Henyan

Patent number: 6487903Abstract: A method and system for determining pump cavitation is disclosed. In accordance with the principle of the invention, changes in dynamic fluid pressure within a pump are monitored and compared to a determined cavitation alarm pressure. The determined cavitation pressure is determined as a known percentage of a known non-cavitation pressure. Fluid cavitation is determined when the change in dynamic fluid pressure falls below the determined cavitation alarm pressure. In a further aspect of the invention, a remaining mechanical seal operational life can be determined by maintaining a total time of fluid cavitation and reducing the expected life by the known operational time of the pump and the time the pump is in cavitation.Type: GrantFiled: April 24, 2001Date of Patent: December 3, 2002Assignee: ITT Manufacturing Enterprises, Inc.Inventors: Eugene P.
