| 20080221822 | System and Method for Calibration of a Flow Device - Embodiments of the present invention provide a system and method for rapid calibration of a flow device. A flow device can be provided with a calibration flow curve (e.g., represented by an n | 09-11-2008 |
| 20090113985 | FLUID FLOW MEASURING AND PROPORTIONAL FLUID FLOW CONTROL DEVICE - Embodiments disclosed herein provide restrictive-flow flow measurement devices, valve improvements and signal control devices and processes that control the flow of liquids, including control processes for single-liquid calibration. In some embodiments, a fluid flow device can be calibrated using a single standard calibration fluid. The fluid flow of a first fluid through a flow meter is measured by calculating a first pressure difference between pressures sensed by two pressure sensors of the flow meter. The fluid flow of a second fluid through the flow meter is measured by calculating a second pressure difference between pressures sensed by the same two pressure sensors. A calibration coefficient is determined based upon the relationship between the flow rate, the fluid density and the calculated pressure difference for the first and second fluids. A relationship between the calibration coefficient and the kinematic viscosity of each fluid is then determined and stored. | 05-07-2009 |
| 20090116334 | METHOD FOR CONTROLLED MIXING OF FLUIDS VIA TEMPERATURE - Embodiments of the present invention provide a method for continuous flow production of mixed fluids. The mixed fluids can comprise a mixture of different fluids or a mixture of the same fluid having different input properties such as temperature. In general, two streams of fluid of varying temperature are supplied to a mixer. The flow rate of each of the input fluids can be regulated to produce a mixed fluid at a desired flow rate and temperature. As an example, mass flow controllers can regulate the flow rates of a hot and cold stream of de-ionized water to produce a stream of de-ionized water at a desired flow rate and temperature. | 05-07-2009 |
| 20100236643 | System and Method for Flow Monitoring and Control - One embodiment of the present invention can include a flow control device that comprises an inlet, an outlet in fluid communication with the inlet, a pressure sensor, which may or may not be the only pressure sensor of the fluid control device, and a controller coupled to the pressure sensor. The controller can be configured to generate a valve control signal based on a measured pressure at a single pressure sensor. | 09-23-2010 |
| 20110180148 | GASIFICATION SYSTEMS AND METHODS FOR MAKING BUBBLE FREE SOLUTIONS OF GAS IN LIQUID - Embodiments disclosed herein can introduce low amounts of gas in a liquid with fast response time and low variation in concentration. In one embodiment, a gas is directed into an inlet on a gas contacting side of a porous element of a contactor and a liquid is directed into an inlet on a liquid contacting side of the porous element of the contactor. The liquid contacting side and the gas contacting side are separated by the porous element and a housing. The gas is removed from an outlet on the gas contacting side of the porous element at a reduced pressure compared to the pressure of the gas flowing into the inlet of the contactor. A liquid containing a portion of the gas transferred into the liquid is removed from an outlet on the liquid contacting side of the porous element, producing a dilute bubble free solution. | 07-28-2011 |

| 20110204092 | CONNECTOR APPARATUS AND SYSTEM INCLUDING CONNECTOR APPARATUS - A connector apparatus is provided which is configured to replace a separation module in a system for dispensing a fluid. When it is desired to purge the system of a dispensed fluid, the connector apparatus, having the same configuration of an inlet and an outlet as the separation module, replaces the separation module and a purging fluid is passed through the system. | 08-25-2011 |
