    摘要: 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.

    摘要: Embodiments of the present invention provide a system and 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.

    摘要: Fluid separation assembly that allows easy and fast change-out even in confined spaces, and also minimizes or eliminates leakage during change-out. A fluid separation unit having a housing containing separation means, the housing having an inlet and an outlet spaced from the inlet, each including a fitting for attachment of the housing to a manifold or other device allowing fluid communication through the separation means to a point of use is provided. The fittings are designed for quick connect/disconnect, and for minimal or no leakage. The fittings may be on opposite ends, with top and bottom fittings of different configurations, thereby ensuring proper installation of the assembly. The particular medium to be separated is not particularly limited, and can include slurries, fluids including water, and pre-loaded chromatography columns.

    摘要: One embodiment of the present invention can include a flow control device comprising an inlet, an outlet, a pressure loss element between the inlet and outlet, a pressure sensor located upstream from the constriction configured to measure a first pressure of a fluid flowing through the flow control device, a pressure sensor located downstream from the constriction, configured to measure a second pressure of the fluid flowing through the flow control device; and a controller coupled to the first pressure sensor and the second pressure sensor to generate a valve drive signal. The controller can generate a valve control signal based on a differential between the first pressure and the second pressure during a first mode of operation. The controller can also generate a valve control signal based on a measured pressure at a particular pressure sensor during a second mode of operation. The mode of operation can automatically switch.

    摘要: Embodiments disclosed herein provide a pump or a multiple-pump system that can mix chemicals without dilution tanks and can dispense the mixture of chemicals in a precise and highly controllable manner, particularly useful in semiconductor manufacturing processes. In some embodiments, one or more piston pumps of similar displacement are used to mix and dispense the chemical directly. A first valve is opened to a first chemical source. A piston is moved in a first direction to a selected position in a chamber to draw the first chemical into the chamber. The first valve is closed and a second valve is opened to a second chemical source. The piston is moved in the first direction to a second position in the chamber to draw in the second chemical and mix the chemicals. The second valve is closed and the piston is moved to dispense the fluids through a dispense port.
