摘要： Apparatus and a control system for monitoring (preferably digitally) and/or controlling pressure to a pneumatic load such as a proportional fluid control valve and using a measurement input from a fluid measurement device that responds to a flow rate, the liquid measurement input being used to control the pressure to the pneumatic load so that pneumatic load may be increased or decreased (to proportionally open or close the pneumatic valve) to change the flow rate of the fluid to a desired rate. The pneumatic load can also be adjusted (to proportionally open or close the pneumatic valve) to accommodate changes in temperature and viscosity of a fluid.

摘要： Embodiments of the present invention provide I/O systems, methods, and devices for interfacing pump controller(s) with control device(s) which may have different interfaces and/or signaling formats. In one embodiment, an I/O interface module comprises a processor, a memory, and at least two data communications interfaces for communicating with a pumping controller and a control device. The I/O interface module can receive discrete signals from the control device, interpret them accordingly and send the packets to the pump controller. The pump controller reads the packets and takes appropriate actions at the pump. The I/O interface module can interpret packets of data received from the pump controller and assert corresponding discrete signals to the control device. The I/O interface module is customizable and allows a variety of interfaces and control schemes to be implemented with a particular multiple stage pump without changing the hardware of the pump.

摘要： Embodiments of the 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.

摘要： Systems and methods for reducing temperature variations induced by fluid handling equipment in process fluids by separating heat-producing portions of the control equipment from portions of the equipment which handle or are in close proximity to a fluid flow path. In one embodiment, the fluid handling components are contained in a first enclosure, while the heat-generating components are contained in a second enclosure. An air gap is maintained between the two enclosures to provide thermal isolation of the fluid handling components from the heat-generating components. In one embodiment, the air gap is maintained by connecting the two enclosures using insulating spacers. Interconnects between components in the two enclosures may be routed through an insulating tube that is sealed at each end to prevent heat transfer through the tube.

摘要： A control system for digitally monitoring and/or controlling pressure to a pneumatic load such as a stop/suckback valve. Pressure is sensed in the pneumatic fluid input lines to the pneumatic load, and a closed loop control is used to maintain the pressure at a predetermined level. In an alternative embodiment, the control system is used to ensure equal dispensing in multi-point dispense apparatus. Thus, pressure is sensed downstream of each valve in fluid communication with a respective nozzle. Any pressure differential detected is corrected by appropriate valve adjustment.

摘要： A method and apparatus for controlling a low volume, low rate precision dispensing pump for photochemicals and the like comprises generating constant current signals having magnitudes related by sin and cos values to the angular step size of the stepper motor pump, and varying the magnitudes smoothly over an incremental range of angles to vary the quantity of liquid dispensed. The step size and step rate can be varied to provide a desired liquid dispense rate. The magnitude of the current applied to the motor is ramped up and down while maintaining constant the relative relationships in the magnitudes of the currents applied in order to smoothly step the motor over a desired step angle.

摘要： Systems and methods for compensating for pressure increase which may occur in various enclosed spaces of a pumping apparatus are disclosed. Embodiments of the present invention may compensate for pressure increases in chambers of a pumping apparatus by moving a pumping means of the pumping apparatus to adjust the volume of the chamber to compensate for a pressure increase in the chamber. More specifically, in one embodiment, to account for unwanted pressure increases to the fluid in a dispense chamber the dispense motor may be reversed to back out piston to compensate for any pressure increase in the dispense chamber.
