摘要： A proportional fluid control valve with improved linearity and reduced hysteresis is disclosed. The valve allows for smooth, gentle flow of fluid in a substantially linear fashion, with minimal turns. Preferably the valve is pneumatically actuated. Where temperature is not an issue, the valve can be actuated by any suitable means, including stepper motors, linear motors, voice coils or other force actuators. A versatile molded valve body that requires fewer parts compared to a machined valve is disclosed. In one embodiment, the molded valve body is designed specifically for flow control and contains two sensor housings with carefully positioned flow paths to optimize the use of space. The sensor housing or housings can be separately formed as inserts, allowing installation in various orientations.

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 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.
