Provided is a system for stabilizing a flow of gas introduced into a sensor, wherein, in connection with manufacturing equipment comprising a process chamber, a process chamber vacuum pump installed to remove internal gas of the process chamber, and a sensor device configured to be able to receive the internal gas of the process chamber through a sensor connecting pipe and to detect components thereof, the system comprises a sensor connecting pipe and a bypass pipe branching off from the sensor connecting pipe such that a part of the gas can be directly discharged to the outside without being introduced into the sensor, and the system is accordingly configured to stably provide the sensor device with a part of the internal gas within a predetermined range per time, regardless of a change in the pressure state of the process chamber.

A method for regulating a volume flow rate, and a test stand with a liquid circuit for carrying out the method is provided. A pump and a flow control valve are connected in series in the liquid circuit, and the orifice width of the flow control valve is set as a function of a setpoint value of the volume flow rate of the liquid, in order to specify, on the basis of the orifice width, a characteristic curve of the pump that plots the volume flow rate over the differential pressure. Once a characteristic curve has been specified, the differential pressure of the pump is set such that the volume flow rate corresponds to the setpoint value of the volume flow rate.

A system for precision liquid delivery includes a gas reservoir having a known volume. The system has a tightly load-coupled pneumatic driver (a “TLCP driver”) that is configured to receive input power to cause the TLCP driver to move gas into the gas reservoir to produce a gas drive pressure. A valve is configured to couple the gas reservoir with a fluid reservoir having an unknown volume. The valve is further configured to selectively isolate or pneumatically couple pressures in the gas reservoir and the fluid reservoir. A gas-fluid interface couples pressure in the fluid reservoir to pressure in a fluid path. The fluid path is configured so that the fluid drive pressure driving the liquid in the fluid path is substantially the same as the fluid reservoir pressure. The system also has a pressure sensor configured to detect pressure in the gas reservoir and/or the fluid reservoir.

A well management system provides Internet-enabled monitoring, configuration, and control of a well system that may include a pump and a pressure tank. A controller is operatively coupled to the pump. The controller controls the pump based on pressure readings from a pressure sensor to maintain a configured pressure range within the system. The controller can communicate with a management system via a communications network. The management system is further in communication with one or more client devices, which may be associated with a homeowner, a service provider, a manufacturer, or the like. Via the management system, the client devices can receive information from the controller and send commands to the controller.

A smart electronic power steering system and method for a retrofitted electric vehicle are provided. In one embodiment, an electronic power steering system comprises a relief valve; a pump in communication with the relief valve; a motor configured to operate the pump; a motor controller configured to control the motor; and a processor.
