摘要： A remote pond volume adjustment system includes a control circuit, a weather receiver configured to receive a public broadcast from the National Weather Service, and a weather receiver decoder connected with the weather receiver and the control circuit that is configured to digitize the public broadcast and output a digital weather code. A cellular network communication device connected with the control circuit is configured to communicate with a property manager/owner. The control circuit is programmed to selectively open and close a drain valve based on at least one of a communication from the property manager and the digital weather code.

摘要： A valve includes a valve body, an inlet in the valve body in fluid communication with the gas and an outlet in the valve body, and a rupture disc in fluid communication with and between the inlet and the outlet that prevents fluid communication between the inlet and the outlet. The valve also includes a piston that is urged by a gas from the gas source to rupture the rupture disc to allow fluid communication between the gas source and the outlet.

摘要： A fueling dispensing display system with an electronic display located at a position that is visible and convenient to a vehicle driver for monitoring fueling operation pertaining fuel dispensing. The system receives and displays information concerning fuel dispensing that allows a driver of a vehicle to visualize initialization cycle, product selection, price per unit of volume, fuel dispensing progress, and end of sale final values. The system automatically and continuously displays the information during the fueling operations and the end of sale values on located displays. Alternatively, the system can display the information on portable devices, remote terminals, or database structure in either physical or virtual environment.

摘要： A fluid network exchange system for efficiently exchanging fluid in a fluid network for prevention of hygiene risks. The system includes a source and a plurality of sinks. The system also includes flow meters for determining the flow rate at each of the sinks and automatic flushing devices for flushing fluid at each of the sinks. The system determines an order and a flushing time for the plurality of sinks to be flushed. The sinks are flushed starting with the sink with the highest flow rate and ending with the sink with the lowest flow rate. Flushing times are determined based on the length of different pathways corresponding to different sinks.

摘要： Systems and methods related to dispensing fluid and controlling a dispensing operation. The system includes a fluid dispenser including an inlet and an outlet, the dispenser being operable to start and stop the flow of the fluid from the outlet onto a substrate. The system also includes a fluid supply reservoir adapted to hold the fluid, and having an outlet coupled in fluid communication with the inlet of the fluid dispenser to establish a flow path for the fluid between the fluid supply reservoir and the outlet of the fluid dispenser. The fluid supply reservoir further includes a pneumatic input coupled to an air flow path adapted to receive pressurized air for forcing the fluid from the outlet of the reservoir. An electronic air flow meter device is operatively coupled to the air flow path to produce electrical output signals.

摘要： A mass flow control apparatus comprising a proportional valve upstream of a flow measurement portion, a pressure sensing element fluidly connected to determine a fluid pressure downstream of the flow measurement portion, and a dynamically adjustable variable valve downstream of the flow measurement portion and adjacent to the pressure sensing element connection. Fluid conductance of the variable valve is adjusted according to a control scheme based upon limitations of the flow measurement portion. Integral flow verification may be enabled with additional fluid pathway elements upstream of the flow measurement portion.

摘要： Fill stations and base stations are provided for personal pump systems. The fill stations may be opened and closed to accept a reservoir and to allow fluid to be introduced into the reservoir for use with personal pump systems. The fill stations may hold the reservoir at a tilt relative to an underlying surface and may discourage overfilling of the reservoir. The filling stations may also include viewing windows having fluid lines marked thereon for indicating volume of fluid within the reservoir.

摘要： An energy-reducing method and apparatus for retrofitting a single zone, constant volume HVAC system, with or without an economizer, that provides heating, cooling, and ventilation to occupants within a building space. The present invention includes the introduction of a programmable logic controller and variable frequency drive (VFD) that takes control of the existing fan, heating, cooling, and optional economizer operation. The reduction of the fan speed in the ventilation mode when the 100% operation is not needed saves significant energy of the existing constant volume HVAC system where the fan motor is designed to run 100% of the time.

摘要： A method of controlling a water reservoir supply pump arrangement determines a set value p, q, v, n of the pump arrangement based on an offset value pref, qref, nref, vref, G0 reduced by a component which is a function of a difference between an actual water level h and a predetermined water level href in a water reservoir. The difference is weighted by a proportional gain factor G. Further, a water reservoir supply pump arrangement is provided including at least one water pump and a control device for controlling the at least one pump.
