A charge station is provided for filling a gas cylinder with gas. The charge station includes a gas output port configured to be fluidly connected to a supply of gas. The gas output port is configured to be fluidly connected to the gas cylinder for filling the gas cylinder with gas from the supply of gas. The charge station also includes a control system operatively connected to the gas output such that the control system is configured to control filling of the gas cylinder, and a radio frequency identification (RFID) reader operatively connected to the control system, the RFID reader configured to read data from an RFID tag on the gas cylinder.
摘要:
A dispenser apparatus that includes a first cascade stage having a first connector configured to connect to and disconnect from a first gas storage vessel, and a first conduit connected to the first connector and having a first valve and a first pressure measuring device, and a second cascade stage having a second connector configured to connect to and disconnect from a second gas storage vessel, and a second conduit connected to the second connector and having a second valve and a second pressure measuring device. A common flow path is fluidly connected to the conduits, and has a dispensing nozzle to connect to a vehicle during refueling. A controller is provided to control the first and/or second valve(s) to perform refueling using gas stored in at least one of the first and second gas storage vessels based on pressure measurements of the first and/or second pressure measuring device(s).
摘要:
A tank-in-tank fill level indicator, making use of noninvasive tank-in-tank measuring techniques. A vibration device, such as an exciter or resonator, vibrates the outer tank at its natural frequency of vibration, thereby inducing the vibration of the inner tank and a beating effect as a result of the interaction of the vibrations of the two tanks. A vibration detection device, such as an accelerometer, detects the resultant beating effect of the two tanks' induced vibrations. A data processing device, such as a microcontroller, processes the detection data to obtain the liquid volume. A display, wired or wireless data transmission device, or combination thereof, is then used to provide tank or container fill-level information.
摘要:
A method of documenting installation of a fluid handling device in a fluid flow system using a form and an identification device. The identification device has a first portion with first identification information and a second portion with second identification information. The method comprises installing the fluid handling device in the fluid flow system. The method further comprises checking for leaks associated with the fluid handling device installed in the fluid flow system. The second portion of the identification device is separated from the fluid handling device while the first portion of the identification device remains coupled to the fluid handling device after checking for leaks. The second portion of the identification device is then affixed to the form.
摘要:
A measuring system for the charged amounts in a pressure container using pressure and volume comprising: an information acquisition device that can collect information on volume and maximum charging pressure of the pressure container; first and second automatic valves, a reference container, a pressure sensor and a temperature sensor that are connected to a gas line between a storage tank and a charging nozzle; a control part that calculates the charged amounts through engineering calculations with pressure detected by the pressure sensor, temperature detected by the temperature sensor, and basic information on the pressure container and that calculates changes in temperature and volume of the pressure container to calibrate for the charged amounts, determine safety of the pressure container, and convert the calibrated charged amount to a sum of money; and a display part that receives the calculated information from the control part and inform it to a user.
摘要:
Recovery of dehydrogenation product must be done separately from supply of hydrogen fuel. However, there is a problem that it takes much time when dehydrogenation product recovery and fuel filling are done separately. A fuel filling/waste solution recovery apparatus includes measuring means to measure a volume of supplied fuel and a volume of recovered waste solution by measuring flow rates of solutions passing through a fuel filling nozzle and a recovery nozzle or piping, and a display which shows the volume of supplied fuel and the volume of recovered waste solution which are measured by the measuring means.
摘要:
Embodiments of the present invention generally provide methods and systems for managing gas cylinders by using radio-frequency identification (RFID) technology. In one embodiment, each gas cylinder includes a RFID transponder configured to transmit a RFID signal. The RFID signal may include an identifier for the gas cylinder, as well as data such as gas pressure, temperature, flow rate, battery level, etc. The RFID signals are received by RFID receivers, and are transmitted to a server (e.g., via a computer network). In one embodiment, the gas cylinder data received by the server is collected in a database, and thereafter used by a gas cylinder management software application. The gas cylinder management application performs tasks including selectively generating alarms, locating specific gas cylinders, and replenishment of gas supplies.
