摘要： A method of controlling the injection of hydraulic fluid into a high pressure diaphragm compressor having a hydraulic system, the method including: measuring a representation of pressure in a high-pressure part of the hydraulic system of the diaphragm compressor, and maintaining a desired pressure in the high-pressure part of the hydraulic system by adding hydraulic fluid to the high-pressure part of the hydraulic system under the control of a controller on the basis of the measuring of pressure.

摘要： A pressure sensor having a housing connected to a compressor head, the housing including a piston movably mounted in a cylinder, the cylinder is fluidly connected to a high-pressure part of a hydraulic system of the compressor, where the piston is adapted to be moved in a first direction away from the compressor head by the pressure of the hydraulic fluid in the high-pressure part, thereby moving a displacement member which is movably attached to the housing by one or more flexible suspensions, and the piston is adapted to be moved in a second direction towards the compressor head by the flexible suspension via the displacement member.

摘要： The invention related to a system for control of a hydrogen refueling station. The control of the hydrogen refueling station is optimized according to a high frequency tank profile in a time period between time A and time B. The high frequency tank profile includes selecting a first of the plurality of vessels as supply to the compressor during at least part of the refueling of the vehicle tank, the selection is based on pressure of hydrogen gas in one or more vessels of the supply storage. The control of the hydrogen refueling station is furthermore optimized according to a low frequency tank profile in a time period between time C and time D. The low frequency tank profile includes preparing one or more hydrogen refueling station components to enable a plurality of vehicle tank refuelings in the subsequent time period between time A and time B.
