Instrumentation instrumentation is used for the detection, measurement, observation, calculation of a variety of physical, material composition, physical parameters, such as appliances or equipment. Vacuum leak detectors, pressure gauge, length measurement, microscopes, etc. belong to the multiplier instruments. Broadly speaking, instruments may also have automatic control, alarm, signaling and data processing functions, such as for industrial process automation in the pneumatic control instruments, and electric control instrumentation, and Distributed control systems are part of the instrument instruments. Instruments to improve, extend or supplement the human senses. People with sensory organs to vision, hearing, taste, touch external things, and microscopes, telescopes, sound level meter, pH meter, temperature gauge, vacuum centrifugal concentrator and other instruments, people can improve and expand these functional; In addition, some instruments such as magnetometers, radiation, etc. can be counted counts measured people's feelings and sense organs can not feel physical quantities, and some instruments can exceed the person's ability to record, calculate and count, such as high-speed cameras, computers and so on. Hydraulic filling sub-stations: CNG sub CNG filling station trailer arrives sub-station after gas station designed by high-pressure quick connector inlet hose, high pressure hydraulic hose back control gas tubes, CNG high pressure hydraulic hose outlet sub-station pry body connection. After connecting the hydraulic system starts to pry the body or sub-station in the PLC control system to monitor the gas station formalities hydraulic system pressure is low, the high-pressure pump to work, PLC automatic control system will open the inlet valve and outlet valve of a cylinder of Henan Construction gas station company, the high-pressure injection of a liquid medium cylinders, CNG sub-stations to ensure the trailer within the cylinder gas pressure is maintained at 20-22Mpa, CNG cylinders through the outlet after outlet CNG high pressure hose into the sub-station pry body buffer tank, high pressure piped to CNG filling machine for filling CNG fuel vehicles.
