In this paper, a temperature compensating system(TCS) for LPG dispenser has been developed. A TCS includes a processor(80C196) with an AID converter. I/O port(82C55) and 6-digit vacuum fluorescent display. Based on encoding signals from the gas flow meter, different calibration values from each apparatus and temperature compensating values from the temperature sensor, the TCS controls the LPG dispensing quantity with switching on or off the solenoid valves. The temperature compensation is performed with analog-to-digital conversion of the temperature sensor. The resolution of temperature compensation is nearly $0.5^{\circ}C$ using 10-bit ADC. The field test of the TCS shows the exact temperature compensation.

In this paper, a POS interfacing and temperature compensable LPG dispensing control system(LDCS) has been developed. A LDCS includes a 16-bit 80C196 microprocessor, RAM, ROM, video driver, and programmable peripheral devices. Based on gas flow encoding pulse, temperature-voltage conversion values and apparatus calibration values, the LDCS controls the LPG dispensing quantity with switching on or off the solenoid valves. The temperature compensation is performed with a 10-bit A/D conversion and its range is from +7$0^{\circ}C$ to -3$0^{\circ}C$ with a 0.5$^{\circ}C$ resolution.

The purpose of this study is safety evaluation of solar energy generation which is installed on the canopy at the LPG filling station. in case of a gas station, the solar energy generation was become legalization through a related law reform in 2008. Also, in case of a LPG filling station, the solar energy generation was become legalization through a related law reform in 2015. So, the related law that KGS CODE and Safety control of dangerous substances law and the case of installed solar energy generation in gas, LPG filling station was investigated. two scenarios are supposed for the CFD. Release of safety valve pipeline and ruptured dispenser leakage are the scenarios. The FLACS which developed GexCon in Norway was used for simulation. LPG dispersion to the upper side of canopy was very small with safety distance.
