During dispensing natural gas from natural gas dispenser to NGV car storage tank, mass, pressure and temperature of the natural gas inside the tank are increase. Based on Ideal Gas Law, as mass is inversely proportional to temperature, the value of temperature should be as low as possible to get the maximum value of mass of natural gas dispensed to the tank. Thus, a temperature control system is invented using instrumentation equipments available in Natural Gas Test Rig and Industrial Automation Instrumentation Laboratory and simulated using LabView Data Acquisition software- A cooling mechanism represented by a fan and a heating mechanism represented by a light bulb are assembled in order to provide a specific range of temperature of the tank; if the temperature exceeded the highest limit a cooling system will starts and if the temperature goes below the lowest limit, a heating system will starts. While thetemperature is within the range, a PID controller will control the temperature of the tank to a certainvalue that will maximize the mass dispenses into the tank.
