Pressurized gas e.g. methane, cylinder filling method for filling e.g. bus, involves parametrizing filling using chosen inlet pressure derivative value in cylinder based on time, where value is chosen according to environmental temperature

摘要

The method involves parametrizing the filling using a chosen derivative value of inlet pressure in a cylinder according to time. The value is chosen automatically or manually according to environmental temperature measured before the filling and the initial pressure of gas in the cylinder. The final pressure in the cylinder is calculated according to nominal filling capacity or calculated temperature.
