Abstract

A testing apparatus and method for testing compressed gas dispensing stations are provided, wherein a back pressure regulator is used to imitate filling of receiving vessels without the need for receiving vessels. A mass flow sensor measures the mass of compressed gas dispensed to the testing apparatus, and a controller calculates the pressure for the back pressure regulator to imitate filling ofa receiving vessel.

Description

Background technique [0001] Compressed gas distribution stations are being developed for filling hydrogen-powered vehicles and CNG-powered vehicles. The design of compressed gas distribution stations can vary from manufacturer to manufacturer. [0002] The industry hopes to test hydrogen distribution stations and compressed natural gas (CNG) dispatch stations. [0003] The industry hopes to test compressed gas distribution stations under different conditions. Some conditions required for current testing may not be practical. For example, an industry may wish to test a situation where hydrogen or CNG distribution stations are used to distribute hydrogen or CNG to multiple vehicles in rapid succession, but a large number of vehicles are not available. The industry may wish to test various prescribed initial pressures of hydrogen or CNG distribution stations in the receiving container, where the receiving container does not have the prescribed initial pressure. Industry may wish to...
