Abstract

The design and structure of a regulated digital gas dispense apparatus is exhibited in this disclosure. The MEMS mass flow meter embedded with a Bluetooth communication device and powered by a battery pack is designed to replace the mechanical low pressure gauge in a conventional gas dispense regulator such that the dispensed gas flowrate as well as totalized dispensed gas volume in each session or in consequent sessions can be continuously and precisely registered. The measured data are further relayed to local users via the local display or physical data port as well as via a paired smart device running a customized APP that can further relay the data to a designated cloud for cloud data processing, and the data can be streamed reversely. This disclosure shall assist and realize the ultimate optimized management for the users, distributors and/or gas manufacturers in the gas dispensing industry.
