- Abstract:
- A thermal mass flow meter with micromachined sensing elements is designed and manufactured to address the accurate gas consumption, remote data and connectivity of gas cylinders in particular for medical, food and fuel supply industries. The designed flow meter has a rugged and compact enclosure whereas the flow dynamic range is over 100:1 with the mass flow totalizer capability. Verification of the metrology properties of this design was performed with a precise scale which weighted the gas consumption directly from the weight loss of the cylinder during usage, and compared to the totalized mass flow measured by the meter. The data transmission is realized via a Bluetooth and a smart device APP, or with a 3G/4G network or a NB-IoT or similar wireless network. For the grouped gas cylinders, the meter could also register each cylinder before usage or via a programmed consecutive register alert that can be timely sent to the end user. The data relayed to the cloud via the smart device/APP or a concentrator enable the gas cylinder user and suppliers to instantly access the cylinder status. The system enables the effective management of the gas cylinder manufacture, inventory and delivery. It also provides added value services to the end user who shall be timely notified for any programmed gas consumption.
