Abstract
With increasing demands on data communication and remote control in current industrial processes or gas measurement applications, development of new technologies would be necessary. The current invention presents a MEMS mass flow meter that are cost compatible with conventional variable area flow meters while providing all digital data process including accumulated flow rate measurements, user programmable flow rate alarm and flow data storage. These in-line meters provide packages in pipe diameter from 4 mm up to 100 mm. It is powered with battery and can be used as a stand-alone hand-held option. The meter is also equipped with the industrial standard RS485 Modbus communication interface for easy network and remote management.
