Latest Patents

One of Jiang's latest patents is for a MEMS utility meter with an exchangeable metrology unit. This innovative all-electronic utility gas meter utilizes micromachined silicon sensors to measure gas metrology data for custody transfer or tariff in city gas metering applications. The design features two separate metrology units, one located in the main flow channel and the other configured as a bypass unit assembly. This allows for independent metrology tasks and onsite exchange during service, maintenance, or repair without dismantling the meter from the service pipeline. The bypass unit also performs self-diagnosis and data authentication, enhancing the meter's performance during field service.

Another notable patent is for a high accuracy battery-operated MEMS mass flow meter. This invention addresses the increasing demands for data communication and remote control in industrial processes. The MEMS mass flow meter is cost-compatible with conventional variable area flow meters while providing all-digital data processing, including accumulated flow rate measurements and user-programmable flow rate alarms. It is designed for pipe diameters ranging from 4 mm to 100 mm and can function as a stand-alone hand-held option, equipped with an industrial standard RS485 Modbus communication interface for easy network management.
