Siargo's proprietary MEMS/NEMS sensors and system products can be used in energy (natural gas metrology, fuel cell fuel control etc), medical equipments, industrial gas metrology and control, and many others. Our current products offer World leading low power MEMS flow sensor and flow meters (including in-line and insertion type) featuring large turn-down ratio, high accuracy and easy to use. World first battery operated thermal mass flow meters that can be configured into two wire system while maintaining large turn-down ration with high accuracy Concentration sensors used for gas or liquid with dynamic flow rate measurement capability at the same time. The sensors feature fast response (<100 msec), low power and long life time. Specially design medical sensors provide sterilization capabilities. The bi-direction and auto- switch of dynamic ranges are also unique and easy to use for the applications
