© 2021 Siargo Product Datasheet MEMS Mass Flow Meters IoT and control valve ready MF5700 series mass flow meters are designed for general purpose flow metering and control applications enabled by IoT or wireless data while having the mobile power option. With Siargo's proprietary MEMS mass flow sensing technology and smart electronic circuitry, the products offer unprecedented cost-effectiveness with performance. The sensors directly measure mass flow with a very low pressure loss, opt with various wireless transmissions, and control ON/OFF valve. The current models can be readily applied to many process applications. MF5700 can measure a flow up to 200 SLPM. The mechanical connectors can be fully customized. Siargo Ltd.
