SXS Flow Totalizer is a unit instrument of S series. Instrument accepts flow differential pressure signal, flow linear signal of flow transmitter and pressure, temperature compensation signal of accurate measurement. After sampling and processing, it compensates fluid density. The setting up value and flow Cumulative value will automatically maintain if power off. SXS Flow Totalizer can be widely used in metallurgy, petrochemical, power, light industry and other industrial process control systems, metering management system and energy-saving system.
