SRK-DL Series Co2 Mass Flow Controller: A Comprehensive Solution for Precise Gas Flow Measurement and Control

The SRK-DL Series Co2 mass flow controller is an advanced instrument designed to accurately measure and control the flow rate of CO2 gas at ultra-low rates, as low as 2 sccm (2 ml/min). This high-precision flow controller finds wide applications in various fields such as gas chromatography, gas analysis, laboratory research, and industrial processes where precise gas flow measurement and control are of utmost importance.
 

Working Principle of Co2 mass flow controller

The Co2 mass flow controller operates based on the principle of differential temperature calorimetry before and after capillary heat transfer. It consists of a low flow mass flow sensor and a laminar flow layering device. The sensor measures the mass flow of CO2 gas, independent of temperature and pressure, by utilizing the differential temperature created by the heat transfer. The flow signal measured by the sensor is then amplified and compared with the set voltage. The resulting difference is used to drive the control regulating valve, enabling closed-loop control of the gas flow through the channel, ensuring it matches the set flow rate.
