Also known as differential pressure regulator, our offered Model 2203 Flow Controller is known to keeps mass flows at a constant rate under a given constant level of supply pressure. This has an ability to load pressure fluctuations. This flow controller consists of needle valve, which protects flows from being affected by secondary or outlet pressure fluctuations. This controller controls the rate of flow to the given set point. Model 2203 Flow Controller is particularly designed to control minute gas flows with accuracy and keep a certain constant flow rate.
