FV Automatic Flow Controller – Overview Accurate flow control is vital to a wide variety of processes, for example blending and dosing applications. This controller automatically regulates the flow of liquids or gases by using available line pressure. Once set to the required value, flow is maintained accurately independently of supply pressure fluctuations or varying back pressure downstream, subject to certain minimum overall head loss requirements. No electrical power or external flow measurement input is required. By keeping the required fluid delivery rate constant, one can ensure consistent product quality irrespective of process liquid head changes throughout a batch. These controllers are used in flow control systems such as aircraft fuel delivery systems, to prevent the hazard of excessive flows and protect metering systems from over-speeding. On natural gas or fuel oil delivery systems to multiple burners, the units can maintain optimum flow rate to each burner independently. Available in sizes from 15mm to 100mm. All units can be fitted with a flow scale plate calibrated for process conditions. Once set to a flow rate, the Flostat maintains that flow independent of line pressure fluctuations, FV Automatic Flow Controller – Features Suitable for hazardous liquids or gases Fast response Fully automatic flow control No power required 1/2” – 4” line sizes 10:1 control range
