Flow limiter
Flow control device
A flow limiter or flow restrictor is a device to restrict the flow of a fluid, in general a gas or a liquid.[1] Some designs use single stage or multi-stage orifice plates to handle high and low flow rates. Flow limiters are often used in manufacturing plants as well as households. Safety is usually the main purpose of using a flow limiter. An example is manufacturing facilities and laboratories using flow limiters to prevent injury or death from noxious gases that are in use.[2] The flow limiter prevents gases from causing injury or death by reducing its cross-sectional area where gas flows.
