ABSTRACT:
An economical, accurate and efficient constant rate flow control operable at low pressure, high flow rates and high temperature comprises a tubular conduit fitting having a flow restrictor therein with a metering pin means movably mounted adjacent to the restrictor by means such as a coil spring so that movement of the pin means relative to the restrictor will vary the flow through the restrictor. As fluid flows past the pin means a pressure drop is created thereacross in proportion to the flow and the pin means is moved in response to the pressure drop whereby as the flow tends to vary, the pressure drop tends to vary proportionately and thereby maintain a relatively constant flow through the control. The restrictor is removable and by merely replacing it with one of another size the flow capacity may be varied.
