This present invention for an in-line fluid heater suitable for heating ultrapure fluids utilizes a radiant energy source that generates infrared radiation to heat a fluid. The fluid to be heated is passed through a vessel such as a tube. The vessel, formed of PFA or polytetraflouroethylene, is coiled around the lamp or lamps. A chamber surrounds the lamp or lamps and the vessel. A temperature sensor at the outlet end of the vessel sends a signal to a controller that adjusts either the flow of fluid through the vessel or the intensity of the lamp or lamps, thereby controlling the fluid temperature at the outlet. The system is useful in any application requiring an ultraclean, non-contact method of raising the temperature of various liquids and gases.

Method device for heating fluids

A device measures air flow at multiple points in an air channel. The device includes a metering plate that has multiple passages through the metering plate. The metering plate is adapted to be positioned across the air channel in an orientation that places two or more of the multiple passages at two or more respective locations within the air channel. The metering plate is also adapted to receive two or more flow meters at the two or more passages, respectively. In addition, the metering plate is configured so that respective air flow velocities at the two or more locations when the metering plate is positioned across the air channel substantially matches air flow velocities at the two or more locations when the metering plate is not positioned across the air channel. An example embodiment includes holders such as sockets that keep the flow meters fixed in the metering plate with regard to pitch and roll.
