Abstract: A fluid heating system for heating a production fluid using a thermal transfer fluid, the production fluid being contained in a vessel includes an electric blower configured to receive ambient air and electrical input power and to provide output source air, a combustion system configured to receive the source air from the electric blower and to receive fuel and to provide the thermal transfer fluid, a heat exchanger configured to receive the thermal transfer fluid from the combustion system and configured to provide heat exchange from the thermal transfer fluid to the production fluid, and to provide output exhaust gas, and wherein the electric fan provides a predetermined volume flow rate of the output source air at a predetermined blower efficiency such that the fluid heating system has a Bulk Heat Flux of at least about 14.7 kBTU/Hr/ft2 and a Pressure Drop of at least about 0.7 psi.

Abstract: Systems and methods for calibrating an instrument having a tool and a work surface. An exemplary instrument may comprise a support member including a conductive surface. The instrument also may comprise a fluid-transport device including a conductive tube having an open end. A drive mechanism of the instrument may include a motor operable to drive movement of the surface and the tube relative to one another along an axis and into contact with one another. A circuit of the instrument may include a voltage source and the tube. A control module may be configured to calibrate a relationship between the drive mechanism and a position of the tube and/or surface along the axis based on a sensed change in an electrical property of the circuit that occurs when the tube and the surface contact one another.

Abstract: An LED excitation source and module useful for full plate imaging fluorescence instruments as well as methods for calibrating such instruments.
