摘要： A thermal flow-rate sensor includes: a first temperature sensor 20 that detects the temperature at a specified location of the outer-wall surface of a pipe; a heat-transfer element 50 that is arranged on the outer-wall surface of the pipe in a state separated from the first temperature sensor 20, and that exchanges heat with a measurement medium by heating or cooling the outer-wall surface of the pipe 10; a second temperature sensor 30 that detects the temperature of a portion of the outer-wall surface of the pipe 10 that is heated or cooled by the heat-transfer element 50; and a control unit 60 that performs specified processing. A heat-flux sensor 40 is arranged between the heat-transfer element 50 and the outer-wall surface of the pipe 10 and directly detects heat flux between the heat-transfer element 50 and the pipe 10; and the control unit 60 detects the flow rate of the measurement medium based on the temperature that is directly detected by the first temperature sensor 20, the temperature that is detected by the second temperature sensor 30, and the heat flux that is detected by the heat-flux sensor 40.

摘要： A flip-chip flow sensor has electrical components, such as temperature sensors and a heater, on the top of a substrate and has a channel formed in the bottom of the substrate. The channel is separated from the substrate's top by a membrane of substrate material. A fluid flowing through the channel is separated from a heater, upstream temperature sensor, downstream temperature sensor, bond pads, and wire bonds by the membrane. Heat flows through the membrane easily because the membrane is thin. As such, the electrical elements of the flow sensor, the bond pads and the wires are physically separated from a fluid flowing through the channel but can function properly because they are not thermally isolated.

摘要： The invention provides a probe for a flowmeter which can be employed in various flow measuring devices utilizing semiconductor or ceramic thermistors. The invention comprises an apparatus for determining the fluid flow rate of a liquid passing through a conduit made of a material having a low thermal conductivity, comprising a probe disposed at least partially inside the wall of the conduit, part of the probe being substantially aligned with an inner surface of the wall, the probe being operationally connected to a control and display unit. The probe comprising a printed circuit board (PCB) on which at least two thermistors are mounted; an upstream thermistor serving for baseline measurements and a spaced apart downstream self-heated thermistor. The control and display unit repeatedly measuring the electrical resistance of the thermistors to generate signals which are electronically processed by the control and display unit to indicate flow rates.

摘要： An intravenous infusion system that shows infusion flow rate, volume of medication infused, and alarming during malfunction. User intervention to adjust flow rates deviation is possible, using the data already stored in the system prior to the onset of making the adjustment. The system detects flow rate by measuring temperature dynamics in a section of the fluid path, unlike other systems that measures the electromechanical output of the pumping source if the counting of drops is not possible. This fundamental difference allows the invention to be used in any system that has a pumping source that provides a continuous fluid path as it measures actual flow of fluid in a segment of the fluid path, independent of pumping mechanism design.
