摘要： A flow sensor includes a main flow body, a laminar flow element, and first and second bypass channels. The first bypass channel is formed in, and extends at least partially around, the outer surface of the laminar flow element, and is in fluid communication with the main flow channel and defines a first bypass flow passage between the laminar flow element and the main flow body. The second bypass channel is formed in, and extends at least partially around, the outer surface of the laminar flow element, and is in fluid communication with the main flow channel and defines a second bypass flow passage between the laminar flow element and the main flow body.

摘要： Flow sensor assemblies having increased flow range capabilities are disclosed. In one illustrative embodiment, a flow sensor assembly includes a housing with an inlet flow port, an outlet flow port, a fluid channel extending between the inlet flow port and the outlet flow port, and a bypass channel having a pair of taps fluidly connected to the fluid channel at separate locations. A flow sensor for sensing a measure related to a flow rate of a fluid flowing through the fluid channel can positioned in the bypass channel. A pressure differential between the two taps of the bypass channel can drive a fraction of a fluid flowing through the fluid channel through the bypass channel. The flow sensor assembly may be configured to achieve, control, and/or balance a desired fraction of fluid flow through the bypass channel and past the flow sensor.

摘要： A thermal liquid flow sensor and method of forming same. The sensor has a substrate and one or more sensing elements, disposed on the substrate, for sensing a property of a liquid. The liquid flow sensor, which can be for example a microsensor having a microbrick® structure, has a hydrophilic layer which is disposed on the substrate and covers the sensing element(s). The hydrophilic layer is preferably formed from a spin on glass material, such as for example a silicate or phosphosilicate. A silicon nitride layer can be disposed on the sensing element(s) and interpose the substrate and the hydrophilic layer. The silicon nitride layer can be oxidized, for example, by means of plasma oxidation or oxygen ion implantation so to form the hydrophilic layer thereon. A variety of other hydrophilic compounds can be utilized to form the hydrophilic layer such as, gold, palladium and diamond like carbon.

摘要： A system and method for heating a fluid include a base and a cover, and a flexible heating element maintained between the base and the cover. A wall plate can be provided to which the flexible heating element is connected to create a sealed fluidic flow path encased between the base and the cover, which provides a geometry that creates at least one air pocket for thermal isolation. A fluid can then flow through the fluidic flow path in order to be heated by the flexible heating element, thereby permitting the fluid to be heated to a desired temperature within a particular timeframe. The flexible heater can be formed from, for example, copper. The fluid is mixed in the fluidic flow path to ensure a uniform temperature of the liquid at an exit of the fluidic flow path.

摘要： Sensor systems and methods are disclosed herein. A relative humidity sensor is generally associated one or more porous heating elements. A porous resistive material surrounds the relative humidity sensor. Additionally, one or more flat heating elements can be bonded to a base of the relative humidity sensor to conduct heat and insure uniform heating about the relative humidity sensor. The porous heating elements can be configured to permit humid air to pass through the porous heating elements. Also, the porous heating element(s) can be assembled slightly offset from a surface of the relative humidity sensor so that air that is saturated with water vapor passes through and is heated by the porous heating element in order to evaporate water droplets associated with the water vapor and thereby reduce relative humidity to a measurable level. The porous resistive material can be configured from a material such as, for example, tantalum or nichrome. The porous resistive material can also be configured in a sheet arranged in a woven pattern.

摘要： A high mass flow sensor device having a flow restrictor formed by a body having a generally cylindrical shape with an upstream end and a downstream end separated by a center portion having pressure taps proximate the junction of the ends with the center portion. Flow passes from upstream to downstream. The upstream end has a decreasing tapering inner surface for contact with the flow and the downstream end having an increasing tapering inner surface for contact with the flow. A center portion has radial and axial restrictor elements positioned forming axial openings in the path of flow through the center portion. The restrictor elements having tapered leading edges. One opening is formed by a central tube having a predetermined diameter and the remaining openings are radially extending members supporting the central tube, each of the radially extending members having substantially the same cross-sectional area as the central tube.
