摘要： Methods and systems for preventing degradation of a sensor exposed to a harsh fluid, such as one that might corrode or be exposed to radioactive contaminants, live pathogens, freezing temperatures, overheating, particle deposition or condensable vapors is disclosed. An auxiliary purge stream of comparatively clean fluid or purge fluid is utilized, which flows past the sensor in opposition to the harsh fluid, thereby preventing the harsh fluid from contacting and degrading the sensor. The clean fluid itself may comprise a purge gas, such as clean, dry air, or a liquid that is compatible with the composition of the harsh fluid. The flow and pressure of the clean fluid can be adjusted utilizing one or more supply regulator valves.

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： The present disclosure relates generally to flow sensors, and more particularly, to methods and devices for reducing variations in fluid flow across the flow sensor for increased accuracy and/or reliability. In one illustrative embodiment, a flow sensor assembly includes a housing with an inlet flow port and an outlet flow port. The housing defines a fluid channel extending between the inlet flow port and the outlet flow port, with a flow sensor positioned in the housing and exposed to the fluid channel. The flow sensor is configured to sense a measure related to the flow rate of a fluid flowing through the fluid channel. A porous insert is situated in the fluid channel, sometimes upstream of the flow sensor. When so configured, and during operation of the flow sensor assembly, a fluid may pass through the inlet flow port, through the porous insert, across the flow sensor, and through the outlet flow port. The porous insert may include pores that are configured to reduce the turbulence in the fluid passing the flow sensor.

摘要： A high mass-flow sensing apparatus and method of forming the same, comprising a flow tube bypassed in a flow path defined by a flow channel, through which a fluid flows. A flow sensor can be disposed in the flow tube for measuring a flow rate of the fluid in the flow channel. A set of narrow rectangular flow restrictors can be molded into the flow tube and adjacent to the flow sensor. Each flow restrictor can include several rectangular cutouts that are molded into upstream and/or downstream portions of the flow tube in order to limit the flow rate of the fluid across the flow sensor. The flow restrictors can laminarize the flow rate of the fluid in the flow tube and thereby reduce flow turbulence and lead to optimal sensing performance of the flow sensor.
