摘要： Various embodiments are directed to a fluid composition sensor device and method of using the same. In various embodiments, the fluid flow composition sensor is configured to receive a volume of fluid, the fluid composition sensor comprising a housing, a removable fluid flow component, an impactor nozzle, a collection media assembly dock element configured to receive a replaceable collection media assembly comprising a collection media configured to receive one or more particles within the volume of fluid, an imaging device configured to capture an image of at least a portion of the one or more particles received by the fluid composition sensor, and a controller configured to determine, based at least in part on the image, at least one particle characteristic of the volume of fluid. The imaging device may be configured to capture the image of one or more particles received by the fluid composition sensor using lensless holography.

摘要： A flow sensing module is provided for determining a flow rate of a fluid flowing through a flow channel. The flow sensing module may include an integrated flow restrictor, sometimes including a plurality of concentric ribs defining a plurality of orifices shaped to match the curvature of the wall of the flow channel. A first sensing port may open into the flow channel upstream of the flow restrictor, and a second sensing port may open into the flow channel downstream of the flow restrictor. A flow rate of a fluid flowing through the flow channel may be determining using a differential pressure between the first and second ports created by the flow restrictor, either using a flow sensor or a pressure sensor. The particular arrangement and relative dimensions of the orifices of the flow restrictor and the pressure ports can result in substantially reduced noise.

摘要： A flow sensor assembly including a top flowtube that defines an inlet port, an outlet port, and a main channel. An inlet flow channel fluidly may connect the inlet port of the flow sensor assembly to the main channel. An outlet flow channel fluidly may connect the main channel to the outlet port. The bottom flowtube may include a shroud which acts as a cover over an electronic circuit board. The shroud may eliminate a step, created by the flow sensor, to provide a continuous flow path over the sensor. The channels may be formed to utilize the entire footprint of the flow sensor assembly.

摘要： A sensor housing includes an inlet flow port, an outlet flow port, a flow sensing region, and a flow channel extending between the inlet flow port, the flow sensing region and the outlet flow port. The flow channel defines a flow path between the inlet flow port and the flow sensing region that is contorted in three-dimensions. The three-dimensional contorted flow path between the inlet flow port and a flow sensing region may include a particle collection region that is configured to decelerate a fluid and collect particles that are released from the fluid. The deceleration of the fluid flow and/or one or more changes in the direction of fluid flow along the contorted three-dimensional flow path may cause dust and/or other particulate matter to be released from the fluid prior to reaching a sensor in the sensing region.

摘要： A flow sensor assembly includes a housing that defines an inlet port, an outlet port, a main channel and a bypass channel. An inlet flow channel fluidly connects the inlet port of the flow sensor assembly to the main channel and an outlet flow channel fluidly connects the main channel to the outlet port. A bypass feeder input channel fluidly connects the main channel to the bypass channel and a bypass feeder output channel fluidly connect the bypass channel to the main channel. In some instances, at least 40 percent of an input pressure differential applied between the inlet port and the outlet port of the flow sensor assembly drops across the inlet flow channel and the outlet flow channel collectively. A sensor is exposed to a fluid in the bypass channel and senses a measure related to a flow rate of the fluid flowing through the bypass channel.
