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.

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 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 pressure sensor assembly having a printed circuit board (PCB) with a pressure sensor and a ring mounted on the PCB. The pressure sensor assembly may include a force transmitting member positioned at least partially within the ring. The force transmitting member may transfer a force applied to a front side of the force transmitting member to a front side of the pressure sensor. For example, the force transmitting member may be exposed to a fluid within a reservoir or other sensed media and may transmit forces of the fluid and/or other sensed media to the pressure sensor. The force transmitting member may include a biocompatible material to facilitate use of the pressure sensor assembly in medical and/or food related applications. One example biocompatible material usable in the force transmitting member may be cured silicone elastomer.

摘要： A flow sensor assembly includes a flow sensor for sensing a flow parameter. The flow sensor may provide a flow sensor output signal that is related to the sensed parameter. A control block operatively connected to the flow sensor may receive a measure related to the flow rate of the fluid stream and drive the heater of the flow sensor to a heater temperature, such that the heater temperature may be dependent on the flow rate of the fluid stream, which causes the analog output of the flow sensor to be relatively linear over an expected operating range of flow rates.
