Abstract: A humidification system comprises a first sensor and a second sensor. The first and second sensors are adapted to sense flow characteristics within the system. The first and second sensors are isolated from the flow by barriers formed by respective first and second sealing members. The sealing members extend through apertures formed in the system and have a portion that contacts the sensing elements of the respective first and second sensors. A cartridge can hold the sensors and provide repeatable penetration depths into a flow passage of the system. A medical tube has a composite structure made of two or more distinct components that are spirally wound to form an elongate tube. One component can be a spirally wound elongate hollow body; the other component can be an elongate structural component spirally wound between turns of the spirally wound hollow body.

Abstract: Disclosed is a fast-response sensor system to measure a fluid vector in a plurality of dimensions. This system, known as ‘MAST’ (for MEMS Anemometry Sensing Tower), utilizes microelectromechanical (MEMS) hot-wire devices to produce a solid-state, lightweight, and robust flow sensor system suitable for, e.g., real-time wind estimation onboard a UAV. The MAST uses three through eighteen polygonally-arranged microscale flow sensors to determine the fluid's vector's direction and magnitude.

Abstract: A sensor unit for measuring a mass flow rate of a liquid hot-melt adhesive is disclosed. The sensor unit includes a flow channel for the hot-melt adhesive, a first temperature measurement device positioned at a first position in the flow channel, a second temperature measurement device positioned at a second position in the flow channel and a heating device assigned to the second temperature measurement device, and a control unit for controlling the heating device and for measuring the mass flow rate. The controller is configured to adjust the temperature of the heating device assigned to the second temperature measurement device to a value, to determine the heating power for heating the heating device assigned to the second temperature measurement device, and to calculate the mass flow rate in the flow channel. The first and second temperature measurement devices are arranged substantially parallel to each other in the flow channel.

Abstract: A flow measuring device includes a housing including a bypass passage and a flow sensing chip located in the bypass passage and including a sensing surface portion. A throttle portion that is a part of a flowing passage wall facing a sensing surface portion throttles a cross-sectional area of a bypass passage. A position where the throttle portion starts is referred to as a start point position, and a position of the throttle portion where a distance between a gravity center of the sensing surface portion and the throttle portion is shortest is referred to as an end point position. The start point position and the end point position define an imagination line, and the imagination line and the flowing direction define an angle that is in a range from 0 degrees to 20 degrees.
