A pressure sensor assembly and method of manufacturing the same are provided. The pressure sensor assembly includes a contoured sensing insert. The contoured sensing insert includes an outer sensing insert having an open interior through-hole and a top contoured surface configured to be secured at least partially within the fluid flow container. The top contoured surface has a surface contour corresponding with an interior wall contour of the fluid flow container. The contoured sensing insert also includes an inner sensing medium defined within the through-hole of the outer sensing insert. The inner sensing medium defines a conforming contoured surface at least substantially matching the surface contour of the top contoured surface. A corresponding method of manufacturing is also provided.

A flow path cassette includes superimposed first and second flexible sheets, where a plurality of flow paths are disposed therebetween and detection channel portions are disposed at one or more points along one or more of the plurality the flow paths. Each of the detection channel portions includes a first bulging portion and an opposing second bulging portion. A plate member is aligned with the second bulging portion, and a deformation preventative member is aligned with the first bulging portion. The plate member may move with the second bulging portion, while the deformation preventative member prevents deformation of the first bulging portion.

Methods, systems, and apparatuses are provided for detecting and determining conditions of and conditions within a fluid conduit.

A fluid device comprising a body with a membrane extending in a mean plane and showing an inner face and an outer face; a strain gauge arranged on the outer face of the membrane for measuring a deformation of the membrane when a fluid pressure is applied on the inner face thereof; wherein a bore is formed in the body, extending along an axis parallel to the mean plane of the membrane and delimiting a passage for the fluid under pressure, in fluid connection with the inner face of the membrane.

Sensing systems, connectors, and methods include a housing, including a sensor and a locking mechanism, a junction, and a membrane. The junction includes a fluid inlet, a fluid outlet, and a receiving mechanism. The receiving mechanism is removably attachable to the locking mechanism. The membrane is disposed within the junction, and is in fluid communication with the fluid inlet and the fluid outlet. The sensor senses a property of a fluid across the membrane when the locking mechanism is attached to the receiving mechanism.

A pressure measurement pod for use in blood circuits includes a pressure sensing pod defining a chamber and having a rigid wall portion and an integral flexible wall portion forming a flexible, moveable, fluid-impermeable diaphragm with a first major side thereof facing an interior of the chamber and a second major side opposite the first major side. The second major side faces outwardly away from the chamber, and the pod has ports on sides of the chamber. The internal surfaces of the chamber and ports are shaped such that any contour following the internal surfaces to the outside of one of the ports traces only surfaces characterized by positive or neutral draft angles such that invasive mold portions may be withdrawn through the ports thereby permitting the pressure measurement pod to be molded in a single shot molding process.

An analytical toilet is disclosed, having a bowl for receiving excreta supported by a base. The toilet also includes a pressure sensor mounting fixture, which has: a chamber with an outlet. The chamber is in fluid communication with the contents of the bowl through the outlet. The pressure sensor mounting fixture also has a pressure sensor cavity above the chamber having an inlet in fluid communication with the chamber such that an air bubble is maintained in the pressure sensor cavity. A pressure sensor is included that is adapted to measure the pressure in the pressure sensor cavity. Also, a system is disclosed for measuring changes in the volume in a toilet bowl. The system includes a pressure sensor mounting fixture, having a chamber with an outlet. The chamber is in fluid communication with the contents of the bowl through the outlet. The pressure sensor mounting fixture also has a pressure sensor cavity above the chamber having an inlet in fluid communication with the chamber such that an air bubble is maintained in the pressure sensor cavity. A pressure sensor is included that is adapted to measure the pressure in the pressure sensor cavity.

A system monitors gas flow and pressure to a gas appliance in a fluid network comprising an analyzer. The analyzer has a housing defining an inlet, an outlet, and an interior in fluid communication with the inlet and the outlet. At least one sensor is coupled to the analyzer and configured to generate at least one signal related to gas being supplied to the gas appliance. A smart device communicates with the analyzer, wherein the smart device has a user interface and is configured to monitor, store and display data. The smart device can present any or all of a plurality of parameters such as the flow of gas, a capacity of the flow of gas, a temperature, a pressure of the gas and the like to a user based on signals from sensors.

An integrated sensor and service port for HVAC (heating, ventilating, and air conditioning) equipment or an HVAC system. The integrated sensor and service port may comprise an anti-blowback mechanism.

A measurement chamber that is essentially dome shaped and has a base area with a membrane and has at least two connection points fora fluid flow. The measurement chamber has two outer webs opposite each other, one of the webs engaging a clamping edge of a coupling element.
