Abstract: A mass flow controller includes at least one conduit having a fluid inlet and a fluid outlet, the conduit defining a flow path along which the fluid flows. The mass flow controller also includes a modified inlet block having an inlet aperture, an inlet channel, and a reservoir fluidly coupled to the inlet channel and the conduit that enhances flow through the controller and improves rate-of-decay measurements. The mass flow controller includes at least one flow sensor that generates a flow sensor signal that is proportional to the mass flow rate of the fluid through the conduit. The mass flow controller includes a control subsystem coupled to a flow sensor and a valve assembly to control flow through the conduit.

Abstract: A flow sensor includes an auxiliary channel having an opening into which a fluid to be measured is taken; a sensor element that measures the flow of the fluid to be measured; a housing that accommodates electronic parts; and a resin cover. The flow sensor is configured such that junctions of the housing and the cover are formed in locations where first target weld portions, which are formed so that the circuit chamber is surrounded, face each other and second target weld portions, which are disposed for additional reinforcement of the joints, face each other on a bonding face of the housing and a bonding face of the cover with a step being provided. The positioning of the housing and the cover is determined, and the first target weld portions are welded to each other and second target weld portions are welded to each other by way of laser radiation.

Abstract: An airflow-rate detecting device capable of detecting humidity has a housing, a flow rate sensor, a humidity sensor, a humidity sensor case, and a dust separating portion. The housing therein defines a bypass passage into which a part of air flowing in a duct flows. The flow rate sensor is disposed in the bypass passage. The humidity sensor detects a humidity of air flowing in the duct at an outside of the housing. The humidity sensor case houses the humidity sensor and therein defines an interior space into which a part of air flowing in the duct flows as a target air of which humidity is detected by the humidity sensor. The dust separating portion removes dust from the target air before the target air flows into the interior space.

Abstract: A method of manufacturing a Coriolis mass flowmeter from a polymeric material is described, in which a dynamically responsive manifold is fabricated from the same material as the flow sensor's flow-sensitive elements. The flowmeter is free of mechanical joints and adhesives. The manifold and flow-sensitive elements therefore do not slip or change their location relative one another, nor are they subject to differing degrees of thermal expansion that would otherwise undermine integrity, reliability, and/or accuracy of the boundary condition at the ends of the vibrating flow-sensitive elements.

Abstract: In a flow meter with a displacement meter (1) a parallel-connected pressure difference sensor (3) has a bypass channel (8) which frees a connection between the inflow side and the outflow side (4, 5) when a piston (7) butts against a maximum stroke stop (9). In the bypass channel (8) is a check valve (11) which prevents the backflow from the outflow side to the inflow side (5, 4) and thus enables a return of the piston (7) purely due to pressure.

Abstract: The present invention provides a thermal flow meter 300 which reduces a stress applied from a fixing portion 3721, which is used to hold and fix a circuit package 400 with respect to a housing 302, to the circuit package 400 and has high reliability. In the thermal flow meter of the invention, the circuit package 400 embedded with a flow rate measurement circuit is formed through a first resin molding process, the fixing portion 3721 is formed along with the housing 302 through a second resin molding process, and the circuit package 400 is enveloped by the fixing portion 3721, whereby the circuit package 400 is held by and fixed to the housing 302. In order to reduce the influence of a stress, generated based on a temperature change of the fixing portion 3721, on the circuit package 400, the fixing portion 3721 is constituted of a thick portion 4714 and a thin portion 4710. Since thickness of a resin of the thin portion 4710 is small, the stress to be generated is small, and a force applied to the circuit package 400 can be reduced.

Abstract: The dispenser disclosed herein serves a single serving of a powdered nutrient contained within a container having multi-servings of the powdered nutrient. The dispenser has a metering device that operates as a ball valve or guillotine to dispense a single serving of the powdered nutrient into a water container. The dispenser also has a support surface that can be lowered and raised back up in order to fit a water container under the metering device and a distal tip of the metering device into a mouth of the water container so that no powdered nutrient spills out of the water container during transfer of the powdered nutrient from the metering device to the water container.
