摘要： The invention relates to a Coriolis flow sensor. The sensor comprises a housing and at least a Coriolis-tube with at least two ends being fixed in a tube fixation means. The flow sensor comprises excitation means for causing the tube to oscillate, as well as detection means for detecting at least a measure of displacements of parts of the tube during operation. According to the invention, the Coriolis flow sensor comprises a reference mass, as well as further excitation means arranged for causing the reference mass to oscillate during operation, as well as further detection means for detecting at least a measure of displacements of the reference mass during operation. Additionally, control means are provided for controlling the excitation means and/or further excitation means based on vibrations measured by the detection means and/or further detection means. This way a Coriolis flow sensor with active vibration isolation is obtained.

摘要： The physical quantity sensor subassembly has a preformed part, a wiring member, and an outer resin portion. The preformed part includes a physical quantity sensing element configured to detect a physical quantity other than a flow rate of the gas to be measured, a wiring terminal electrically connected to the physical quantity sensing element, a concave portion in which the gas to be measured is introduced, and an inner resin portion is molded around the physical quantity sensing element and the wiring terminal to be integral with the physical quantity sensing element and the wiring terminal. A sensing surface is exposed at the concave portion. The wiring member is electrically connected to the wiring terminal of the preformed part. An outer resin portion includes an opening hole portion communicating with the concave portion, and is molded around the preformed part, the wiring member, and an electrically connected portion between the preformed part and the wiring member.

摘要： A process variable transmitter for sensing a process variable of process fluid in an industrial process includes a process gasket having a surface configured to form a seal with a process vessel face. The process gasket is exposed to the process fluid through an opening in the process vessel face. A process variable sensor is carried by the process gasket and configured to sense a process variable of the process fluid and provide a sensor output. Measurement circuitry coupled to the process variable sensor provides a process variable transmitter output related to the process variable output.

摘要： A method of determining flow parameters of a streaming gas in a conduit for medical applications. Longitudinal waves are generated in a transmitter connected from outside to a conduit. These waves are transmitted along two diagonal paths through the streaming medium in an upstream and a downstream direction, and received by two receivers which are located in a diagonal upstream and downstream position and on an opposite side relative to the transmitter, also connected to the conduit. A transit time value of the waves between the transmitter and each of the receivers is determined. A difference value on the basis of the determined transit time values is generated and the flow parameters are determined on the basis of the difference value. This measuring method is highly independent of the propagation velocity of the wave in the medium streaming in the conduit therefore also independent of the temperature and humidity of a gaseous medium.

摘要： A case (330) for a vibrating meter (300) is provided. The case (330) includes a first panel (331a) defined by at least a first edge (333) and a second edge (334). The case (330) also includes one or more indentations (332) formed in the first panel (331a). The one or more indentations (332) include at least a portion extending from the first edge (333) to the second edge (334). The resonant frequencies of the case can be increased and separated from the intended drive frequencies of the fluid conduits (306A, 306B).

摘要： A gas flow indicator device (10) has an elongate housing (12) defining a chamber (20) enabling gas flow from an inlet (22) at a first end (16) to an outlet (24) at a second end (18). An indicator member (26) within the chamber (20) extends from adjacent the first end (16) over part of the length of the chamber (20) and is of annular form enabling gas to enter the chamber along a bore (28) through the indicator member (26). The indicator member (26) is spaced from an inner surface (30) of a peripheral sidewall (14) of the housing (12) to define an annular space (32) within the chamber (20). A concealment member (34) is movable from the first end (16) by a sufficient pressure generated by gas flow through the chamber (20), against a biasing member (36) acting to bias the concealment member (34) to the first end (16). An annular skirt (38) of the concealment member (34) is receivable into the annular space (32) so one end (40) of the skirt (38) provides a seal against an annular surface (42) at an end wall (44) at the first end (16), while a transverse wall (48) at the other end (46) of the concealment member (34) defines an opening (50) providing resistance to gas flow. The one end (40) of the skirt (38) can be held in sealing engagement at the annular surface (42) to conceal the indicator member (26) from view through an adjacent window (52) of the housing (12). Increasing gas flow rate to achieve the sufficient pressure overcomes the bias, enabling the concealment member (34) to move towards the second end (18), exposing the indicator member (26) to view through the window (52), and thereby providing a visual indication of gas flow.

摘要： A meter box and lid unit has a meter box. The meter box has end walls and opposing side walls, an interior cavity and an opening. A lip extends along the walls. The lip has notches therein. The lid has a first portion and a separate second portion, the first and second portions covering the opening when the lid bears the lip. The first portion has a receptacle for receiving a transmitter. The first portion has retainers depending therefrom. The first portion is capable of moving from a first position to a second position, wherein when the first portion in the first position, the retainer and the notch are aligned and the first portion can be removed from the box. With the first portion in the second position, the retainer cooperates with the lip to retain the first portion on the lip. With the first portion in the second position, the second portion can be removed from the box while the first portion is retained thereon.

摘要： A metal mold includes a restraining part that is fitted in a recess provided at a part of surfaces of at least two resin parts that serves as an outer surface of a resin hollow body. A linear space is filled with high-pressure resin fluid injected at a predetermined injection pressure. The resin parts are joined together. The mold receives injection pressure of resin fluid, with which the space is filled, through the resin parts, and applies pressing force, which pushes back the resin parts toward the space, to the resin parts as reaction force against injection pressure. Stress is produced on a hollow wall surface in a direction in which the wall surface projects into a hollow portion due to injection pressure. The restraining part applies pressing force to the resin parts in a direction opposite from the stress projecting the wall surface into the hollow portion.

摘要： A flow sensor sub-assembly includes a flow tube having a lumen, an outside diameter, a first end, and a second end. An inlet fitting includes a conical orifice sized for insertion in either end of the flow tube, such that an internal passage of the inlet fitting is coaxial and concentric with the lumen and the end of the flow tube abuts a shoulder. An outlet fitting includes a conical orifice sized for insertion in either end of the flow tube, such that an internal passage of the inlet fitting is coaxial and concentric with the lumen and the end of the flow tube abuts a shoulder. A first piezo element integrated with the inlet fitting is arranged at an upstream position of the flow tube assembly and a second piezo element integrated with the outlet fitting is arranged at a downstream position of the flow tube assembly.
