    摘要： A differential pressure transducer is provided, having a tubular housing disposed between first and second connection elements. The housing includes an inflow section, a diffuser section, a constrictor section and an outflow section. The inflow section and the outflow section each have a flow cross-section with a first inner diameter. In the direction of fluid flow, the diffuser section has an inner diameter that continuously increases up to a second inner diameter, while the constrictor section has an inner diameter that continuously decreases down to the first inner diameter. An equalization tube is connected between the first connection element and the inflow section of the housing. A quotient of an inner length and an inner diameter of the equalization tube is at least 2.5. A plurality of openings extend through the housing and are fitted with coupling elements for connection to impulse lines or sensors.

    摘要： The present disclosure provides improved process measurement assemblies and methods for replacing/installing devices/instruments (e.g., gauges, digital gauges, transducers, switches, etc.) associated with process measurement assemblies. More particularly, the present disclosure provides improved process measurement assemblies (e.g., diaphragm seal assemblies or isolation ring assemblies) having couplings (e.g., dry-break couplings) that allow a user to replace and/or install process measurement instruments/devices to and/or from the process measurement assemblies, and related methods of use. In general, the present disclosure provides for improved systems/methods for installing or replacing a process measurement instrument to and/or from process measurement assemblies (e.g., diaphragm seal assemblies or isolation ring assemblies). In exemplary embodiments, the present disclosure provides for a system/method for installing/replacing a process measurement instrument wherein the process operating under pressure is a flow stream process, the flow stream process having a solids content.
