Abstract: A differential pressure sensor is a body with first and second interior channels connected to process fluid inlets and separated by a barrier. Each side of a MEMS pressure sensing diaphragm in the barrier is fluidly connected to a process fluid inlet. The diaphragm is mounted on a hollow pedestal such that one side of the diaphragm is fluidly connected to a process fluid inlet through an interior channel in the pedestal that is adhesively attached to an annular bottom of a cylindrical cavity inside the body. The other side of the diaphragm is fluidly connected to the other process fluid inlet and is fluidly isolated from the first fluid inlet by the adhesive at the bottom of the pedestal. Deformation of the diaphragm due to a pressure difference between the process fluid inlets detected by sensors on the diaphragm indicates a differential pressure.

Abstract: A metal terminal of a gas sensor includes a forward terminal member and a rear terminal member. The forward terminal member is made of a material superior in heat resistance to and greater in “0.2% yield strength” than a material of the rear terminal member. The forward terminal member has heat resistance suitable for a portion which comes into contact with a high-temperature detection element and is larger in an elastic deformation region than the rear terminal member, thereby providing good contact with the detection element and thus facilitating maintenance of electrical contact with the detection element. The rear terminal member is unlikely to have springback at a signal-wire connection portion to be connected to a lead wire, thereby facilitating maintenance of electrical connection with the lead wire.

Abstract: System, method, and apparatus embodiments characterize potential air emissions during the pig receiver depressurization. The mass flow rate, pressure, and temperature of exhaust gas released from the pig receiver are ascertained using a mass flow meter, pressure gauge, and temperature gauge, respectively. A flow meter and control valve regulate flow of exhaust gas through a sampling line and into a grab sample collection train. The grab sample collection train includes grab sample containers (e.g., piston cylinders, double-ended cylinders, and evacuated canisters) that collect exhaust gas samples over a range of pressures. The exhaust gas samples are used to determine the concentrations of gas components in the exhaust gas over the range of pressures. These concentrations are interpolated and/or extrapolated to provide a concentration versus pressure curve for each identified component in the exhaust gas.
