摘要： An arrangement includes a pipeline and a Coriolis volumetric flow meter for measuring a mass flow rate of a medium flowing through the pipeline. A first pressure sensor is attached at an inlet-side of the pipeline and a second pressure sensor is attached at an outlet-side of the pipeline, or wherein a differential pressure sensor is configured to detect a difference between an inlet-side and an outlet-side. The pressure sensors and/or the differential pressure sensor are configured to measure a media pressure and to determine, for each differential pressure, a volumetric flow velocity of the medium through the pipeline. A first monitoring sensor is attached at an inlet-side portion of the pipeline and a second monitoring sensor is attached at an outlet-side portion of the pipeline, wherein the monitoring sensors are configured to monitor a measurement variable different from the media pressure to identify a static media state.

摘要： A flow meter run offers autonomous operation whilst improving measurement performance & confidence, increased safety and improving the total cost of ownership. A plurality of isolation valve assemblies each offer DBB (Double Block & Bleed) isolation to isolate a component or meter run section. This DBB isolation includes components being extracted from the main metering line. The meter run philosophy is detailed with use of a novel rotational orifice meter, though other flow meters may be substituted. The flow meter run also features extractable filters, a rotational and extractable flow conditioner which includes open and blind isolation components. The rotational orifice meter can house several independent orifice plates or nozzles and extractable sample probes and temperature elements. Further instrument sensors include the direct (non-inferred) measurement of density and/or viscosity. The system is configured for multiple sensors to monitor performance, autonomy, validation and isolation.

摘要： A system includes a flow tube configured to receive a flow measured by an ultrasonic flow measurement, wherein a center region of the flow tube is configured to have a drop in pressure. The system also includes a heat source/hot wire and temperature sensors configured to enable a flow measured by a thermal massflow measurement. In the system, a controller is configured to compare the flow measured by the ultrasonic flow measurement to the flow measured by the thermal massflow measurement. The controller determines a ratio of the flow measured by an ultrasonic flow measurement to the flow measured on by the flow measurement based on thermal massflow. The controller also calculates a density, a thermal conductivity and an energy and/or gas content of the gas.
