The Resolution Gap: Why Space-Based Sensors Struggle with Forensic Accuracy Satellites primarily identify that a plume exists, but often cannot attribute causation or precisely quantify mass flow. This creates regulatory risk when satellite estimates are used as the basis for enforcement decisions. ...

The industry is shifting toward Empirical Verification the ability to measure the exact mass flow of a leak in real time. This analysis examines the evolution of Quantitative Optical Gas Imaging QOGI, the economic case for replacing default emission factors with empirical data, and how high performance methane detection cameras serve as a financial defense in the ...

AQUA DESIGNER incorporates the experience of many German and international engineering firms and consultants. The guided calculation process provides a highly customised plant design for your individual project. ...
The preparation of accurate calibration gas standards depends on the precise regulation of gas flows by devices known as mass flow controllers (MFCs). Ensuring MFCs are performing accurately requires careful evaluation of each process mass flow’s gas conversion factors (known as K-factors or GCF). Here, we ...
Because long straight pipe runs are difficult to find in these installations, varying flow profiles within the pipe degrade measurement accuracy. Furthermore, both the orifice and the turbine meter measure only volumetric flow. Additional pressure, temperature, and differential pressure sensors as well as a flow computer are required to ...
SIERRA’S SOLUTION With the capability of measuring five flow parameters with one process connection and calculating true mass flow directly with integral temperature and pressure sensors, Sierra’s InnovaMass® vortex meters provide an optimal solution. Sierra was the first to invent a multivariable ...
This vortex mass flow device directly measures three parameters. Then, it computes seven more properties of liquids, gases, and steam. ...
Olin, Founder and Chairman of the Board of Sierra Instruments about the evolution of thermal mass flow meters and his latest product in this technology. Gases & Instrumentation: You have been engaged in thermal mass flow technology for a number of years. ...
The biggest cause for concern, however, is that orifice and turbine meters measure volumetric flow. Additional pressure, temperature and differential pressure sensors, as well as a flow computer, are required to calculate or infer mass flow (Figure 2). ...
Both technologies are prone to clogging. The mass flow advantage Thermal mass flow meters are ideal for natural gas combustion and allocation applications because mass flow rate, not volumetric, is the quantity of direct interest. ...
So What Type of Flow Meter Technology Should You Choose for the Highest Accuracy? Competitive “indirect-type” mass flow measurement technologies—like differential pressure devices that boast speed as the most important factor—can only measure volumetric flow and must calculate ...
Even a “small” change of 10% in steam pressure will result in a 10% error in non-compensated mass flow. This means that, in a typical differential pressure measurement installation, the volumetric flow rate measured by the device must be compensated by measuring temperature and pressure, and then these three measurements (ΔP, T ...
We use a volumetric vortex meter with a constant density programmed for the mass flow calculations. The physics tells us that when temperature and pressure change in the line mass flow also changes quite dramatically. Let’s see why. Volumetric vortex flow meters use density to ...
As I go through the day looking at various mass flow applications, I often notice that it is very easy for users to overlook one of the crucial items required for calculating mass flow. ...
In 1997, Sierra Instruments took proven vortex shedding technology to the next level with the launch of the Innova-Mass® Model 240 & Model 241 Multivariable Mass Vortex Flow Meter. ...
Gardner-Denver recommends that ACS technicians use Sierra Instruments’ thermal mass flowmeters for accurate mass flow measurement of compressed air. ...
Based on the minimum entropy generation rate and by applying a number of geometrical constraints, as well as using a search method, the optimum apparatus's dimensions and the secondary air discharge and the primary air mass flow rates are calculated. The numerical results show that, to increase the cooling load of an indirect evaporative cooler, ...
Cycle exergy efficiency, net power output and exergy destruction have been calculated for different mass flow rates and temperature of the injected steam. The range of variation of the mass flow rate was between 0 and 5.24% of the design air flow rate, and the temperature of the injected steam ...
The effective porosity is a required parameter for the mass flow rate calculations in groundwater hydrogeology. It is also a useful parameter in geotechnical engineering. ...
