  • Primary Standard Gas Flow Calibration—The Only Guarantee of Accuracy

    At Sierra, we have a saying: “An instrument’s accuracy is only as good as its calibration.” The accuracy of your mass flow controller (MFC) is essential in assuring the efficiency, performance, and quality of your flow meter. In many cases, if your instrumentation is not calibrated, then a decline in performance is possible due to ...

  • A CFD study of the effect of venturi geometry on high pressure wet gas metering

    Venturi meter is increasingly being preferred as wet gas flow meter because of its simple construction and ease of operation. It has been found that the performance of venturi in single phase gas is very different from that of water. In this work, with a view to optimise the design, the effects of diameter, diameter ratio and convergent angle on the performance of a venturi meter for wet gas ...

  • Measuring and interpreting gas flow from landfill boreholes case study

    Current landfill gas measurement practice for measuring the gas composition is well understood, and there are standard procedures and instruments available to analyse the gas. It is also current recognised practice to measure the gas 'flow' from boreholes to monitor the production of gas in a landfill site. If care is taken to make the measurement in the same way each time, changes in the ...

  • Gas Mass Flow Control: Why Thermal Mass Flow Technology is Recommended for Best Accuracy!

    It’s no secret. Price, but perhaps more importantly, performance, drive every new product acquisition you make.  How important is measurement accuracy and control to your lab experiment or industrial process? It’s critical.  If your flow readings are off or the flow is not controlled with precise accuracy your research is compromised, product quality suffers, and processes ...

  • Industrial thermal mass flow meters Pt.1 -Pt.2 - measurement & control

    An industrial thermal mass flowmeter measures either the mass velocity at a point in a flowing gas or the total mass flow rate through a channel or pipe. Figure 1 shows a typical thermal mass flow sensing element. It consists of two sensors: a mass flow sensor and a temperature sensor, which automatically corrects for changes in gas temperature. Both sensors are reference- grade platinum ...

  • Capillary Tube Thermal Mass Flow Meters & Controllers - A User`S Guide - White Paper

    Abstract Capillary tube thermal mass flow meters directly measure the mass flow rate of clean gases and gas mixtures in lower flow ranges. A capillary tube thermal mass flow controller adds an integrally mounted flow control valve to the flow body of the mass flow meter and bom monitors the mass flow rate and controls it to be equal to a set-point value selected by the user. ...

  • Non-contacting solution for Plugged off flow meters in the oil patch - Case Study

    For years Petrobakken Energy Ltd. used inline turbine flow meters to track the flow rate of oil recycled to treaters. But with a high concentration of wax and sand in the oil, the turbine meters were quickly plugging off. The line had to be shut down at least once a day and the turbine flowmeters disassembled for cleaning. This was troublesome and expensive. Petrobakken knew there had to be a ...

  • Overcoming Natural Gas Sampling Challenges in Oil & Gas Applications

    It is a fact that in order to comply with various government rules and regulations, oil and gas companies have to continually take natural gas samples to prove the gas composition and amount of gas flowing in their oil fields. The challenge comes in trying to actually take an adequate gas sample representative of the gas flow. First, engineers must carefully consider where the ...

  • Two Technologies for Flow Measurement from Outside a Pipe

    Doppler and Transit Time are two very popular types of flow meter for non-invasive measurement of flow in full pipes. We tend to confuse these technologies because they are both ultrasonic and both measure flow by using sensors clamped onto the outside of a pipe. In the real world they actually work best in opposite applications. Success in your installation depends on understanding the ...

  • Smart meters: Truly a cure for energy blindness?

    And now for a dose of reality.   No doubt smart meters are a good thing, but even their most ardent fans must admit that a degree of hoopla surrounds these little digital boxes. We hear that if consumers can just see how much power they use in real time, and what it costs, our energy woes will be no more.   Smart meters will even cure the blind. The energy blind that ...
