Design a real-time temperature measurement system, which will be used to measure

Question

Design a real-time temperature measurement system, which will be used to measure the surface temperature of natural gas pipeline. The pipelines carry the extracted gas with higher temperatures to the liquefaction chambers hence the liquefied gas has a temperature of -162 degree C. Consider Gas pipeline surface temperature varies from -162 degree C to 40 degree C. Constraints: The temperature monitoring system should be robust and can withstand the temperature extremes at the surface of gas pipeline. Maintain an over-all uncertainly of

Real-Time Measurement Systems

Real-time measurement systems provide data quickly enough to affect the progress of field work.

Real-time measurement systems represent the third leg of the Triad approach. They are essential for implementing dynamic work strategies because they feed timely data to the decision-making process.

The Triad approach is only possible because of the tremendous technological changes that have occurred in the area of sample acquisition and real-time measurement systems in the last decade. The innovation rate in this area has been rapid. The pace will likely continue in the years ahead. As the case studies illustrate, the use of real-time measurement systems to support characterization and remediation work at hazardous waste sites is not a new concept. The Triad provides a technically defensible context in which to select and deploy real-time measurement technologies.

For this section's purposes, the term "real-time measurement systems" covers sample acquisition, analytical or measurement technologies, and data analysis/decision support tools. Example sample acquisition technologies include direct push technologies that can be equipped with sensor probes for acquiring subsurface information and Global Positioning System (GPS) technologies for quickly and easily establishing locational control in the field. Example "real-time" analytical methods include X-ray Fluorescence (XRF), portable gas chromatograph and mass spectroscopy (GC-MS) technologies, and immunoassay test kits

These systems share a common feature in that they interact with devices or processes that themselves operate based on real-world time. Such systems are often termed "hard real-time systems" because their actions must meet time constraints imposed by the application space, rather than by the operation of the measurement or control devices.

Examples of such hard real-time systems abound. In the measurement world, complex test systems composed of many electronic instruments operating in concert are used to verify the performance of even more complex electronic or electromechanical devices such as radar systems, electronic engine controls, power generators, and heart pacemakers.

In the field of control, combinations of computers, controllers, sensors, and actuators collaborate to regulate printing presses, oil refineries, packaging machines, traffic lights, and home heating equipment. Communications systems operate to pass information from source to destination and are governed by the laws of physics, the operation of the communication protocols, and the vagaries of users, all of which result in unpredictable traffic flows.

The use of time in measurement and control is actually very familiar, as our everyday life seems to be governed by the clock. Alarm clocks have been with us for ages. Does there exist a businessman that can function without the ever-present meeting reminder pop-ups on the computer screen? Lawns are watered, coffee is brewed, and favorite television programs are recorded; all based on some sort of mechanical or electronic clock.
