bg9.png (Multiple-choice question) When installing an electromagnetic flowmeter, the following must be met ( ). A. The flow meter must be installed horizontally or vertically. B. The converter unit must be grounded. C. The installation location should be far away from any magnetic sources. D. The straight pipe section upstream of the meter must be at least 5D in length. The correct answers can be seen after submission; points are awarded if the answer is correct or if the key points are addressed. The answers are: A, B, C, D. —————————————————————————————————————————————————————————————— The validity period for this question is one week; no scoring will be given after that deadline, which is 207.08.22. Scoring criteria: Incorrect answers earn 1 wealth point; incomplete answers earn 2–6 points. Correct answers with detailed explanations earn 8 wealth points, while correct answers with insufficient additional details earn 10–15 wealth points. Please score according to these criteria. Note: If there are editing records after answering, only those who participated will be given points. For continuous malicious spamming, 2 points will be deducted each time, with no upper limit. Pure numbers, pure emojis, or random letters that have nothing to do with the answer are all considered malicious spamming. Points will start to be deducted after three warnings.

This type of question seems to relate to exam-oriented education; the standard answers are likely A, B, C, and D. However: Flowmeters that are not installed horizontally or vertically, those whose converter units are not grounded, those located in areas with many magnetic sources, and those with an upstream straight pipe section shorter than 5D can still operate properly. As required by the standard answers, there are cases where they function well as well as cases where they do not; even when the conditions are not met, some flowmeters still work properly while others do not. It’s important to adapt to the actual situation – ideal conditions do not always exist on site. One should not be too strict in following rules, as this could lead to misunderstandings: it’s not true that such flowmeters cannot be used at all, or that they will definitely not work properly. It all depends on the results; it’s best to have supporting evidence. We haven’t done it absolutely in this way either; it has been operating for over a decade, and some measurements are still based on trade standards, with annual comparisons using large containers also yielding decent results.

The questions are aimed at technicians at different levels; all of them require a high level of technical skill, so the number of participants will inevitably be low. We should increase the popularity of the dashboard section, as the difficulty level of the questions isn’t constant
