【Weekly 3 Questions, Question 7】2017.8.24

bg9.png(Question) When an electromagnetic flowmeter is in operation, if the signal becomes weaker or drops suddenly, what are the main reasons for this? Note: If the question is ambiguous, please contact me privately; however, I will not address overly complex issues nor provide explanations related to individual words. The answer is: The main reason is that the insulation between the electrodes deteriorates or becomes short-circuited. The reason for this phenomenon is 1: dirt may have accumulated on the inner wall of the measurement catheter, which should be cleaned and the electrodes wiped ； 2. The lining of the measurement conduit may have been damaged by burning and should be replaced. 3. The signal socket may be corroded and should be cleaned or replaced. —————————————————————————————————————————————————————————————— The deadline for submitting answers is one week; no scoring will be given after that period. Once the deadline passes, the answers will be displayed automatically. The deadline is 207.08.31. Scoring criteria: 2 Wealth points for incorrect answers; 3–6 points for *incomplete* answers; 8 Wealth points for correct answers accompanied by detailed explanations; 10–15 Wealth points for correct answers with additional *complementary* information. 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 unrelated to the answer are all considered malicious spamming; points will start to be deducted after three warnings.
The main cause of the above situation is poor insulation or short-circuiting between the electrodes. When such a situation is detected, several factors should be considered: 1) There may be dirt deposited on the inner wall of the conduit, which should be cleaned and the electrodes wiped. 2) The lining of the measurement conduit may be damaged and should be replaced. 3) The signal socket may be corroded and should be cleaned or replaced.
(1) If dirt has accumulated on the inner wall of the measurement conduit, it should be replaced; (2) The signal socket may be corroded and should be cleaned or replaced; (3) The lining of the measurement conduit may be damaged and should be replaced.
Answer: 1. There may be dirt deposited on the inner wall of the measuring conduit. 2. The signal socket may be corroded. 3. The lining of the measurement conduit may be damaged.

1. Electromagnetic interference 2. Grounding fault 3. Coil corrosion 4. Control valve failure
The insulation between the electrodes deteriorates or gets short-circuited. The reason for this phenomenon is 1: dirt may have accumulated on the inner wall of the measurement catheter, which should be cleaned and the electrodes wiped ； 2. The lining of the measurement conduit may have been damaged by burning and should be replaced. 3. The signal socket may be corroded and should be cleaned or replaced.
