It’s a hassle when an electromagnetic flowmeter malfunctions. Minor issues are easy to resolve, but when serious problems arise, it’s difficult to know what to do. Below, we list the common problems reported by after-sales staff and those observed on site, along with some solutions for dealing with them. The ten most common routine problems that occur on-site are as follows: 1. Why is a negative flow rate displayed on the LCD screen? Answer: The coils inside are connected in the wrong order; go to the gauge’s settings and change the setting from positive flow to negative flow. 2. What should I do if I don’t have straight pipe sections of appropriate length at both ends at the installation site? Answer: Creating a bypass ensures the presence of straight pipe sections and also facilitates subsequent maintenance. 3. Is this precision valid for the entire flow range? Answer: This accuracy refers to a reasonably appropriate range in the middle; at the upper and lower limits of the range, the accuracy is slightly lower. 4. Why isn’t the LCD screen lighting up? Answer: First, check whether the fuse behind the electromagnetic flowmeter is damaged; if it’s not damaged, then there is a problem with the circuit board. 5. Will the values fluctuate after it is connected to the site? Answer: The electromagnetic interference in the vicinity is too strong, and no grounding measures have been taken, etc. 6. What is the difference between integrated and separate types? Answer: The integrated type displays the information on-site, while the separate type can be placed in a control room for viewing. 7. Why do flow meters used for measuring sewage fail to generate data over time or provide inaccurate readings? Answer: It is possible that the electrodes are covered with sludge or have been damaged; regular maintenance is recommended. 8. Why is there no reading from the flow meter at my site? Answer: Reasons related to the medium: insufficient water content, inadequate conductivity, too low flow rate, or the pipe not being fully filled. 9. What’s the reason for the discrepancy between the measurement value and the output value of an electromagnetic flowmeter? Answer: Insufficient flow control, too low flow rate, damaged converter, exceeding the process limits. 10. Can dissatisfaction be measured? Answer: Theoretically, it is possible, but the measurement accuracy is not precise enough to meet the requirements.
