Nine common questions about using turbine flowmeters to measure pure water

Thread Content

A turbine flowmeter is a device used for measuring pure water. It features high accuracy, good repeatability, a simple structure, low pressure loss, and easy maintenance, making it widely used in the water treatment industry. Qingtian Instruments shares nine common questions and answers regarding the use of turbine flowmeters for measuring pure water. 1. Why is a negative value displayed sometimes after connection? Answer: It was installed backwards; two-way measurement can be used. 2. I don’t have straight pipe sections of appropriate length in front of and behind the site – what should I do? 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 do the values fluctuate after it is connected on-site? Answer: The electromagnetic interference in the vicinity is too strong, and grounding measures were not taken, etc. 5. What is the difference between integrated and separate types? Answer: It is determined by the installation conditions on site. 6. Why do flow meters used for measuring sewage fail to generate data over time or provide inaccurate readings? Answer: It may be that the electrodes are covered by sludge or have been damaged; regular maintenance is recommended. 7. Why is there no reading from the flow meter at my site? Answer: Reasons related to the medium: insufficient water content, low electrical conductivity, too low flow rate, or the pipe not being fully filled. 8. What’s the reason for the discrepancy between the measured value and the output value? Answer: Insufficient flow control, too low flow rate, damaged converter, out of range. 9. Why is there traffic displayed after connecting? Answer: The pipe is not filled with liquid or contains bubbles; it may seem subjectively that there is no flow of liquid in the pump when in fact there is slight flow; issues related to the liquid itself (such as poor uniformity in its electrical conductivity or electrode contamination, etc.)
