How to install the electromagnetic flowmeter? Do you know these common mistakes in installation?

Now that the weather is getting warmer, it is also the peak season for major manufacturers to purchase electromagnetic flowmeters after the holiday. The installation of electromagnetic flowmeters is very important. Many manufacturers just call a few workers to see which side is easy to install and do not take up space for installation. In fact, it is not right. , There are still many misunderstandings in installation like this. The following editor will introduce some common misunderstandings in the installation of electromagnetic flowmeters. Typical installation misunderstandings 1. The flow measurement value fluctuates greatly: the number keeps beating, and the flow value is unstable. Analysis: This happens mostly because there is a pump next to the flow meter at the installation site as shown in Figure 1. The medium is in turbulent flow as it passes through the flow, and the pump can interfere with the flowmeter measurement, resulting in unstable measurement results. Solution: Install the flowmeter in an environment away from the pump and other interference factors, and ensure the length of the straight pipe section to ensure the stability of the fluid. Figure 12. The problem of inaccurate measurement values: the measurement results are inaccurate, and sometimes there will be an empty pipe alarm. Analysis: Due to the incorrect installation position, installation at the outlet will cause the flowmeter to be dissatisfied with the pipe, which will cause an empty pipe alarm and inaccurate measurement. Solution: If the position is not enough, you can add an elbow at the outlet to ensure that the medium is full as shown in Figure 2. Figure 2 Influence of wrong installation 1. If the installation is not in the correct position, it will cause bubbles in the pipeline and dissatisfaction, which will affect the measurement accuracy of the electromagnetic flowmeter. For example, the medium measured in the pipeline is 'alcohol'. How much damage does the business bring. 2. If it is a new factory, the wrong installation will affect the factory to delay the test machine. This will bring losses to the business.
