Insertion
electromagnetic flowmeter products will have more attention points when they are used in practical applications. At present, such a product can be better used in all industries, because the product itself has the characteristics of no resistance or no damage, which can fully reduce the resistance in the pipeline and meet the requirements of energy saving and consumption reduction. What kind of application does the insertion electromagnetic flowmeter have in the process of flow use? Whether it is a split type, an integrated type, or a plug-in type, the installation methods are different, so we must consider what to pay attention to before installation. We cannot reinstall it because of small mistakes. The following is based on the installation experience of the front-line operators. We share three points of attention: 1. The plug-in electromagnetic flowmeter product equipment can be installed in the liquid-filled position. When the installation is carried out, it can be effectively installed in the liquid-filled position to prevent the measurement pipe from having no liquid in it. The resulting illusion that the pointer is not at zero. In this case, it is best to install all equipment vertically, and to reduce the bubble error caused by the liquid flowing through the electrode when installing. 2. When the signal shielding product is installed between the transmitter and the converter, the interference to the signal must be avoided to the greatest extent possible. The signal between the transmitter and the converter must be output by shielded wire, and do not put the signal cable or the power cable in parallel in a steel pipe at the same time. The length of the signal cable is generally not more than 30 meters. 3. Reasonably control the installation location of the converter. When installing the converter, it is best to avoid the installation of strong magnetic fields of alternating current or direct current, and also to avoid the surrounding vibration environment temperature, generally controlled at minus 20 ℃ to 50 ℃. time, and can not contain corrosive gases as shown in Figure 1. The relative humidity should not be greater than about 80%. Figure 1 The main point to pay attention to the installation of the plug-in flowmeter is that the rod should be half of the pipeline. For example, the pipeline is DN600mm. At this time, it must be ensured that the inserted part of the rod is 300MM. Too long or too short will affect the accuracy and stability of the flowmeter, so it must be installed before installation. Considering this, when the plug-in electromagnetic flowmeter equipment is actually installed, what kind of installation requirements are there, these should consider the actual skills of the installer. Whether a good device can operate normally, safely and effectively is directly related to the installation.
