Instrumentation, no matter how good its quality, is inseparable from continuous maintenance and maintenance. Only in this way can it be more precise in operation and maximize the service life. Today, Yijia Instrument will share with you the daily maintenance and maintenance experience of electromagnetic flowmeter. Garden lights are outdoor lighting fixtures that are specifically designed to illuminate gardens, pathways, and other outdoor spaces. They come in a variety of styles and designs, including post lights, spotlights, wall-mounted lights, and hanging lanterns. Garden lights can be powered by electricity or solar energy, and they typically feature energy-efficient LED bulbs. They are an essential element of outdoor decor, providing both functional illumination and aesthetic appeal. Garden lights can be used to highlight specific features of a garden, create a warm and welcoming atmosphere, and enhance the overall beauty of an outdoor space.

The use of electromagnetic flowmeters is very extensive, saying that it is the innocent king of the flowmeter field, and it is not an exaggeration. Of course, the medium that cannot measure the dielectric constant is too short, which is also determined by the principle of its working measurement and cannot be exceeded.
First of all, the most intuitive to check the external situation, such as whether the grounding system is in good contact, whether the sealing part is complete, whether there is dripping or vibration in the pipe installation part, whether the connecting bolt and the mounting bracket are loose.
Second, the maintenance and maintenance of the electrode part. There are a lot of references on the Internet for you to check, but this article will be talked about once again and make some additional explanations. 1. Calibration of the electromagnetic flowmeter and cleaning of the electrode. The calibration must use the standard PH value liquid. After the calibration is completed, the electrode should be cleaned with distilled water. After the first cleaning, the electrode to be tested must be cleaned again. Many people tend to ignore this step, in fact, this is also very important. 2. When cleaning or disassembling the electromagnetic flowmeter, it is necessary to protect the electrode part. Collision and damage will affect other uses. 3, electromagnetic flowmeter also need to protect the electrode when not in use, install the electrode sleeve, and keep the bulb moist, here must use a saturated solution, remember not to be placed in distilled water for soaking. 4. In order to maintain the measurement accuracy of the electromagnetic flowmeter, the electrode is the key. Keeping the electrode clean is an important condition to extend its life and maintain measurement accuracy.
Finally, the converter part, this is also the key to the electromagnetic flowmeter, but for technical reasons, this part of the fault is generally unable to be used by the unit, so as long as the converter is faulty, it is repaired by the manufacturer. of.
