With the continuous development and progress of my country’s industrial industry, the requirements of various units on measuring instruments will become higher and higher, and the adaptability of products will also be further strengthened. In the petroleum, chemical, pharmaceutical and other industries, the stability of measuring instruments has a huge impact on production and operation. The correct use and maintenance of instruments and meters is the key to whether the production cycle can be carried out as planned. Then we are in daily How to use and maintain the magnetic flap level gauge at work? 1. No magnetic material is allowed to approach the magnetic flap level gauge body, and iron wire fixing is forbidden, otherwise it will affect the normal operation of the magnetic flap level gauge;2. When debugging the magnetic flap level gauge, first open the upper lead valve, and then slowly open the lower valve to allow the medium to enter the main duct smoothly (in operation, avoid rapid impact of the medium on the float, causing dramatic fluctuations in the float, and affecting the accuracy of the display. ), observe whether the magnetic red and white ball flips normally, then close the lower lead valve, open the drain valve, and let the liquid level in the main pipe drop. According to this method, operate three times, it is normal, and then it can be put into operation (except for special liquids such as corrosive) ；3. The medium should not contain solid impurities or magnetic substances, so as not to cause jamming of the float;4. The magnetic flap level gauge should clean the main duct from time to time to remove impurities according to the condition of the medium;5. Before use, the small balls below the zero position should be set to red with a correction magnet, and the other balls are set to white;6. If users use heat tracing pipelines by themselves, non-magnetic materials, such as copper tubes, must be used. The heating temperature is determined according to the condition of the medium;7. Open the bottom flange, and install the magnetic float (note: the heavy end has the magnetic end upwards, and it cannot be upside down.);8. For magnetic flap level gauges exceeding a certain length (common type> 3 meters, anti-corrosion type> 2 meters), a middle reinforced flange or ear pan should be added as a fixed support to increase the strength and overcome its own weight;9. The installation of the magnetic flap level gauge must be vertical, and a ball valve should be installed between the magnetic flap level gauge and the container lead pipe for easy maintenance and cleaning;10. The installation position of the magnetic flap level gauge should be avoided or far away from the entrance and exit of the material medium to avoid rapid changes in the local area of the material fluid and affect the accuracy of the liquid level measurement;11. When the magnetic flap level gauge is equipped with remote transmission supporting instruments, it is necessary to ensure that the junction box inlet hole is laid, and the sealing is required to prevent rain, moisture, etc. from invading the remote transmission supporting instruments. The junction box is in It should be covered in time after the overhaul or debugging is completed.
