Level gauges are commonly used in industrial production to measure the height of a liquid or the volume of a liquid in a container. The daily inspection of liquid level meter is very important to ensure the accuracy and reliability of the liquid level meter, as well as timely detection and resolution of potential failure problems. In this article, we will introduce the contents and methods of daily inspection of liquid level meter.

I. Appearance check

Appearance check of the level meter is mainly to check whether the external parts of the level meter are intact, including the level meter body, connecting pipelines, valves and sensors. First of all, check whether there is obvious damage or breakage of the level meter body, such as cracks, scratches, etc.. Secondly, check the tightness of the connecting piping to ensure that there is no air leakage at the connection. Finally, check whether the valves and sensors are working properly, such as whether the opening and closing are flexible and whether there is abnormal sound, etc.

II. liquid level measurement

The core function of the liquid level meter is to measure the height of the liquid or the volume of the liquid in the container. Therefore one of the focuses of daily inspection of the liquid level meter is to carry out liquid level measurement. First, check whether the measurement range of the level meter matches the actual demand, such as whether it can measure the highest and lowest level of the liquid. Secondly, carry out level measurements, observe whether the measurement results are accurate and stable and compare them with the actual liquid level.

III. Power-on inspection

The level meter usually needs to be connected to the power supply to work normally, therefore, the power-on check is one of the important parts of the daily check of the level meter. First of all, check whether the power cord is intact and free from breakage and damage. Secondly, turn on the power and observe whether the level meter starts normally and whether the display shows the level information normally. At the same time, you also need to check whether the alarm system of the liquid level meter is working normally, such as alarm indicator, sound alarm and so on whether it can send out alarm signals normally.

IV. Cleaning and maintenance

The daily inspection of the liquid level meter also includes cleaning and maintenance work. First, the external surface of the level meter is cleaned regularly to ensure that there is no dust and debris attached. Second, clean the measuring parts of the level meter to remove dirt and deposits that may affect measurement accuracy. When cleaning, care should be taken to use appropriate cleaning agents and tools to avoid damage to the level meter. In addition, regularly check the sealing performance of the level meter, such as whether the waterproof seal is intact, to ensure the normal operation of the level meter in a humid environment.

V. Record and analyze

The last step in the daily inspection of the level meter is to record and analyze the inspection results. The date, time, inspection content and results of each inspection should be recorded for subsequent analysis and comparison. At the same time, you can also compare and analyze the results of multiple inspections to understand the level meter's working status and performance changes, and timely detection and resolution of potential faults.

The daily inspection of liquid level meter includes appearance inspection, liquid level measurement, power-on inspection, cleaning and maintenance, as well as recording and analysis. Through regular daily inspection of the liquid level meter, it can ensure the normal operation and accurate measurement of the liquid level meter, and improve the production efficiency and product quality. At the same time, it can also timely find and solve the problem of liquid level meter failure, to avoid production interruption or other safety hazards caused by failure. Therefore, the daily inspection of liquid level meter is very important and should be given enough attention and concern.
