Liquid level transmitter is a widely used measuring instrument in the field of industrial automation, mainly used to measure the liquid level height of containers such as storage tanks and pipelines. Proper use and maintenance of liquid level transmitters is one of the important measures to ensure safe production. This article will introduce the safe operation and maintenance procedures for liquid level transmitters.

1、 Safety operating procedures for liquid level transmitters

1. Understand the technical parameters and scope of use of liquid level transmitters

Before using the liquid level transmitter, it is necessary to have a detailed understanding of its technical parameters and scope of use to ensure that it can meet the actual working requirements. When selecting a liquid level transmitter, special attention should be paid to its measurement range, accuracy, environmental temperature, and other parameters.

2. Correct installation of liquid level transmitter

The correct installation of liquid level transmitters is an important guarantee for their normal operation and effectiveness. During the installation process, the following principles should be followed:

The liquid level transmitter should be installed around the container and fixed in a stable position to avoid collision and compression from external objects.

The installation position of the liquid level transmitter should avoid being affected by factors such as humidity, high temperature, corrosion, etc.

The pipeline connected to the liquid level transmitter must be placed on a flat surface and ensured to be leak free to avoid damage to the liquid level transmitter.

Before connecting the level transmitter to the pipeline, the interior of the pipeline should be carefully cleaned and purged to avoid impurities contaminating the level transmitter.

3. Correct use of liquid level transmitter

When using a liquid level transmitter, the following precautions should be taken:

When connecting pipelines, the nuts inside the joints should be loosened to avoid thread damage caused by excessive force.

When removing the liquid level transmitter, strictly follow the requirements to avoid damage caused by bending or excessive pressure.

4. Maintenance operation procedures

During the use of the liquid level transmitter, it is also necessary to pay attention to the following maintenance operation procedures:

Regularly check whether the wiring terminals and connections of various components of the liquid level transmitter are loose.

Regularly calibrate the indication and signal output of the liquid level transmitter to ensure its precise operation.

Regularly clean the appearance and internal components of the liquid level transmitter to ensure it is dry and avoid being affected by factors such as corrosion and oxidation.

When the liquid level transmitter is working, it is necessary to activate the pipeline connected to it. Pay attention to the pressure inside the pipeline to avoid safety accidents caused by sudden disconnection of the pipeline.

2、 Maintenance procedures for liquid level transmitters

Proper maintenance of the liquid level transmitter is essential during its use. Below, we will introduce the maintenance procedures for liquid level transmitters.

1. Regularly check the performance of the liquid level transmitter

During the use of the liquid level transmitter, it is necessary to conduct regular inspections to confirm whether its working performance is normal. Specific focus areas include:

Is there any abnormal noise or vibration in the liquid level transmitter.

Is the indication of the liquid level transmitter accurate.

Is the signal output of the liquid level transmitter normal.

Whether the liquid level transmitter has leakage, bubbles, or other phenomena.

2. Regularly replace seals

The liquid level transmitter adopts a sealed structure on the outside to prevent water and dust from entering the interior. It is generally recommended to replace the seal once a year depending on the frequency of use and working environment.

3. Regularly clean the surface of the liquid level transmitter

The surface of the aluminum plated plate needs to be wiped with a soft cloth and cleaned with a cleaning agent to avoid the adverse effects of surface oil stains and dust adhesion.

4. Replace damaged parts

Regularly inspect the components of the liquid level transmitter and replace any parts that are damaged, deformed, or rusted in a timely manner.

3、 Conclusion

Liquid level transmitter is a commonly used measuring tool in industrial production. Proper use and maintenance of liquid level transmitter is an important link to ensure production safety and improve production efficiency. This article summarizes the safety operation and maintenance procedures for liquid level transmitters, hoping to provide some reference and help for everyone's work.
