The Application of Liquid Level Transmitters in the Petrochemical Industry

The petrochemical industry, as a pillar of the national economy, is always accompanied by harsh working conditions such as high temperature, high pressure, and strong corrosion in its production process. The media are mostly dangerous substances such as crude oil, refined oil, aromatic solvents, and sulfur-containing wastewater. As a core link in the production process control and safety supervision, liquid level measurement is directly related to the stable operation of the equipment, accurate material measurement, environmental compliance, and personnel safety. Any measurement deviation may cause major safety accidents such as tank overflow leakage and fire explosion. The liquid level transmitter designed based on the magnetic float principle produced by Yuanben Company, with its stable and reliable measurement performance, excellent corrosion resistance, and flexible adaptability, has become the ideal choice for liquid level monitoring in the petrochemical industry.-Liquid level transmitters for petrochemical industry

Precise Adaptation to Working Conditions: This liquid level transmitter adopts a modular core structure, consisting of a guide rod with an internal reed switch and a float ball with a magnet. Its working logic fully meets the requirements of the petrochemical industry for the accuracy and continuity of liquid level monitoring. When the liquid level in the storage tank or reactor changes, the float ball with a magnet rises and falls synchronously with the liquid level, driving the reed switch inside the guide rod to close in sequence through magnetic coupling, thereby changing the circuit resistance value. This physical change is processed by the built-in R/I converter and stably outputs a 4 to 20mA standard current signal or a 1 to 5Vdc voltage signal. These two signals have strong anti-interference capabilities and can be transmitted over long distances in the complex electromagnetic environment of petrochemical plants, providing real-time and accurate liquid level data to the central control system. Ultimately, it enables remote display, automatic regulation, and over-limit alarm of the liquid level, eliminating the lag and safety risks of manual inspection from the source.

Corrosion-resistant and durable design: Overcoming the core material challenges in the industry. The strong corrosiveness of petrochemical media is the primary challenge faced by liquid level measurement equipment. Sulfur-containing media, acids, and alkalis can easily erode the contact components of the equipment, leading to a decrease in measurement accuracy or even equipment failure. This liquid level transmitter has been specifically optimized in material selection, with the core components inserted into the liquid all made of SUS304 or 316L stainless steel. Among them, 316L stainless steel, with its excellent resistance to intergranular corrosion and pitting, can effectively resist the erosion of chlorine and sulfur-containing media. It also has good cleanliness and will not contaminate petrochemical products, fully meeting the industry's strict requirements for medium purity. This high-quality material selection ensures the stability and service life of the transmitter under long-term harsh operating conditions, significantly reducing equipment maintenance frequency and replacement costs, and providing a solid guarantee for production continuity.

Flexible customization features: Adapt to diverse application scenarios. The petrochemical production environment is highly diverse, ranging from atmospheric storage tanks, reflux tanks of vacuum distillation columns to high-pressure reactors. The liquid level measurement requirements for different equipment vary significantly. The length of the guide rod needs to match the height of the storage tank, and the installation method needs to be compatible with the equipment interface. Some sites also require an intuitive local display function.

Yuanben liquid level transmitters can precisely customize the length of the guide rod according to the actual needs of customers, perfectly adapting to storage tanks and reaction equipment of different volumes and heights. In terms of installation methods, it offers two mainstream options: threaded and flanged. The flanged interface can be compatible with industry standards, ensuring convenient installation and sealing to prevent medium leakage. At the same time, it supports the on-site installation of an LCD display module, allowing operators to directly read real-time liquid level data, meeting both local inspection and remote control requirements, and significantly improving maintenance and operation efficiency.

Compliance and Safety Empowerment: Facilitating High-Quality Industry Development. The safety and environmental protection regulations in the petrochemical industry are becoming increasingly strict, imposing higher requirements on overfill protection of storage tanks, leakage prevention, and control of volatile organic compound emissions. This float ball level transmitter provides core data support for safe and compliant production through precise liquid level monitoring and stable signal transmission: in crude oil storage areas, it enables accurate inventory calculation, avoiding economic disputes caused by measurement errors; in key devices such as catalytic cracking and hydrocracking, it can monitor liquid level fluctuations in real time and interlock with safety devices such as emergency pressure relief valves to prevent tank overflow and equipment overpressure; in storage processes involving corrosive media, it effectively reduces leakage risks with its corrosion-resistant materials and reliable sealing design, helping enterprises meet environmental protection regulatory requirements.

In the context of the petrochemical industry's pursuit of safe, efficient and compliant development, the reliability and adaptability of liquid level measurement equipment are of vital importance. The Yuanben float ball type liquid level transmitter, with its precise magnetic coupling measurement principle, corrosion-resistant and durable material selection, and flexible and diverse customization features, precisely meets the demanding working conditions of the industry, providing stable guarantees for liquid level monitoring throughout the entire production process.
