Teflon float level indicator for acid and alkali solutions
Purpose & Function
Purpose
The primary purpose of this device is to provide real-time, continuous monitoring of liquid levels in tanks, vessels, or pipelines containing acid or alkali solutions. It enables operators to precisely grasp the liquid volume, prevent overfilling (which may cause leakage of corrosive media and environmental pollution) and underfilling (which may lead to equipment dry-running and production interruptions), and support the automation and intelligent management of industrial processes.
Function
The Teflon Float Level Indicator operates based on the principle of buoyancy. The Teflon-coated float is placed inside the measured container and floats on the surface of the acid or alkali solution. As the liquid level rises or falls, the float moves synchronously. This mechanical movement is transmitted to the indicator (such as a pointer, digital display, or electrical signal output module) through a connecting mechanism (e.g., a rod or cable). Subsequently, the liquid level information is converted into a readable signal (mechanical indication or electrical signal) for on-site observation by operators or remote monitoring by the control system. In addition, it can be equipped with alarm devices to trigger alerts when the liquid level reaches preset upper or lower limits, further ensuring operational safety.
-
Exceptional Chemical Resistance: The float and key contact parts are made of or coated with Teflon, which exhibits excellent resistance to almost all strong acids (such as sulfuric acid, hydrochloric acid, nitric acid) and strong alkalis (such as sodium hydroxide, potassium hydroxide). It does not react with corrosive media, ensuring long-term stable operation in harsh environments.
-
High Measurement Accuracy: The buoyancy of the Teflon float is stable, and the transmission mechanism is precisely designed, enabling measurement accuracy of up to ±1mm (depending on the model). It can provide reliable level data even in dynamic liquid environments.
-
Wide Temperature Adaptability: Teflon has a high temperature resistance range (from -200°C to +260°C), allowing the indicator to work normally in both low-temperature and high-temperature acid-alkali solution systems without performance degradation.
-
Simple Structure & Easy Installation: The device adopts a modular design with fewer moving parts. It can be installed in ways such as top-mounted, side-mounted, or flange-mounted, adapting to different container structures and installation requirements. No complex debugging is required after installation.
-
Low Maintenance Cost: Due to the excellent corrosion resistance and wear resistance of Teflon, the float and contact parts have a long service life. The device is less prone to failure, requiring only regular inspection (e.g., checking the float for damage, the transmission mechanism for jamming) and minimal maintenance work.
-
Superior Corrosion Resistance Compared to Conventional Indicators: Unlike level indicators made of metal (e.g., acier inoxydable) or ordinary plastics, which are easily corroded by strong acids and alkalis, the Teflon float level indicator can maintain structural integrity and measurement performance in extreme corrosive environments, significantly reducing the frequency of equipment replacement.
-
High Operational Reliability: The simple mechanical structure reduces the risk of failure caused by complex electronic components (which are easily damaged by corrosive vapors). It can work stably for a long time even in harsh industrial environments with high humidity, strong corrosive vapors, or large temperature fluctuations.
-
Strong Compatibility with Various Acid-Alkali Solutions: It is suitable for measuring almost all concentrations of acid and alkali solutions, including concentrated sulfuric acid, concentrated hydrochloric acid, concentrated nitric acid, and high-concentration sodium hydroxide solutions. It has a wide range of applications and does not require customization for different media types.
-
Cost-Effective in the Long Run: Although the initial purchase cost may be higher than that of ordinary level indicators, the long service life, low maintenance cost, and reduced production losses caused by accurate level monitoring make it more cost-effective in the long-term operation of corrosive process systems.
-
Safe & Environmentally Friendly: By accurately monitoring the liquid level and preventing the leakage of acid and alkali solutions, it avoids environmental pollution and safety accidents (such as burns to personnel caused by corrosive media leakage), complying with industrial safety and environmental protection standards.
The Teflon Float Level Indicator is widely used in various industrial fields involving acid and alkali solutions, including but not limited to:
-
Chemical Industry: Level measurement of acid-alkali storage tanks (e.g., sulfuric acid storage tanks, sodium hydroxide solution tanks), reaction kettles (e.g., neutralization reaction kettles), and pipelines in chemical production processes.
-
Electroplating Industry: Monitoring of the level of electroplating solutions (which often contain acidic or alkaline components) in electroplating tanks to ensure stable electroplating quality.
-
Pharmaceutical Industry: Level measurement of acid-alkali reagents used in drug synthesis processes, as well as cleaning solutions (acidic or alkaline) for pharmaceutical equipment.
-
Water Treatment Industry: Level monitoring of acid-alkali storage tanks in water purification and sewage treatment processes (e.g., acid dosing tanks for pH adjustment, alkali dosing tanks).
-
Metallurgical Industry: Level measurement of corrosive solutions (such as pickling solutions, alkali washing solutions) used in metal pickling, alkali washing, and other surface treatment processes.
-
Laboratories & Research Institutions: Level monitoring of small-volume acid-alkali solution containers in experimental processes to ensure the accuracy and safety of experiments.
