Teflon material, acid and alkali resistant graphite liquid level gauge
Its core purpose is to accurately, real-time monitor and display the liquid level of various strong acidic, strong alkaline, or other corrosive media in storage tanks, reactors, pipelines, and other containers. It helps operators grasp the medium volume in real time, ensuring the normal operation of production processes, avoiding overfill or shortage accidents, and laying a foundation for safe production and process optimization.
Based on the communicating vessel principle, the gauge forms a connected structure with the measured container. The corrosive medium enters the gauge’s measuring chamber through the connecting port, and the liquid level in the chamber is consistent with that in the container. The graphite base material with Teflon coating acts as a barrier to isolate the medium from the internal components, preventing corrosion. Meanwhile, the clear scale on the gauge body or the matching electronic sensing component transmits the liquid level information to the control system, realizing visual observation or automatic monitoring of the liquid level.

Compared with ordinary liquid level gauges (such as glass, metal, or plastic types), it has obvious competitive advantages:
-
Superior corrosion resistance: Can withstand almost all strong corrosive media (such as sulfuric acid, hydrochloric acid, nitric acid, sodium hydroxide, etc.), which is incomparable to ordinary metal or plastic gauges;
-
Longue durée de vie: The stable chemical properties of Teflon and graphite ensure that the gauge is not easily damaged by corrosion, greatly reducing the frequency of replacement and maintenance;
-
High measurement accuracy: No material aging or deformation affects the measurement results, maintaining consistent accuracy during long-term use;
-
Low comprehensive cost: Although the initial investment is higher than that of ordinary gauges, the long service life and low maintenance cost bring lower comprehensive use cost;
-
Safe and reliable: The leak-proof design and corrosion-resistant material avoid environmental pollution and safety accidents caused by medium leakage.
