Quartz tube level gaugeWidely used in the petrochemical industry, mainly due to its high temperature resistance, high pressure resistance, corrosion resistance, and intuitive reliability. The following is an analysis of its specific application and advantages in the petrochemical industry:

1. Typical application scenarios

(1) Tank level monitoring

Medium types: crude oil, refined oil (gasoline, diesel), liquefied gas (LPG, LNG), acid-base solutions (such as sulfuric acid, hydrochloric acid), etc.

Application equipment: atmospheric or high-pressure storage tanks, spherical tanks, horizontal tanks.

Function: Real time display of liquid level height, assisting manual measurement or interlocking with automation systems.

(2) Reactor and Tower

Medium types: high temperature and high pressure reaction solution (such as polymerization reactor), corrosive medium (such as alkali solution in chlor alkali process).

Application equipment: reaction kettle, distillation tower, absorption tower, fractionation tower.

Function: Monitor changes in liquid level during the reaction process to prevent overflow or dry burning.

(3) Pipeline and intermediate tank

Medium types: flammable and explosive liquids (such as benzene and ethylene), high viscosity media (such as heavy oil).

Function: Assist in process control to ensure balanced material transportation.

2. Core advantages

(1) Resistant to extreme working conditions

Temperature: Can withstand -80 ℃ to+450 ℃ (such as liquefied natural gas low-temperature storage tanks or high-temperature cracking units).

Pressure: The pressure resistance can reach 16MPa, suitable for high-pressure reaction environments.

Corrosivity: Quartz glass has excellent corrosion resistance to most acids, bases, and organic solvents such as methanol and acetone.

(2) Safe and reliable

Explosion proof design: pure mechanical structure, no electronic components, suitable for explosive hazardous areas (such as Zone 1/Zone 2).

No leakage risk: using flange or thread sealing to prevent medium leakage (especially for toxic or flammable media).

(3) Intuitive and easy to maintain

Direct visualization: Clear display of liquid level through colored float (red and white dual color), reducing misreading.

Low maintenance: No wear on moving parts, only regular cleaning of quartz tubes is required (additional flushing device is needed for easily crystallized media).
