Introduction

Liquid-filled pressure gauges are essential instruments used in various industries to measure pressure in systems and ensure their optimal performance. However, when these gauges begin to leak, it can pose significant risks to operations and safety. This article delves into the reasons why a liquid-filled pressure gauge might leak and provides solutions, including innovative measures from Guanshan Instruments company.

Common Causes of Leakage in Liquid-Filled Pressure Gauges

Several factors can lead to the leakage of liquid-filled pressure gauges. These include:

Improper Installation

Incorrect installation is a primary cause of leaks. Ensuring that the gauge is properly mounted using the correct torque specifications and gaskets can prevent leaks. The recommended torque range is typically between 15-25 Nm depending on the gauge size and model.

Thermal Expansion

Temperature fluctuations can cause the liquid inside the gauge to expand or contract, stressing seals and causing leaks. Ideally, gauges should operate within a temperature range of -20°C to 60°C to prevent these issues.

Seal Degradation

Over time, the seals used in the gauge can degrade due to exposure to environmental factors, leading to leakage. Seal materials should be compatible with the process fluid and operating environment.

Vibration and Physical Damage

Excessive vibration or accidental impacts can compromise the integrity of the gauge, leading to leaks. Installation in environments with high mechanical stress should include vibration dampeners.

Importance of Addressing Leaks Promptly

Ignoring a leaking pressure gauge can have serious implications, including erroneous pressure readings, system inefficiencies, and potential safety hazards. Regular maintenance and timely repair or replacement of damaged gauges are crucial.
