It Has Extremely High Precision And Is Known As The "Laboratory Standard" Wet Gas Meter.
A wet gas meter is a volumetric flowmeter that precisely measures the volume of gas based on the principle of liquid (water or oil) sealing by rotating a drum (rotating cylinder).
Extremely high precision: Based on mechanical geometric volume, the precision can reach ±0.2% to ±0.5%, which is the ceiling of accuracy for gas flow meters and is often used as a standard meter.
Direct measurement of working condition volume: The results are intuitive and no complex conversion is required.
Insensitive to flow changes: Within the range from extremely low to rated flow, the accuracy remains consistent, making it suitable for pulsating flow.
No friction from moving parts: The impeller is driven by buoyancy and floats in the liquid, resulting in minimal wear and a long service life.
No external power supply required: Pure mechanical structure, reliable and safe.
Verification and calibration of gas flowmeters (the core of the core): National/Local Metrology Institutes, third-party calibration laboratories, large-scale instrument manufacturers.
High-precision scientific experiments: Measurement of gas consumption in chemical reactions, respiratory metabolism experiments, environmental monitoring sampling volume measurement.
Historical and educational purposes: As a classic instrument, it demonstrates the principle of volumetric flowmeters; it holds an important position in the history of metrology.
The wet gas meter is a "living legend" in the field of gas measurement. It achieves nearly absolute gas volume measurement through the simplest physical principle (liquid seal displacement) and the most precise mechanical manufacturing.
