24V DC Positive Displacement Flowmeter Stainless Steel Seal Rotary Flow Meter

The Liquid Seal Isolation Data Is Visually Intuitive With The Liquid Seal Rotary Flow Meter

The liquid-sealed rotary drum flowmeter is a device that precisely measures the volume of gas by rotating a drum (rotary drum) in a liquid seal (usually water or oil), with the measurement data being directly visible.

Advantages:

Extremely high precision, can be used as a standard device: This is its core advantage. Due to the precise geometric volume and the absolute sealing of the liquid seal, its accuracy can reach ±0.2% or even ±0.1%, and it is often used in laboratories to calibrate other gas flowmeters.
Direct measurement of standard volume: The measurement result is directly the gas volume under working conditions, which is very intuitive.
Insensitive to flow fluctuations: As long as the gas can drive the rotating cylinder, it can accurately measure, suitable for measuring pulsating flow.
No external power supply required, and the mechanical structure is reliable.

Typical application scenarios

Calibration and verification of gas flowmeters (core application): metrology institutes, flow laboratories, and calibration workshops of large instrument manufacturers.
Scientific experiments and research: chemistry, environmental, and combustion laboratories in universities and research institutions.
Precision measurement in special industries: historically used for trade settlement of urban gas (replaced by more advanced instruments).

The liquid-sealed rotating drum flowmeter is a "living fossil" and "precision benchmark" in the history of flow measurement technology. It represents the pinnacle of mechanical precision manufacturing and the ultimate pursuit of volume standards.
