Specification :

It is volumetric positive displacement type, which is used sealed chamber ( drum) with liquid ( water or oil) , therefore, almost all type of gas can be measured without a influence of relative density and viscosity etc. Since this structure has no leakage, it can measure minute flow rate and have high reproducibility.

W-NK type for experiment/ environmental measurement

The measurement drum and case is made of stainless steel as standard specs, it has high durability and anti-corrosion.

W-NT type for a large quantity flow rate

It has been kept customizing for long time, therefore, it has stable performance and high durability.

W-NH type for high pressure gas measurement ( as wet type)

The case is designed for capacity to endure high pressure, therefore, it has high pressure-resistance case and good airtight.

WS for experience/ minute flow rate measurement

It is easy to adjust liquid level semi-automatically by adoption of over-flow system. Using synthetic resign material leads to light-weight and easily portable.
