High PressHigh Pressure Guide (Supercritical H2S/N2)

[|Industry Challenges]：

In supercritical liquid/gas conditions (such as H2S or N2), the medium is at the critical point of physical state change, making its properties extremely unstable. Minute pressure fluctuations can cause significant measurement drift or even cavitation. More severely, an operating pressure of 25MPa poses a life-and-death test for the instrument's sealing and material strength. Traditional flowmeters are prone to internal stress deformation under high-pressure impact, resulting in complete loss of accuracy.

[COLISEN Solution]：

For this specific application (0.5-10L/min, 25MPa), COLISEN recommends the CMASS008PK High-Pressure Sensor. This model has a design pressure of up to 50MPa, providing a 2x safety margin. Combined with 316L stainless steel measuring tubes, it not only resists H2S corrosion but also maintains zero deformation under high pressure. Paired with the CLS100 transmitter, it delivers a robust gas accuracy output of ±0.5%.

[Manufacturing Excellence]：

COLISEN possesses China's only 8-axis all-electric fully automatic tube bending equipment, ensuring one-time precision shaping of thick-walled high-pressure pipes. Each CMASS008PK undergoes global heat treatment in a high-vacuum brazing furnace to completely eliminate residual welding stress. Combined with the DSP+ARM digital direct-drive core, we can filter out noise generated by high-pressure pulsations in real-time.

[ Value Proposition]：

By accurately matching sensors with 50MPa design pressure, COLISEN helps customers achieve "zero-drift" metering in supercritical experiments, significantly enhancing process safety and data repeatability.
