High Pressure Coriolis Flow Meters
High-Pressure Nitrogen Metering: COLISEN DN25 Wide U-Tube Sensor, a 45MPa Robust Performer.
Description
| Industry Challenges]
Nitrogen under a high pressure of 45MPa exhibits compressibility and speed-of-sound changes that pose significant physical interference to sensors. In high-flow conditions (300-1500Nm³/h), traditional differential pressure or vortex flowmeters are not only low in accuracy but their materials are also prone to fatigue or connection leakage under long-term high-pressure gas flow impact.
| COLISEN Solution]:
COLISEN recommends the DN25 Wide U-Tube High-Pressure Flowmeter. The wide U-shaped structure possesses natural low flow resistance and high anti-vibration characteristics. Adopting a remote installation, field layout is flexible, and the 316L corrosion-resistant measuring tubes easily lock in the 45MPa rated high pressure. The ±0.5% gas accuracy ensures that the error in high-flow nitrogen metering is almost negligible.
| Manufacturing Excellence]:
The sensor utilizes thickened 316L material and is shaped once via 8-axis all-electric tube bender to minimize stress to the greatest extent. Each DN25 undergoes extreme stability calibration in our High-voltage testing system, combined with the DSP+ARM digital direct-drive core, providing instantaneous feedback on flow changes to meet the precise metering of industrial gases.
| Value Proposition]:
Make high-flow high-pressure nitrogen metering transparent and controllable. The robust 45MPa performance significantly enhances on-site industrial safety, and the ±0.5% accuracy provides a solid basis for enterprise energy management.
