Green Hydrogen Production Temperature Measurement
Achieve accurate temperature measurement and eliminate leak points with non-intrusive temperature monitoring solutions.
Process Temperature Measurement That Improves Safety and Reduces Costs
Temperature measurement and control is vital to the hydrogen production process, but using traditional thermowells for monitoring temperatures during hydrogen production can be problematic for operators. Traditional thermowells require wake frequency calculations increasing cost and complexity. Additionally, hydrogen particles are extremely small, and thermowell installation creates the potential for multiple leak points. Emerson's Rosemount X-well Technology offers a non-intrusive process temperature measurement solution that is installed without penetrating pipes, provides accurate temperature measurements, and helps reduce overall project costs.
