Why Choose Endress+Hauser FLOWSIC600-XT
Why Choose Endress+Hauser FLOWSIC600-XT
Value Elements
- Extreme Precision
- The FLOWSIC600-XT is certified to OIML R137 Class 0.5, ensuring extreme precision even in challenging or turbulent flow environments.
- Integrated pressure and temperature sensors correct volume calculations in real-time, accounting for expansion and contraction of the meter body.
- Its high-accuracy ultrasonic measurement makes it a strong fit for custody transfer and high-value natural gas measurement applications where small measurement errors can impact revenue.
- The Ultrasonic Advantage
- No moving parts eliminate mechanical wear, reducing downtime and maintenance costs.
- Maintenance-free design simplifies long-term operation.
- Low pressure loss helps support efficient gas movement through transmission pipelines, gate stations, and large industrial natural gas systems.
- Because there are no mechanical parts in the gas stream, the FLOWSIC600-XT maintains stable measurement performance over time without the same wear concerns as turbine or rotary meters.
Comparison vs. Next Best Alternative (NBA)
