Ưu điểm kỹ thuật quan trọng
-
Multivariable Measurement: The E 100 measures both volume flow and temperature ($150$ °C max) simultaneously. This allows for the calculation of mass flow or heat energy within the device, reducing the number of process penetrations and lowering the total cost of ownership for utility monitoring.
-
High Turndown Ratio ($200:1$): Boilers and utility systems often experience significant seasonal or operational load changes. The massive turndown ratio ensures that the device remains accurate during low-flow standby periods as well as during peak demand.
-
Conductivity Independence: Unlike electromagnetic flowmeters, the ultrasonic transit-time principle is completely independent of the liquid’s conductivity. This is essential for demineralized water and high-purity condensate, which have zero or near-zero conductivity.
-
Heartbeat Technology: This integrated suite allows for continuous self-monitoring and traceable verification of the device’s health. By providing documented proof of sensor performance without process interruption, it allows plants to safely extend recalibration cycles.
-
Integrated Web Server: The device can be accessed directly via a standard web browser through its service interface. This enables technicians to perform commissioning, configuration, and diagnostics without needing proprietary software or specialized handheld terminals.
-
Robust Stainless Steel Design: To withstand the humid and often corrosive atmosphere of boiler rooms, the entire meter housing is constructed from stainless steel. This ensures long-term external durability alongside its internal sensor stability.
