Muhim texnik afzalliklar
-
High-Density Multi-Point Sensing: The NMT81 can be equipped with up to 24 Resistance Temperature Detectors (RTDs) distributed along its length. This high density allows for a highly accurate temperature profile of the product, regardless of thermal stratification within the tank.
-
Custody Transfer Precision: With a total accuracy of ± 0.032°C (following a 5-point calibration), the NMT81 meets the stringent requirements of international weights and measures standards. This precision ensures that financial transactions based on tank inventory are fair and documented.
-
Integrated Water Bottom Detection: An optional 2-meter capacitance sensor can be integrated into the bottom of the probe. This allows for the continuous, real-time measurement of the water level that naturally accumulates under oil or chemicals, ensuring pure product volume can be calculated accurately.
-
System Synergy: The NMT81 is designed to work seamlessly with the Proservo (NMS8x) and Micropilot (NMR8x) series via the TankSideMonitor NRF81. It functions as a primary data source for advanced tank gauging systems, providing the temperature compensation necessary for radar or servo-based level devices.
-
Operational Reliability: The device employs a software algorithm to process redundant RTDs. If one sensor element fails, the system automatically compensates, significantly reducing maintenance-related downtime and ensuring the “average” calculation remains valid.
-
Corrosion Resistance and Protection: All process-wetted parts are built to resist corrosion from hydrocarbons and chemicals. The housing is both waterproof and dustproof, designed for long-term exposure on top of external floating or fixed-roof tanks.
