Description
Endress+Hauser NMS81: Precision Tank Gauging Solution
The Endress+Hauser NMS81 is a precision tank gauging solution designed for high accuracy liquid level measurement in custody transfer and inventory control. It boasts NMi- and PTB-approvals and meets the strict requirements according to OIML R85 and API 3.1B. Optimized for total cost saving and safe operation, the NMS81 fulfills the demands of tank inventory management and loss control.
High Accuracy for Crude Oil Measurement
The NMS81 excels in high accuracy for crude oil measurement, making it ideal for custody transfer applications involving crude oil, gasoline, diesel, petrochemicals, and chemicals. Its precision ensures reliable data for inventory management and loss control, critical in financial transactions and operational efficiency within these industries. The device delivers stable and accurate measurements, ensuring optimum performance in demanding environments.
Superior Corrosion Resistance in Sour Applications
One key benefit of the NMS81 is its superior corrosion resistance in sour applications. Constructed with 316L materials, it offers excellent compatibility with sour applications such as crude oil. This ensures a longer lifespan and reliable performance even when exposed to corrosive substances, reducing maintenance costs and enhancing overall system reliability.
Ideal for LNG/LPG Applications
The NMS81 is ideally suited for ideal for LNG/LPG applications, demonstrating robust performance without influence from DC value or Boil Off Gas. Its design enables accurate and consistent measurements in cryogenic environments, crucial for safe and efficient storage and transfer of liquefied gases. This specialized application makes it invaluable for the LNG/LPG industries.
SIL3 Compliance, Enhanced Safety Standards
The Endress+Hauser NMS81 provides SIL3 compliance, enhanced safety standards, developed according to IEC 61508 up to SIL3 (in homogeneous redundancy), ensuring a high level of safety. International explosion protection and custody transfer certificates, along with overfill prevention WHG, further guarantee operational safety and compliance with industry regulations. This makes the NMS81 a secure choice for hazardous environments.
Measures Interfaces Between Multiple Liquid Layers
The NMS81 accurately measures interfaces between multiple liquid layers. It can measure interfaces between up to three liquid layers, the tank bottom, spot density, and profile densities. This capability is essential in refining and chemical processing, providing detailed information for quality control and process optimization, enabling precise monitoring and separation of various liquid products.
