Field of application

The intelligent tank gauge Proservo NMS81 is designed for high accuracy liquid level measurement in custody transfer and inventory control applications with NMi- and PTB-approvals. It meets the relevant requirements according to OIML R85 and API 3.1B. It fulfills the exact demands of tank inventory management and loss control and is optimized in regards of total cost saving and safe operation.

Benefits

Hardware and software developed according to IEC 61508 up to SIL3 (in homogeneous redundancy) for high level of safety

Maximum reliability through accuracy up to ±0.4mm (± 0.02″)
Developed according to international metrology recommendations such as OIML R85 and API MPMS

Local and country-specific certifications like NMi or PTB for custody transfer applications

Superior corrosion resistance with 316L materials in the process compatible with sour applications such as crude oil

Measurement of interfaces between up to three liquid layers, tank bottom, spot, and profile densities

Best fit for LNG/LPG applications without influence of dc value or Boil Off Gas
