Information

High precision servo measurement for liquid level, interface and density

For high accuracy custody transfer measurement in crude oil, gasoline, diesel, petrochemicals and chemicals.

Process connections: Flanges

Temperature: -200 to +200°C (-328 to +392°F)

Pressure: 0 to +6bar (0 to +87psi)

Maximum measuring range: 36m (118ft)

Accuracy: ±0.4mm (±0.02")

International explosion protection and custody transfer certificates, overfill prevention WHG, SIL

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

Simplified installation and trouble-free operations due to easy connection to major DCS systems via open protocols

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