Metering skid — Fuel / Base Oil
For fuel oil, base oil, lube oil and other viscous or temperature-sensitive products — the same metering objective as LNS-MS-LH, but a different hydraulic problem.
Product overview · LNS-MS-FO
The LineSig LNS-MS-FO is specially engineered for tanker loading of medium- to high-viscosity liquid products such as fuel oils, base oils and finished lubricating oils. Unlike conventional light-hydrocarbon metering, these applications require careful consideration of viscosity, operating temperature, pressure drop and heating requirements.
Coriolis mass flow measurement remains the preferred LineSig approach wherever technically suitable; a positive-displacement meter may be evaluated as an alternative where Coriolis pressure drop becomes excessive because of viscosity, line size or very high capacity.
For high-viscosity products, the skid is sized based not only on normal operating conditions but on the highest credible viscosity at the lowest operating temperature. The design may therefore include steam, thermal-oil or electric tracing, insulation, heated filters, jacketed equipment, recirculation and warm-up lines. Typical products: fuel oil, heavy fuel oil, furnace oil, base oil SN150/SN500, bright stock, lube base stocks, finished lubricants and other high-viscosity petroleum products.
Design
Metering selection: PD metering is not the default LineSig position. Coriolis remains preferred where technically suitable; PD is retained as an engineering alternative for duties where line size, viscosity, pressure drop or project philosophy justify it.
