Varec recommends a radar (non-contact) technology solution for storage tanks containing viscous products, such as crude, heavy fuel , bunker fuel and other residual fuel oils if a level only measurement is required. If multiple variables are required for inventory management, such as density or water interface, then a servo technology solution is recommended. The other major technologies – hybrid, float & tape and hydrostatic (in order of preference), are also suitable for measurement of middle distillates.
For extremely viscous products, such as asphalt and tar, Varec recommends a non-contact measurement solution, such as radar technology or hydrostatic measurement with heat traced nozzles.
