Optimass
Krohne Optimass Coriolis mass flowmeters have been installed by oil company OJSC Ulyanovskneft at two loading stations at the Ulyanovsk oil fields in Russia
The Krohne Optimass instruments are being used in a variety of applications to measure the volume and mass flow of crude oil OJSC Ulyanovskneft operates 24 oil fields at Ulyanovsk with an estimated oil output of 380,000 tons per year

ABM chooses Krohne Optimass 1300 for dosing
ABM, a major supplier of mixing, distillation and fermentation systems, has chosen the Krohne Optimass 1300 Coriolis mass flowmeter for a dosing solution it has supplied to a major UK drinks producer
The company has some of the most advanced oil treatment systems, two of which are installed at oil loading and unloading stations located at Vishenki and Novospasskoe.
The Optimass flowmeters are built into these systems.
These stations ensure that the right amount of stock oil is loaded into tanker cars, accurately measuring the oil by mass and volume.
This is carried out regardless of factors that affect the density, flow and viscosity of the oil, such as ambient temperature and its condition and consistency.
The system is also designed to minimise leaks.
Prior to being loaded onto tanker cars, the raw oil stock is heated to 40C and has an average viscosity of 40 cSt and a density of 850 kg/m.
The Optimass flowmeters simultaneously monitor the temperature and density of the crude oil.
Data from the instrument is transmitted via Modbus to a central control room which allows operators to monitor the loading process effectively.
Users enter the amount of oil that needs to be transferred into the tanker cars and the system ensures that the precise amount is loaded.
Operators can perform diagnostic inline checks on the flowmeter to ensure the system is working correctly.
This can include, for example, analysis of the quality of measurement.
The oil treatment systems were installed as part of a major investment to improve environmental performance at the plant.
Krohne developed the world's first Coriolis mass flowmeter with a single, straight-tube design.
The Optimass was launched in 2002 incorporating this innovative development.
It also includes the Krohne patented AST (Adaptive Sensor Technology) design, which ensures stable operation under varying process conditions without special installation requirements.
