The oil quality measurement and control system
The oil quality measurement and control system (QMCS) is designed for automatic operational measurement of the mass (volume) of oil; determination of its qualitative characteristics (density, moisture content, pressure, temperature); oil sampling; transfer of information to the operator's workstation.
QMCS is a part of oil treatment units (OTU), pumping stations or other surface installations of oil and gas producing enterprises

Part of the equipment
The QMCS includes the following equipment:
- node of input filters;
- unit for measuring the amount of oil with flow meters (volume or mass);
- at least two measuring lines (one is a backup and verification line, the second is a working line, or three separate lines;
- block of quality control and sampling;
- drainage system from pipelines;
- block box or base frame;
- connection points for pipe piston calibration units (TP9) and devices for determining the residual gas content (RGC)
- control and measuring devices.
Block-boxes are equipped with heating, ventilation, gas control and fire alarm sensors.
Upon separate request, the QMCS is completed with a specialized device for processing data from the primary transducers of flow, humidity, temperature, and pressure installed in the QMCS.
Below is the nomenclature of the QMCS.
