• Filters for trapping mechanical solids can be placed at the inlet measuring lines, in case their placement on ML

Quality measurement unit – is a part of the metering system designed for placing of the equipment for the quality parameters of the measured product determination. QMU is made either as a complete subassembly and delivered separately to the Customer, or as a completely assembled metering system.

Structurally QMU manufactured by «GKS» RPE can be made in three versions:

• open version on a separate frame for placement in the existing facilities;
• close version, enclosed in a block-box;
• combined version — QMU is placed on one frame with MLU and can be both of open and closed design. Depending on the size of the accommodated equipment QMU manufactured by GKS is placed on one or more frames, regardless of the open or close design. Functionally QMU are applicable to the metering systems of liquid and gaseous media, if it is necessary to determine their quality parameters

Depending on the application in the respective systems QMU is differentiated by composition of the accommodated equipment:

• Metering systems of oil and petrochemical products

Manufacturing of process rooms for various purposes occupies a significant sector in overall production of «GKS», RPE; and special production capacities are being reserved for their assembly. Process rooms are made both by the design documentation of our own design, as well as on the basis of a design documentation set.

Functionally process rooms can be divided into the following types, depending on the equipment located therein:

• for equipment being directly a part of the metering systems (FU, MLU, QMU, AGMU et al.);
• for process equipment (pumps, dosing skids, et al.);
• for equipment of the middle and upper level of management systems (panels and cabinets, automated work place of operators and dispatchers);
• the laboratory equipment.

Process rooms can be manufactured and delivered to the customer both as a separate subassembly, and fully supplied with technological equipment and life support system. Structurally technological chambers can be assembled on one or more frames placing the supporting structure, covered with non-combustible sandwich panels or profiled sheet with non-combustible insulation. The process rooms are provided, if necessary, with easy detachable design elements.

Process rooms provide the following subsystems to ensure a comfortable and safe operation of the equipment:

• Heating (electric or water), lighting and air conditioning;
• Ventilation inlet and exhaust (determined by the requirements of the design documentation);
• Devices of gas contamination control subsystem;
• Devices of fire detection and fire fighting subsystem (if necessary);
