KVARTA Control System of Parameters

The system is designed for:
- automatic continuous measurement of environment level and temperature in storage tanks;
- computation (depending on the model variants) of:
- warning about:
- measuring converter unit (MCU);
- base unit (BU);
- PC-based controller;
- cable communication line between MCU and BU;
- uninterruptible power supply (UPS).
- management of process equipment;
- warning alarm;
- extraction of petroleum products;
- storage of petroleum products and liquefied gases;
- transportation of petroleum products and liquefied gases;
- refining of petroleum products;
- storage in tank farms and oil terminals.
The system is comprised of:
Explosion-proof design: 1ExibIIВТ5 for MCU and ExibIIВ for BU (Certificate of Conformity No. ТС RUС-RU.МЕ92.B00408 to requirements of Technical Regulations of the Customs Union ТР ТС 012/2011).
Employment of the same cable line for power supply, control and transmission of probing and return data signals.
Projection and warning alarm for prevention of controlled environment overflow.
Kvarta Control System is manufactured as per technical specifications AGTS.407626.003 TU.
System functions:
monitoring of parameters of petroleum products (petroleum, gasoline, oil) and liquefied gases (propane, butane, ammonia).
