Supervisory Control Cabinets
Complete solution for process control
- Provides control of the metering system, including validation of field instrumentation
- Installed in a safe area, typically in a control room or dedicated building
- Supplied in combination with new metering systems, or for an upgrade to existing systems
Typical metering systems can have an impressive metering skid with piping, instrumentation and valves. The brain of the metering system is however the supervisory control system that is usually installed in the safe area control room. Metering control cabinets include items such as flow computers, Supervisory PCs, PLCs, UPS systems, barriers, switches and fuses. For large installations all equipment in the metering control cabinet can be installed in a fully redundant mode, with flow computers in standby or hot-standby.
KROHNE supplies supervisory control cabinets as a major part of the delivery of a new flow metering system or for upgrades to existing systems where the metering control cabinet would be connected to existing field instrumentation. The KROHNE expertise covers the entire design and manufacturing process. It is starting with a functional design specification, through detailed design, manufacturing and testing, up to commissioning in the field and training of the operators.
Combining the metering control cabinet with KROHNE instrumentation gives a seamless integration. Many systems have also been supplied that communicate with 3rd party instrumentation. After installation, KROHNE metering systems are supported by one of the local offices or agents that are available in over 100 countries.
