FOCUS-1 is the first smart meter valve specifically developed for the process industry 4.0. This multifunctional smart flow control instrument – developed by FOCUS-ON, a SAMSON and KROHNE company – combines sensors, actuator and control functionality in one device. By measuring flow, pressure and temperature simultaneously and regulating its valve function independently, all specified set points for control tasks such as pressure, flow or even external control variables can be accurately and reliably achieved. This makes FOCUS-1 the ideal smart control unit for processes that need to be controlled autonomously. It is equally suitable for greenfield projects as well as a drop-in replacement of conventional valves in existing brownfield applications.
