Overview
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.

- Integrated pressure and temperature measurements for additional information on medium and operating conditions
- Integrated control valve
- Independent control of the valve function through integrated processor unit
-
Multi-parameter measurement and processing of sensor data in one device
- Measurement, monitoring and modelling of device and process parameters
- Diagnostic and alarm information for process optimisation
- Fast, accurate and stable control of flow, pressure and temperature
