Vegamet 391 Signal Conditioning & Display
Brand: VEGAThe VEGAMET 391 signal conditioning instrument powers the connected 4 to 20 mA/HART sensor, processes and displays the measured values.
The VEGAMET 391 is ideal for simple control tasks in level, gauge and process pressure measurement as well as inventory management (VMI) and remote enquiry.
Comprehensive adjustment functions allow individual adaptations to the respective application.
In water/wastewater management, the instrument stands out with special functions such as pump switching, flow volume measurement, tendency functions and totalizer.
Features- Equal Use of all Pumps Through Integrated Pump Management
- Completely Integrated Functional Unit for Flow Volume Measurement
- Simple Integration into the Intranet/Extranet via Integrated Web Server
