Product Introduction
The VEGA VEGAMET 391 is a controller and display instrument for processing signals from a compatible 4–20 mA/HART sensor. It scales and displays measured values, provides switching signals for external equipment, and supports monitoring and control tasks in industrial applications.
Key Features
- 4–20 mA/HART Sensor Input: Powers and processes a compatible connected sensor.
- Integrated Pump Management: Supports pump switching and balanced pump utilization.
- Flow Measurement and Totalization: Provides functions for flow calculation and cumulative volume monitoring.
- Web Server: Enables network integration and remote access to measurement data.
- Multiple Outputs: Includes a configurable 0/4–20 mA current output and up to six relay outputs, depending on version.
- Flexible Configuration: Supports on-site adjustment and PACTware/DTM configuration software.
- SIL 2 Option: Available with applicable safety-related configurations.
Applications
- Water and Wastewater Treatment: Monitoring levels and managing pumps in treatment facilities.
- Pumping Stations: Controlling pump switching based on measured levels or configured limits.
- Flow Monitoring: Calculating and totalizing flow for water management systems.
- Tank and Reservoir Monitoring: Displaying level measurements from compatible sensors.
- Industrial Process Control: Processing pressure or level signals and transmitting outputs to external control systems.
- Remote Inventory Monitoring: Providing measurement data for remote monitoring and inventory management applications.
Technical Highlights and Selection Considerations
The VEGAMET 391 combines sensor signal processing, local display, relay control, and network connectivity in one controller. It is particularly useful where pump management and flow totalization are required alongside level monitoring.
Before ordering, confirm the sensor output, required relay functions, current output range, Ethernet or RS232 interface, supply voltage, mounting arrangement, and required approvals. Ethernet and RS232 are alternative interface options, and available outputs vary by configuration.
