Connect tank gauge data to building automation systems

The MODBUS / BACnet Gateway is an added component used to connect Veeder-Root automatic tank gauge consoles to building automation systems.

The Veeder-Root MODBUS / BACnet Gateway is an add-on component for Veeder-Root TLS Automatic Tank Gauges (ATG). It supports multiple protocols to communicate ATG information to building automation systems. Paired with a Veeder-Root tank monitoring system, the MODBUS / BACnet Gateway relays real-time tank gauge data including tank inventories, sensor performance, liquid alarms, delivery data, and system status.
