MODBUS / BACnet Gateway


Veeder-Root’s MODBUS / BACnet Gateway is an add-on component to TLS family Automatic Tank Gauges. It supports multiple protocols to communicate ATG information to Building Automation Systems. Paired with a Veeder-Root TLS system, the MODBUS / BACnet Gateway relays real-time tank gauge data including tank inventories, sensor performance, liquid alarms, delivery data, and system status.
