What Veeder Root Is
Veeder Root is a serial protocol used by fuel and liquid tank monitoring systems, primarily the TLS-3XX console series (TLS-300, TLS-350, TLS-450). These systems monitor tank levels, leak detection, and inventory management at fuel stations and industrial facilities.
In building automation, Veeder Root data is commonly bridged to BACnet or Modbus via a gateway for integration with building management systems.
TLS Console Models
| Model | Era | Interface |
|---|---|---|
| TLS-300 | Legacy | RS-232 serial |
| TLS-350 | Current | RS-232 serial |
| TLS-450 | Current | RS-232 serial + Ethernet |
Communication
Veeder Root uses a proprietary serial protocol over RS-232 at 9600 baud. The gateway acts as a serial client, polling the TLS console for tank data.
[!NOTE] Veeder Root is RS-232 (point-to-point), not RS-485. This is a direct serial connection between the gateway and the TLS console — no multidrop bus.
Common Integration Targets
| Destination Protocol | Use Case |
|---|---|
| BACnet/IP | Tank levels visible in BMS |
| Modbus TCP | Tank data to SCADA systems |
| EtherNet/IP | Tank data to PLC-based systems |
Chipkin Products
The QuickServer gateway (model CAS-2700-02B in legacy references) is the standard product for Veeder Root integration.
