Software Updates

Keep ahead of increasing security threats with routinely updated operating software. Gilbarco Veeder-Root is also setting the industry standard when it comes to software deployment, including new tools like Centralised Device Manager that manages console software updates across a network.

System Security

Designed to limit system vulnerabilities, the TLS4 series segments security for optimal protection. This includes the use of partitioned Ethernet Ports to separate trusted network from the internet, and the ability to reassign or control the availability of ports.

Custom User Access

Implementing a program for securing user access helps to reduce risks directly on the gauge. Using front panel security, username and password requirements, and predefined or custom user roles to assign permissions, the customer user access features support better data control.

Access your data whenever, wherever.

  •   Clear access to data via a large colour touchscreen
  •   Easy to use, intuitive menu operation
