Less On-tank Activities

The 8650 Operator Interface Terminal (OIT) allows you to display liquid inventory data in areas away from the main control room, such as a remote pumphouse. Users can quickly and easily review the contents of up to 10 connected tanks without going into the tank farm.


Extend Your Existing Equipment

Acting as a MODBUS master, the 8650 OIT polls data from any connected MODBUS slave device, such as an 8130 RTU or 8300 TGI, to receive tank data.


Configuration and Programming

Each 8650 OIT must be configured for the specific application. All programming and configuration is performed by Varec’s engineering services.
