8300 Overview
1Overview
The TankGate (83x series) unit acts as a tank gauge interface for data acquisition and host
gateway for tank farm, pipeline or refinery applications. Options are available for
interfacing to nearly any brand of tank gauge equipment or technologies, making it
possible to integrate float and tape transmitters, HTG, servo, magnetostrictive and radar
gauges.
Each TankGate Unit has a built-in motherboard and communications module based on
the local field protocol or tank gauging instrumentation requirements. The motherboard
contains a serial data link to enable communication to a host PC, PLC, or DCS..
Each intelligent module contains its own processor for fast and reliable field data
scanning. In-built compatibility of every module makes configuration of the internal
TankGate (83x series) database simple and straightforward.
