Varec 8315 Series manual Features

8300 Overview

1 Overview

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.
