1.6 Integrated Tank Gauging System
The Varec 4590 Tank Side Monitor provides integrated communications for sites with multiple
tanks, each with one or more sensors on the tank, such as radar, spot or average temperature,
capacitive probe for water detection and/or pressure sensors. Multiple protocols out of the Tank
Side Monitor guarantee connectivity to nearly any of the existing industry standard tank gauging
protocols. Optional connectivity of analog 4 to 20 mA sensors, digital I/O and analog output
simplify full tank sensor integration. Use of the proven concept of the intrinsically safe HART
bus (HART multidrop) for all on-tank sensors yields extremely low wiring costs, while at the
same time providing maximum safety, reliability and data availability.
