JOWA - Vanguard IV Level Gauging System

The industry trend of integrating onboard instrumentation systems requires a streamlined approach to tank gauging. JOWA USA has responded to this demand with the Vanguard Level Gauging System, a simple, low cost solution that delivers high performance. The Vanguard System provides the critical link between JOWA USA’s reliable resistancetape level sensors and the centralized control system aboard any vessel type, including tankers, container vessels, gas carriers and FPSO’s.

The Vanguard Level Gauging System sends tank level, temperature, volume, inert gas pressure and draft data via an RS232 / 485 interface to any shipboard control system. This direct serial data communication provides a cost advantage over traditional analog systems. Vanguard delivers more accuracy than traditional ballast, fuel, and draft gauging methods, resulting in better operational control and more efficient vessel management.
