Honeywell Enraf Servo 954

Honeywell Enraf Servo 954

The Honeywell Enraf Servo 954 is a high-accuracy automatic tank gauge designed to measure liquid level, interface, temperature, density, and water-bottom in storage tanks. With advanced electronics, robust construction, and SIL-ready safety features, it delivers reliable performance for inventory control and overfill prevention in refineries, terminals, and industrial tank farms.

Features

  • Multi-parameter measurement: Level, interface, temperature, density, and water-bottom in one device.

  • High accuracy & reliability for custody transfer and critical operations.

  • SIL-ready safety features to support overfill prevention.

  • Modular, upgrade-friendly design for easy migration from older gauges.

  • Built for harsh environments which are ideal for refineries, terminals & petrochemical facilities.

  • Advanced diagnostics for reduced downtime and lower maintenance costs.
