Tank gauging is essential for the assessment of tank contents, tank inventory control and tank farm management. Honeywell Enraf’s portfolio of high-end radar & servo tank gauges help in accurate level gauging for refineries, tank terminals and petrochemical industries. Honeywell Enraf tank gauges are suitable for custody transfer as well as inventory control and are designed to be used in SIL-2/SIL-3 loops to prevent spillage.
Honeywell Enraf introduced automatic servo level gauging technology in the 1950s, and soon after introduced the first automatic level gauge for bulk liquid storage tanks.
The current servo level gauging technology from Honeywell Enraf includes the Advanced Tank Gauge (ATG) and the Xmitting Tank Gauge (XTG). The ATG and XTG series microprocessor-controlled servo gauges are compact and need only a 2″ mounting flange. The servo level gauges can easily be integrated with existing SmartRadar, hydrostatic or hybrid gauging installations.
Advanced Tank Gauge (ATG)
Designed for measuring all kinds of liquids in any type of storage tank, the series 854 ATG Servo Gauge is a reliable, versatile and accurate automatic tank gauge with minimal moving parts. The multi-functional instrument is modularly constructed. The option slot for additional features allows the connection of temperature measuring elements for spot and average product temperature, as well as product temperature profiles.
Xmitting Tank Gauge (XTG)
The 854 XTG Servo Gauge is a superior alternative to mechanical float and tape gauges or other low-cost level measuring devices. The standard Honeywell Enraf field-proven two-wire correction of tank deformation, roof movement, drum deviation, wire weight and displacer fieldbus is utilized for connection to remote indicators, tank inventory systems and host systems.
The Servo 854 is equipped with a Servo Auto Test feature which increases its safety, integrity and diagnostic coverage; enabling the servo level gauge to be used in overfill protection loops to prevent spillage. The increased diagnostics detect failures inside the level gauge or in the application and report this to higher level systems for further action. Additionally, the safety proof-test interval can be extended to 5 years, significantly bringing down operational costs.
The Enraf Servo Gauge 854 Automatic Tank Gauge (ATG) has become an industry standard all over the world. The gauge is multi-functional: besides liquid level, it integrates density and (free) water interface level measurement with the highest accuracy available in the marketplace. Reliable, versatile and accurate, it meets all international standards, and also can be used in overfill protection loops to prevent spillage. Together with a design featuring minimum moving parts and a modular construction for easy maintenance, it helps users drive down operational costs.
Honeywell offers the Enraf Servo Gauge 854 XTG as an alternative to mechanical float and tape gauges or other low-cost level measuring devices with superior servo gauge technology. The servo gauge offers the proven accuracies and performance of the Advanced Technology Gauge (854 ATG).
