The Multi-function Servo Tank Gauge provides more information for Loss Control, Safety, Environmental, and Operations than any other tank gauge system ever developed.  It provides and exceeds data needed to meet a host of API Recommended Procedures or Standards for Overfill Protection, Rupture Monitoring (Over pressure & Vacuum), Product Quality (Sampling), Vapor Emissions Monitoring, Leak Detection, Product Stratification Monitoring for In-Tank Blending, Water Settling (Bleeding), etc. thus assuring payback on your investment.

The multi-function servo tank gauge provides more usable data from a single instrument than any tank gauge on the market. It is the most accurate tank gauge for Volume, Mass, average and multi-strata density, water content accurate level, multi-point and average temperature, and vapor pressure. An optional sensor is available for ambient pressure, ambient temperature, ambient density.

Physical Design</p

Physically, the multi-function servo tank gauge is a single stainless steel instrument with a standard diameter of 2” (other custom variations of probe diameter and materials are available.). The multi-function servo tank gauge requires one flange on the top of the tank and installs in sections. The standard configuration requires only two Intrinsically Safe electrical connections; one for power (12VDC) and one for communications (MODBUS RTU via RS 485).  The multi-function servo tank gauge has fewer terminations and potential failure points than other tank gauging systems using multiple instruments with multiple tank openings.

The multi-function servo tank gauge can be installed within or without a gauge well. When installed in a gauge well 6” or larger, there is enough room to perform manual hand lines or sampling.  This allows the verification of all measured parameters for Volume by Hybrid (Level, Temperature, Density, & Water) or Hydrostatic Method (Mass, Density, & Water) from the same physical location and product media.  This enables verification of the gauge calibration and accuracy in comparison to the known reference.

The multi-function servo tank gauge uses an O-ring seal flange at the tank top to allow continuous bottom referencing even if there is any tank bottom or roof movement.  An optional (Manually read or remotely read) TBMI “Tank Bottom and roof Movement Indicator” is also available.

All multi-function servo tank gauge pipe sections and sensor housings are machined and measured to precisely determine the exact location of each sensor. Standard multi-function servo tank gauge sensors are highly accurate absolute pressure transducers with Class A, 100 Ohm Platinum, Four wire RTDs. Optional sensors and combinations are available.

Applications

The design of the multi-function servo tank gauge is highly adaptable, and can be manufactured to meet the needs of multiple applications. The multi-function servo tank gauge has been installed into various tanks worldwide:

• Tank Heights ranging from 8’ (2.43m) to 265’ (80.77m)
• Climates (Tropical, Polar, Dry, Mild, Continental)
• Clean Products (Gasoline, JP, etc.)
• Dirty Products (Crude Oil, Lubricants, etc.)

Tank gauging is essential for the assessment of tank contents, tank inventory control and tank farm management. Portfolio of high-end radar & servo tank gauges help in accurate level gauging for refineries, tank terminals and petrochemical industries. Servo 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.

The current servo level gauging technology 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.

How Does It Work?

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 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.

What Problems Does It Solve?

​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.
