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.
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.
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.)
