MTG “Multi-function Tank Gauge” Technology (Patented)
The MTG “Multi-function Tank Gauge” provides the most accurate data on the product in your tank. It is the most accurate gauge for Volume, Mass, Temperature, Density, Water, and Level within the shorter spans between transducers.
MTG 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 providing payback on your investment.
Physically MTG is a single (2” standard – 4”) S.S. probe instrument that installs from one tank top flange in sections. The standard configuration requires only one Intrinsically Safe electrical connection for power (7 – 14Vdc), signal (MODBUS RTU), and I.S. ground. Physically fewer terminations or potential failure points than tank gauging systems using multiple instruments and multiple tank openings.
The MTG does not require a gauge well but can fit within an 8” or larger gauge well along with enough room for manual hand lines or sampling. This allows the verification of all measured parameters for Volume by Hybrid (Level, Temperature, Density, & Water) or Hydrostatic (Mass, Density, & Water) Method from the same physical location and product media. The ability to verify ATG calibration and to prove accuracy in comparison to the known reference.
MTG is bottom referenced using a magnetic footer and at the top flange it uses an O-ring seal to allow for any tank bottom or roof movement. A TRMI “Tank Reference (bottom and roof) Movement Indicator” physically shows reference point movement (or potential measurement error) from outage measurement. Note: The TRMI can be automated for remote measurement and used within TG SOFT SERVER for a displayed parameter.
All MTG probe sections and sensor housings are precision machined and measured to determine the exact location and downward orientation of each high accuracy absolute pressure transducer and Class A, 100 Ohm Platinum, four wire RTD.
MTG is flexible in design, can be engineered, and manufactured to meet the needs of multiple applications. MTG is installed in tank heights that range from 8’ (2.43m) to 265’ (80.77m) and used within all types of products; clean (gasoline, JP, etc.) to dirty (crude oil, grease, lubricant additives, etc.) products.
MVS 3002 Multi-function Vapor Sensor – Provides a means for Rupture Protection, i.e., tank over pressure and vacuum that is not addressed within API 2350 or IEC 61511 Overfill Protection. MVS 3002 measures Vapor & Ambient pressure, temperature, and calculates density.
The MVS 3002 when in conjunction with the GSI TG Soft Server Historian, can be used to determine the current settings of Pressure Relief Vents (PRV) installed on a tank. The Historian provides data from every scan, allowing you to trend the time a PRV opened, at what pressure, and for how long. The information can be then used to modify settings of your PRV’s (See API 2000). The MVS 3002 can also be used to monitor any gas blanketing on a tank, i.e., making sure the pressure is correct to stop the formulation of vapors.
The MVS 3002 is designed for use on fixed or cone roof storage tanks. A short probe (2’ – 4”) with one sensor in atmosphere and one sensor in vapor space below the roof. Uses one 4” top flange.

The MAP 3004 is a ridged 2” SS probe with one ambient sensor above the roof, one vapor sensor below the roof, and two middle sensors used for continuous measure of liquid within alarm range. It uses one 4” top mounting flange. The 2’ ridged MAP 3004 is hung from the top flange into the tank.
MOP 3006 Multi-function Overfill (and Rupture) Protection – It provides both Overfill Protection (in accordance with API 2350 and IEC 61511) and Rupture Protection (MVS 3002capabilities) from one instrument. When used as the Secondary alarm system, the MOP 3006 will provide continuous monitoring of Level, Temperature, and Pressure measurement over the probe length (Critical High (CH), ASOP or MSOP, High-High (HH), Maximum Working (MW) level, and Minimum Working Level) on fixed or cone roof tanks. The MOP 3006 is a 2” SS probe with one ambient sensor above the roof, one vapor sensor below the roof, and three middle sensors used for continuous measure of liquid within alarm range. It uses a 6” or larger gauge well or 4” or larger top mounting flange. The MOP 3006 is a bottom referenced probe with optional capability for TRMI “Tank Reference Movement Indicator”.
The MOP 3006 can be used as a standalone “secondary alarm” gauge or within the MTG 3018 (MTG 3012 for Inventory & MOP 3006 for secondary alarms) or MHP 3055 (MTP 3050 & MOP 3006) configurations. Both the MTG 3018 and MHP 3055 have two independent transmitter boards and sensor arrays within one 2” probe. The MTG 3018 and MHP 3055 provide a higher level of redundancy. The 2” probe will fit within an 8” or larger gauge well without interfering with manual reference hand lines and sampling.
