What Gauging Systems does
Gauging Systems Inc. (GSI) is a privately held, Texas-incorporated manufacturer of tank gauging and loss control instrumentation for bulk liquid storage tanks, founded in 1983 in Sugar Land, Texas. The company designs and produces a portfolio of proprietary hardware instruments — most notably the MTG Multi-function Tank Gauge (which the company states provides over 135 data registers per poll versus an industry standard of 5) and the 3100 MMP Multi-Media Probe for custody-transfer-grade level, temperature, and water/interface measurement — alongside mechanical float-and-tape gauges (2570), magnetic level gauges (2550), capacitance encoders (2110), digital transmitters (2000), high-level alarm switches (4100 HLAS), annunciator panels (4130), communications interface modules (1570 CIM), and transmitter boards (APTB 3.6). All instruments support industrial protocols including MODBUS RTU/TCP, MQTT, Mark-Space, and Tankway, with NEMA 7 explosion-proof enclosures and SIL2 ratings.
The company's software platform, TG Soft Server, is a Linux-based tank monitoring application that aggregates data from GSI and third-party gauges, providing inventory tracking, overfill/rupture protection, leak detection, vapor monitoring, and alarm processing via a browser-based interface with integrations to SAP, SQL, OPC, and MQTT. Revenue is generated through four streams: (1) hardware sales of the gauging instrument portfolio, (2) software subscriptions for TG Soft Server, (3) engineering and field services including installation supervision, FAT/SAT, training, and bench/field repair for both GSI and legacy third-party systems (Varec, L&J, Whessoe, Motherwell, Protectoseal, GPE), and (4) recurring preventative maintenance contracts. GSI sells exclusively through a direct sales-led model with no channel partners, targeting petroleum and petrochemical operators as the primary vertical, with secondary exposure to power, marine, food & beverage, pharmaceutical, pulp & paper, and water/wastewater end markets.

The offering also includes engineering services, installation supervision, Factory/Site Acceptance Testing, training, warranty/field/bench repair, and preventative maintenance contracts.
Product overview
Gauging Systems offers a comprehensive tank gauging and loss control ecosystem combining hardware instruments with software platforms. The core hardware portfolio centers on the MTG Multi-function Tank Gauge Family and 3100 MMP Multi-Media Probe for custody transfer-level measurements, complemented by mechanical float-and-tape gauges (2570), magnetic level gauges (2550), capacitance encoders (2110), digital transmitters (2000), alarm switches (4100 HLAS), annunciator panels (4130), and communication interface modules (1570 CIM). The TG Soft Server software platform serves as the central command hub, integrating with all gauges for real-time monitoring, alarm processing, and enterprise data exchange. Transmitter boards (APTB 3.6) provide the critical interface between gauges and host systems. This integrated approach enables inventory control, overfill prevention, leak detection, and vapor monitoring across petroleum, petrochemical, and industrial applications.
