In the Calibration, Display, and Interface segment, we provide the essential connectivity layer that links tank-top instrumentation to control room operations. These solutions form the “connective tissue” of a modern fuel storage ecosystem.
Devices such as the L&J MCG 1350 replicate tank gauge readings at ground level.
Tools such as the MCG 2150 enable technicians to:
These solutions are foundational in Terminal Automation, Inventory Reconciliation, and Maintenance & Safety workflows.


A tank sensor is only as useful as the data it provides — and the accuracy of that data.

Most tank-related injuries come from climbing. GLDs keep operators safely on the ground.
Field interfaces digitize readings at the source, eliminating transcription errors and manual “clipboard” mistakes.

Regulatory bodies (API, OIML) require routine, documented calibration.
Even the most advanced tank gauge has limited value if its data stays trapped at the top of the tank. Calibration, Display, and Interface Solutions form the essential link between field hardware and decision-makers.
From integrating vintage float gauges into a digital control room to checking tank levels during a blackout, these products ensure data remains accessible, accurate, and actionable.
Our Ground Level Displays (GLDs) connect directly to tank-top instrumentation to provide:
All at the base of the tank — eliminating routine climbing and minimizing exposure to hazardous vapors.
Most facilities operate equipment from multiple eras and manufacturers. Our Interface Units function as universal translators, converting:
Our Calibration Tools empower technicians to:
All from the ground. This streamlines regulatory requirements for custody transfer and environmental compliance.
Loop-Powered Simplicity
Many GLDs and interfaces are loop-powered, meaning:
Transmitter modules are engineered to bolt onto existing mechanical gauge heads (e.g., Varec 2500 ATGs)—without interrupting tank operations.
A full upgrade can be completed in under an hour.
In an industry dominated by proprietary protocols and closed ecosystems, Cognesense provides true interoperability.
