Introduction

Calibration, Display & Interface Solutions

What Kind of Fuel Storage Solutions Do We Offer?

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.

Field Interfaces & Transmitters

Examples Include:
  • Varec 2920 FTT
  • L&J MCG 2000 Series

These devices:
  • Convert mechanical movement into digital data.
  • Translate proprietary protocols into open standards (Modbus, Profibus, Ethernet).
  • Deliver tank data directly to SCADA or terminal automation systems.

Calibration Tools & Handhelds

Tools such as the MCG 2150 enable technicians to:

  • Configure Gauges
  • Set Alarms
  • Validate Accuracy
  • Perform calibration without opening the tank, eliminating exposure to vapors
MCG 1350M

Ground Level Displays (GLDs)

Devices such as the L&J MCG 1350 replicate tank gauge readings at ground level.

Key Benefit

  • Operators read levels, alarms, and temperatures without climbing the tank.

In What Applications, Products, or Services Are They Used?

These solutions are foundational in Terminal Automation, Inventory Reconciliation, and Maintenance & Safety workflows.

01

Applications Include

  • Bridging legacy mechanical tanks with modern digital systems.
  • Bringing 40–50 year old float gauges online.
  • Local viewing during power outages or control system failures.
02

Products & Services Support

  • System Commissioning
  • Annual Verification, Calibration & Audit Support
  • Ensures the control room reading precisely matches the liquid level in the tank.

Why Add Calibration & Interface Tools to Fuel Storage Applications?

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

Safety (Reducing Tank Climbing)

Most tank-related injuries come from climbing. GLDs keep operators safely on the ground.

Data Integrity

Field interfaces digitize readings at the source, eliminating transcription errors and manual “clipboard” mistakes.

Compliance & Custody Transfer

Regulatory bodies (API, OIML) require routine, documented calibration.

Introduction to Calibration & Interface Technology

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.

These Solutions:
  • Replicate tank data at eye level
  • Convert legacy or proprietary signals into modern protocols
  • Provide the access points required to verify and calibrate instruments

From integrating vintage float gauges into a digital control room to checking tank levels during a blackout, these products ensure data remainsaccessible, accurate, and actionable.

How It Works & Key Advantages

01

Keep “Boots on the Ground”

Our Ground Level Displays (GLDs) connect directly to tank-top instrumentation to provide:

  • Level
  • Temperature
  • Alarm Indicators

All at the base of the tank — eliminating routine climbing and minimizing exposure to hazardous vapors.

02

Universal Signal Translation

Most facilities operate equipment from multiple eras and manufacturers. Our Interface Units function as universal translators, converting:

  • Varec Mark/Space
  • Enraf
  • L&J Proprietary Signals into standard formats like Modbus, Ethernet, or Profibus. This enables modernization without expensive full-system replacement.
03

Simplified Calibration & Compliance

Our Calibration Tools empower technicians to:

  • Trigger Float Lifts
  • Check Reference Points
  • Verify Gauge Hysteresis
  • Document Calibration

All from the ground. This streamlines regulatory requirements for custody transfer and environmental compliance.

Installation & Retrofit Considerations

Loop-Powered Simplicity

Many GLDs and interfaces are loop-powered, meaning:

  • No Added Conduit
  • No Additional Power Supplies
  • Lower Installation Cost
  • Faster Deployment

Non-Intrusive Upgrades

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.

Why Cognesense?
