Remote Calibration

MCG 2150

Wireless setup and service, sealed housing intact.

What It Is & How It Works

A remote calibrator is a handheld, battery-powered device that allows technicians to program, calibrate, and troubleshoot tank gauging instruments without opening explosion-proof enclosures or making physical wiring connections. Using infrared communication through the instrument’s readout window, the calibrator accesses the gauge’s full configuration menus, calibration parameters, and diagnostic data from a safe working distance.

The operator stands within approximately ten feet of the instrument, selects the gauge address, and uses the numeric keypad to navigate setup and calibration functions. The calibrator sends commands and receives responses through the instrument’s infrared pickup, enabling level verification, temperature readout, display format changes, communication settings, and field calibration, all without breaking the explosion-proof seal. This wireless interaction preserves the integrity of the hazardous-area rating throughout the entire service visit.

The MCG 2150 is intrinsically safe (UL Class I Groups C & D; ATEX Zone 0 Ex ia IIC T5) and requires no permanent installation. Compact and portable, it moves from tank to tank during commissioning or routine maintenance with no cables or adapters. A single device services radar gauges, servo gauges, transmitters, and ground level displays across the entire tank farm.

One distinction worth noting: a purpose-built remote calibrator communicates natively with L&J Technologies instruments, providing full access to gauge-specific parameters, diagnostic routines, and calibration procedures that generic communication tools cannot reach.

When to Choose Remote Calibration

Initial Commissioning Programming new radar, servo, and float & tape gauges during installation without opening housings in classified areas.
Routine Calibration & Verification Periodic accuracy checks and adjustments as part of scheduled maintenance programs.
Troubleshooting in Hazardous Areas Diagnosing communication, signal, or configuration issues in Class I Division 1 or ATEX Zone 1 environments without de-energizing or breaking seals.
Multi-Tank Commissioning & Maintenance Large tank farms where reducing setup time per instrument directly lowers commissioning cost and schedule.
Retrofit & Upgrade Projects Reconfiguring existing gauges after firmware updates, transmitter replacements, or measurement system changes.

Why It Excels

Hazardous Environments Requiring Sealed Enclosures

Performs full setup and calibration without opening explosion-proof housings, maintaining hazardous-area certification integrity throughout the process.

Facilities with Many Tanks and Tight Commissioning Schedules

A single portable device services every compatible instrument on the site, eliminating per-tank wiring setups and reducing time at each location.

Sites Requiring Consistent, Repeatable Configuration

Menu-driven prompts guide technicians through standardized calibration sequences, reducing variability across instruments and operators.

Applications Where Tank Climbing Must Be Minimized

When paired with a ground level display, the calibrator enables full gauge service without ascending the tank structure.

What to Consider Alongside Remote Calibration

Consider an alternative when:

You need to configure network parameters, alarm logic, or multi-tank data architecture rather than individual instrument settings. See Field Interface Devices & RTUs.
You need centralized calibration records, audit trails, and compliance reporting beyond what field-level interaction provides. See FuelsManager®.

How Remote Calibration Fits Into a Larger System

Pair with servo gauges, radar gauges, and float & tape transmitters as the field commissioning and maintenance tool that keeps instruments properly configured throughout their service life. See Servo Level Gauges, Radar Level Gauges, and Float & Tape Transmitters.
Pair with ground level displays (MCG 1350M) for a complete ground-level service architecture where the display provides daily operator access and the calibrator handles periodic setup and recalibration. See Ground Level Displays.
