Rosemount™ Tank Gauging by Direct

One System, Total Tank Visibility

Direct combines automation engineering with Rosemount tank gauging technology to deliver complete measurement systems for liquid storage facilities. From design and commissioning to long-term support, we help operations improve inventory visibility, reduce transfer risk, and maintain tighter control over every tank.

  • High-accuracy FMCW radar level measurement for inventory management and custody transfer
  • Integrated measurement of level, average temperature, free water, and pressure
  • Calculated inventory data including gross volume, net standard volume, density, and mass
  • SIL-certified overfill prevention architectures for higher-consequence storage applications

What Sets Us Apart

Built for Critical Storage Operations

The cards below show how modern tank gauging supports the functions that matter most across the tank farm, including custody transfer, overfill protection, roof tilt monitoring, proof testing, and phased modernization.

Custody Transfer Accuracy You Can Stand Behind

Rosemount™ high-accuracy radar tank gauging supports custody transfer applications with repeatable FMCW level measurement, reducing volume uncertainty and strengthening confidence in transfer calculations, inventory reconciliation, and transaction records.

Overfill Protection Built on Independent Measurement

Rosemount™ overfill prevention solutions support independent protection layers, continuous level surveillance, and stronger alarm integrity, helping facilities reduce exposure to undetected level measurement failures during filling and transfer operations.

Inventory Data That Goes Beyond Level Alone

Integrated tank gauging systems combine level, average temperature, free water, and pressure inputs to calculate gross observed volume, net standard volume, density, and mass for tighter reconciliation, stronger reporting, and better daily inventory control.

Roof Tilt Monitoring for Floating Roof Tanks

Radar-based floating roof monitoring helps operators detect abnormal roof tilt, roof sticking, and buoyancy changes earlier, improving inspection visibility, reducing manual rounds, and supporting safer long-term operation of floating roof tank assets through alarm handling and intervention.

Remote Proof Testing That Reduces Field Exposure

Modern continuous radar solutions support remote, in-situ proof testing from the control room, improving verification efficiency, reducing unnecessary field exposure, and simplifying routine testing for overfill prevention and safety instrumented functions.

Modernization Without Replacing Everything at Once

Gauge emulation allows obsolete Float and Tape Gauges and servo gauges to be replaced tank by tank, preserving much of the installed infrastructure while making phased modernization more practical, less disruptive, and easier to implement across the broader facility.

Open Architecture Built for Future Growth

Rosemount™ Tank Gauging uses tank hubs, system hubs, and flexible host connectivity to consolidate measurement and inventory data, simplify DCS integration, and support phased upgrades without locking operations into proprietary field architecture.

The Direct Difference

The Right System, Not Just the Right Gauge

Tank gauging performance depends on the complete system, not just the instrument on top of the tank. Direct evaluates your application and delivers the right combination of radar measurement, temperature inputs, pressure devices, communications, and inventory software without adding complexity you don’t need.

  • Application-focused design for tank gauging, inventory control, and overfill prevention
  • Integrated solutions using radar, temperature, pressure, communications, and TankMaster™ software
  • Support for fixed roof, floating roof, pressurized, cryogenic, LNG, and NGL storage applications
  • Guidance on phased modernization, proof testing, and long-term measurement reliability

What's in your tanks right now?

If you can’t answer that with confidence, outdated or unreliable gauging may be creating more risk, rework, and uncertainty than you realize.

Phased Modernization

Modernize Tank by Tank, Not All at Once.

Float-and-tape and servo automatic tank gauges can drift, hang up, or fail over time, creating false level readings that increase reconciliation issues, safety exposure, and overfill risk. Gauge emulation supports tank-by-tank modernization while keeping existing systems in place where it makes sense.

Free Engineering Assessment

We review your current gauging system, identify measurement gaps, and show where modernization will deliver the most value.

Start with Your Highest-Risk Tanks

We prioritize the tanks where measurement uncertainty, safety exposure, malfunction risk, or reconciliation errors are creating the biggest impact.

Add Modern Intelligence

We introduce radar, temperature, and hub technology to improve accuracy, simplify proof testing, and give operators better visibility.

Connect to TankMaster™

We unify tank data in one system to streamline reporting, reconciliation, alarming, and day-to-day inventory management across the facility.

What Our Clients Say About Working With Direct

We had an audit coming up and real uncertainty around our overfill prevention documentation. Direct came in, assessed the gaps, and got us where we needed to be without a full system rip-out. They knew exactly what compliance required and built the project around that.

Compliance and Safety Manager

What I appreciated most was that they didn’t try to oversell us. They looked at our tanks, asked the right questions, and told us exactly what we needed and what we didn’t. The system has been running clean since day one and our reconciliation numbers have never been better.

Plant Engineer

We’ve worked with a lot of integrators over the years. Direct is one of the few that actually shows up after the project is done. When we had an issue with our DCS communication six months after commissioning, they were on it the same day. That kind of support is hard to find.
