How We Monitor Tank Inventory by Weight: A Recent Installation in Fort Wayne

Earlier this year, our team got a call from a manufacturer in Fort Wayne that was expanding their storage area. As part of the build-out, they needed a better way to monitor inventory in three new 12,000-gallon vertical double-wall tanks.

Their team had already run into the usual challenges. Manual dips meant climbing ladders and hoping measurements were accurate. Traditional level sensors weren’t ideal either—temperature swings, foam, and varying material densities can all affect readings. They wanted something more dependable.

The solution we recommended was weight-based monitoring.

Why Weight Works Better for Tank Inventory

When you measure by weight instead of volume, you eliminate many of the variables that cause inaccurate readings. Density changes, foam buildup, and temperature fluctuations don’t affect the measurement the same way they can with level sensors.

But getting accurate weight readings from tanks requires the right setup from the start.

One of the first decisions we made with the customer’s engineering team and tank fabricator was switching from flat-bottom tanks to legged tanks. That change makes a significant difference when load cells are involved.

Flat-bottom tanks distribute weight across a large surface area, which can introduce flex and inconsistent readings over time. Legged tanks, on the other hand, allow the entire load to transfer directly through the support points.

You can think of it like placing a scale under the legs of a sturdy workbench instead of trying to weigh something sitting on a flexible surface. The measurement is simply cleaner and more reliable.

The Equipment Behind the System

For this installation, we used the B-TEK EZTM tank-mount load cell system under each tank. These load cells are designed specifically for vessel weighing applications and perform well in indoor industrial environments. They’re corrosion-resistant, durable, and relatively simple to maintain over the long term.

Once the tanks were installed on their supports, integrating the load cells underneath was straightforward. Proper installation ensures the weight from each tank transfers evenly through the load cells, which is critical for maintaining accuracy over time.

The system will be powered by B-TEK T405S programmable weight indicators, which we’ll finish installing and commissioning soon.

These indicators do much more than display a number on a screen. They allow us to program high and low thresholds, connect relays, and integrate alerts directly into the facility’s operations.

In this case, the indicators will control several safety and monitoring features, including:

• Stack lights that warn operators when levels approach limits
• Audible alarms if tank levels move outside normal ranges
• Automatic shut-off valves on fill lines to prevent overfilling

In practical terms, the system monitors tank weight continuously and reacts before problems occur. Operators don’t have to guess about levels, and the risk of spills or unexpected shortages drops dramatically.

Preventing Problems Before They Happen

We’ve seen similar systems make a big difference at other facilities. At one site last year, a relay shut off a filling operation during a night shift just moments before an overfill occurred. Without that automated control, the result would have been a messy and potentially costly environmental issue.

For the Fort Wayne manufacturer, this installation represents the first phase of a larger expansion project. One of the advantages of a weight-based system like this is that it scales easily. Additional tanks can be added later, and the indicators can integrate with broader plant controls if needed.

Why Accuracy Matters in Bulk Storage

Tank monitoring isn’t the most visible part of an operation, but it plays a critical role. Even small measurement errors can compound quickly when large volumes of material are involved. A few percentage points of inaccuracy can mean lost product, unexpected downtime, or compliance issues.

By measuring weight directly, facilities gain a much clearer picture of what’s actually in their tanks at any moment.

If your operation is running into similar challenges with bulk storage monitoring, weight-based systems are worth considering. Our team has installed and supported these systems across a range of industrial environments, and we’re always happy to talk through what might work best for a specific setup.
