ST100 Fuel Stations

Fuel management that fits your operation.

The ST100 keeps each fueling simple and accountable.

Manage from your phone or browser

Choose the workflow that makes sense for your crew.

The ST100 is not one rigid process. Choose what needs to be identified at the tank and keep fueling as simple as possible.

  • People and equipment

    Use individual PINs when you want a clear record for both the person fueling and the machine receiving fuel.

  • RFID-based access

    Use optional tags for people or machines to speed up the process and reduce manual entry at the station.

  • Equipment-focused records

    Focus the record on the machine when tracking gallons by unit matters most.

Set the rules from the office.

Decide who can fuel, from which pumps, and what the station asks for. Changes are sent to the station automatically.

  • Give each person their own PIN, and turn it off when they leave
  • Limit a person to certain fuel types or pumps
  • Limit a machine to the right fuel type
  • Ask for a unit number, a meter reading, or neither

Operating schedule

Lock the pumps after hours.

Set the hours each pump is open, day by day. Outside those hours the pump will not start for anyone, so no one fuels when no one is supposed to be around.

  • Hours by day of the week

    Give weekdays and weekends different hours, or open more than once in a day. Each pump can have its own unique schedule or share a schedule.

  • A full lockout

    Outside open hours, no PIN or tag will start a pump. A fueling already underway finishes normally.

  • Enforced at the station

    The station keeps the schedule and its own clock, so the lockout holds when the internet is down. The display shows when the pump opens next.

Easy to connect

Connectivity that works with your yard.

Use the internet you already have when it can reach the station. Add cellular when you need a connection anywhere.

  • Ethernet

    Connect directly to the network you already have in your yard, with no separate connection to pay for.

  • Wi-Fi

    Use the Wi-Fi you already have at the pump and avoid another monthly connection.

  • Cellular when you need it

    Add the optional cellular modem when nothing else reaches the station, and connect the station wherever it is located. Ideal for mobile tanks.

  • Bluetooth setup

    Set up the station from your phone over Bluetooth, right at the station. No laptop or call to support needed.

Works through outages.

Fuel tanks are often a long way from the router. The station keeps the information it needs to authorize and record fuelings when the connection is down, then uploads everything when it comes back.

Stay informed while fueling happens.

  • Fueling started

    Get notified when a pump starts and finishes.

  • People you follow

    Follow a person's fuelings. Supervisors can follow their whole department.

  • Tank running low

    Get the low-fuel alert for the pumps you care about.

Reports

Fuel records that are ready to share.

Pull fuel use by equipment, person, or pump for any date range, then export it to CSV or PDF.

  • See gallons, meter readings, and time for every fueling
  • Filter by date, equipment, equipment type, person, or pump
  • Customize columns shown and order
  • Hand a clean CSV or PDF to your accountant
An approved fueling report of 191 rows: unit number, machine, person, station and pump, gallons, odometer or hours, the difference since the last fueling, and miles per gallon or gallons per hour, with CSV and PDF buttons.

Claiming fuel tax credits or refunds? Your reports give you dated gallons by machine to support the claim.

Maintenance

Fuel records that work with maintenance.

Every fueling can move a machine's service schedule forward, even when nobody reads the meter.

  • Equipment records

    Keep key details, manuals, insurance, and service history with each machine.

  • Maintenance tasks

    Give the crew clear assignments and keep photos, notes, and updates together.

  • Estimated meters

    Turn fuel use into estimated hours or miles, so service schedules keep moving.

Frequently asked questions

Questions about the ST100?

Does the fuel station still work if the internet goes down?

Yes. The station keeps its own list of people, pumps, and permissions, so it can authorize and record fuelings with no connection. Fuelings upload automatically when the connection returns.

How many pumps does one fuel station control?

One ST100 controls up to three pumps on one station. This is ideal for a site having Gasoline, Clear Diesel, and Dyed Diesel.

Does it know how much fuel is in the tank?

The app keeps a running balance by subtracting every gallon dispensed and adding the deliveries you record. It is calculated, not measured by a level sensor, and the built-in dipstick calculator helps you spot-check inventory levels.

Can it stop someone putting diesel in a gas engine?

Yes. Each pump and each machine has a fuel type. If they do not match, the pump will not run.
