Measured
Flow meter
Counts every pulse at the pump outlet. The liter that left, not an estimate.
Tank telemetry + RFID release
Tank telemetry that sees every liter.
Track level in real time, release fueling by RFID card, and know the instant fuel leaves outside the normal flow — using the sensor already on your tank.
- Live in Brazil and Japan
- Real time over WebSocket
- Offline-resilient
Compatibility
Works with the sensor you already have.
No proprietary hardware locking you in. The DP Core Board reader speaks the industry-standard sensors — and any 4–20 mA probe is on the list.
-
Hydrostatic probe 4–20 mA
The reader's default input: bottom pressure turned into a stable level reading.
-
Radar 4–20 mA
Non-contact measurement for aggressive products or foam.
-
Any 4–20 mA sensor
Ultrasonic, pressure, capacitive — the industry current loop.
-
Standard resistive float
The common tank float on a resistive divider. Guaranteed compatibility.
-
PT100 — product temperature
Immersed probe reading the actual fuel temperature.
-
Tank lid
A contact sensor that flags the moment the tank is opened.
One reader, one level source — picked in software at setup, no board swap. The second input can take the temperature probe.
Precision
Point-by-point calibration for any tank shape.
In a horizontal cylinder, a dished bottom or an odd shape, level does not turn into liters linearly. You measure real liters at several points and TankFlow fits the curve — true accuracy without an expensive sensor.
- 1Strap against the pump: enter the level and the real liters at each point.
- 2The platform builds the level → liters curve and recomputes all history.
- 3The same curve is pushed to the reader: display, cutoffs and limits stay coherent.

Measurement
We measure twice, down independent paths.
The flow meter counts liters at the pump outlet. Telemetry measures the level drop inside the tank. Both numbers sit side by side — and the gap between them is your proof that the measurement is honest.
Cross-check
Level drop
Tank telemetry measures the same fueling from the inside, independently.
Why it matters
- Without a flow meter, volume still comes from the level drop — nothing stops working.
- With one, the report shows measured and estimated side by side, and the gap becomes an accuracy indicator.
- It answers “how do I know this number is true?” without asking for trust.
Security
Fuel went missing? You know right away.
TankFlow detects product coming in and going out from the telemetry itself — with no one keying anything in. A withdrawal outside the normal flow becomes an alert and an audit record.
Unaccounted loss
A level drop with no RFID fueling — possible theft or leak — detected, logged and classified.
Automatic refill
Product coming in is born from the rising level, with volume and invoice reconciliation.
Runout forecast
Days left to the minimum level — refill before you run dry.
Stock reconciliation
Does your fuel add up?
The question nobody can answer without dipping the tank every day. TankFlow answers it on its own, because it already has the three legs of the equation — and whatever is left over is your alert.
- Inflows Refills are born from the rising level, with volume and invoice reconciliation.
- Outflows Fuelings are measured at the pump and tied to card, operator and vehicle.
- Actual The closing level comes from telemetry, not from a manual dip.
opening + inflows + adjustments − outflows = expected variance = actual − expected The traffic light, at industry thresholds
- < 0.5% Within normal
- 0.5 – 1% Worth watching
- > 1% Investigate
Manual adjustment, reason required
A movement outside the automatic flow — an undetected delivery, consumption without a card — is entered as a signed record, with a reason that stays in the report. It is not about zeroing the variance: what remains is still the real alert.

Setup
Live in minutes, not in a construction job.
The reader reuses the existing sensor and starts streaming as soon as it is provisioned. No server, no new network wiring.
- 1
Connect to the tank sensor
Wire the reader to the 4–20 mA probe already in place — hydrostatic, radar or ultrasonic — or to the tank's resistive float.
- 2
Power up and join WiFi
Plug it in and connect. The device opens its own setup portal.
- 3
Provision by QR
Scan the QR in the panel and telemetry starts flowing. Calibration and RFID in the browser.
The platform
Everything the tank needs, in one panel.
Real-time dashboard
Level, liters and temperature live, no page reload.
RFID release
Energizes the pump by card, with time rules and daily limits.
Live wallboards
Build a screen with the tanks you want, in the order you want, and leave it running on the control-room TV.
Public share link
Send the wallboard as a link to people without a login — read-only, those tanks only, revocable at any time.
Automatic detection
Refill and unaccounted loss are born from the telemetry.
Flow metering
Liters are counted at the pump outlet, not estimated. Level becomes the cross-check.
Consumption per vehicle
Plate, odometer and km/L for each vehicle, recomputed at every fueling.
Attendant app
Scan the vehicle QR, type the odometer, link it. No login, nothing to install.
Maintenance history
Tank service records with photos and dates, alongside the asset sheet.
Runout forecast
Refill before you run dry, based on real consumption.
Product temperature
Immersed PT100, with range alerts and future temperature correction.

Offline resilience
Persistent queue and whitelist on the device: network drops, fueling goes on.
Remote management
Calibration, commands and firmware updates from the panel.
Platform security
What protects your data, and your customer’s.
The section above is about protecting the fuel. This one is about protecting the information — the part that shows up in the vendor questionnaire and often decides the contract.
Isolation between accounts
Enforced at the data layer, not by a screen filter: one account cannot reach another’s data, even if the application slips.
Device key stored only as a hash
The plaintext key is shown once, at setup. The platform keeps only the hash — not even support can recover it. Revocable at any time.
The rule does not loosen offline
Who may fuel is evaluated by the same logic online and offline. Losing the network never becomes extra permission.
Public links scoped and revocable
Wallboards and the attendant app open without a login, but each link only covers what was written into it. The platform keeps just the hash, and revoking takes effect immediately.
Secrets encrypted at rest
Your devices’ network passwords are stored encrypted (AES-256-GCM). Operator PINs and user passwords, hashed only.
Role-based access, plus client portal
Operator, manager and administrator see different surfaces. The tank owner, when granted access, sees only their own data.
Corporate login for authentication and encrypted traffic end to end, including between the readers and the cloud.

FAQ
Common questions about TankFlow.
Does TankFlow work with the sensor already on my tank?
Yes. The reader speaks any 4–20 mA probe — hydrostatic, radar, ultrasonic or capacitive — and the standard resistive float too. You do not replace the tank hardware.
How do you measure liters accurately in an odd-shaped tank?
With point-by-point calibration: you strap the real liters at several levels and the platform fits the level → liters curve. It works on horizontal cylinders, dished bottoms or any shape.
Does the system detect fuel theft or leaks?
Yes. A level drop with no RFID fueling is automatically detected as an unaccounted loss, raises an instant alert (email, WhatsApp and push) and is logged for audit.
Do I need a server or construction work to install it?
No. You wire the reader to the sensor, power it, point your phone at the QR and provision. Telemetry starts in minutes and the reader keeps working even offline.
How does RFID fueling release work?
The operator taps the card and the pump is energized, with time rules and daily limits per operator and per tank. Volume is measured by the flow meter at the pump outlet; without that sensor, it is estimated from the tank level drop.
Which fuels and reports are supported?
Diesel, gasoline, ethanol and AdBlue/Arla32, among others. Reports include stock reconciliation, consumption, runout forecast, fueling and movements, exportable to CSV and PDF.
Can I manage several tanks and clients in one account?
Yes. TankFlow is multi-tenant: you manage many clients and tanks in one account, with isolated data, in Portuguese, English and Japanese.
How does TankFlow measure the liters of each fueling?
With a flow meter at the pump outlet, liters are counted pulse by pulse — measured, not estimated. Telemetry measures the same fueling from the tank level drop, independently, and both numbers sit side by side as a cross-check. Without the flow meter, volume still comes from the level drop.
Can I track average consumption (km/L) per vehicle?
Yes. You register the vehicle by plate and enter the odometer at each fueling; TankFlow computes km/L using the full-tank method and tracks the average per vehicle over time. An odometer lower than the previous one is flagged as suspect instead of producing negative consumption.
Does the pump attendant need a login to record a fueling?
No. The Live Fueling app opens from a link — no login, nothing to install from an app store: the attendant scans the QR on the vehicle, checks the plate and types the odometer. The link is scoped to one client and the chosen tanks, only allows linking vehicle and odometer, and can be revoked at any time.
Can I put the tanks on a TV or send them to someone without a login?
Yes. You build a wallboard with the tanks you want, in the order you want, and leave it live on the control-room screen. To show it to someone outside the account — the tank owner, the fuel supplier — generate a public link: whoever opens it sees only that wallboard, read-only, with no access to the rest of the account. The link can be revoked at any time.
