Technical specifications

An off-road diesel (GNR) tank is hard to keep an eye on: the mechanical gauge ends up sticking, and the dipstick check always happens too late — often the day before a job. This sensor measures the distance between itself and the surface of the fuel by ultrasound, without any contact with the liquid, and sends the level straight to your smartphone or computer.

How it works

The unit is placed above the surface to be measured, at 28 cm to 7.5 m. It sends an ultrasonic pulse and works out the level to within ± 1 cm (plus 0.3 % of the distance). The readings then travel over the multi-network GSM network, thanks to the pre-installed SIM card: no gateway, no antenna, no pairing. You take it out of the box, switch it on, it transmits. The reporting interval can be set to suit your needs, and the same principle works on a silo.

Two engineering precautions: the beam is conical (2 × 20°), so on a very narrow tank it can catch the wall; and the sensor must be protected from condensation and direct splashes, which skew the reading.

No subscription, in practice

The displayed price covers the hardware, the SIM and remote data access. No monthly debit afterwards. The built-in battery keeps it running on its own for a long time; the day it or the SIM plan runs out, you renew them as a one-off — a maintenance expense, not a rent.

Frequently asked questions

Do I need to drill the tank or touch the fuel?

No. The sensor measures by ultrasound, without contact with the liquid. You place the unit above the surface, switch it on, and it transmits. The placement of the unit stays flexible.

Does it work on every tank?

It measures flat surfaces, at a distance of 28 cm to 7.5 m. Two limits to be aware of: detection is conical (2 × 20°), so a tank that is too narrow can return the wall instead of the liquid; and condensation or direct splashes skew the reading — the sensor must be protected from them.

How am I warned when the level is low?

You set your threshold on the platform. When it is crossed, the sensor calls you (up to 10 numbers), or sends an SMS or an email. You can also check the level remotely at any time.

Is there a subscription?

No. The SIM card is included and the sensor runs on its own battery. When the SIM or the battery reaches the end of the road, you top up one and replace the other — a one-off expense, not a monthly rent.
