Fuel Monitoring System in Umaria: Diesel Level on Your Phone

Start with a tipper working the mine belt. Its day is a chain of loading waits, short hauls to a siding and returns to the pit, and diesel keeps burning even while the truck sits in a queue with the engine running. With a fuel record the owner can open one trip, see the level fall from loading point to siding, and compare it with the same run last week. A tipper that burns clearly more on an identical run is a question worth putting to the driver.

A cab that serves Bandhavgarh visitors lives to a different rhythm. It leaves for the Tala, Magdhi or Khitauli side with guests, waits near the park, and comes back after hours the owner never sees. If the cab runs on diesel, the tank record shows what the day consumed beside the route history. When a driver claims extra distance for a guest, the level and the route can be read together, so the owner settles the matter with figures instead of tempers.

School and staff buses around Umaria, Pali and Chandia run the same loop every term day, which makes them the easiest vehicles to judge by fuel. A bus on a fixed route should burn a steady amount each week, so a week that suddenly differs stands out in the report. The transport in-charge need not investigate daily. One look at weekly consumption, set against distance covered, shows whether the bus behaves as usual or deserves a closer look.

Diesel pickups that carry goods or run collections for traders in Umaria make the fourth group. They stop often, carry mixed loads and are driven by whoever is free, so mileage swings from week to week. A level sensor makes every refill visible and every day's use measurable. Owners of petrol cars and bikes should note that the package depends on a diesel tank probe, so for those vehicles please message first and BearTech will say what fits.

The package is ₹19,999 per vehicle. That single figure covers the Teltonika FMB920 tracker, one fuel level sensor, the fitting, Trakzee Premium software, an Airtel SIM and a one-year warranty with AMC. Whichever brand you take, the figure does not move, so you can pick the sensor that suits the tank without worrying about the price difference. From the second year, the software and SIM service renews at ₹3,000 per year. This is the number to remember when you compare quotes.

For one vehicle the arithmetic is short. Year 1 is ₹19,999. Year 2 adds a ₹3,000 renewal and the running total becomes ₹22,999. Year 3 adds another ₹3,000 and the total reaches ₹25,999. Over three years that works out to about ₹8,700 a year for each vehicle, with the sensor, tracker and fitting all inside the package. Outstation fitting adds only the executive's travel and stay.

Now take a small Umaria fleet of three: two coal tippers and one school bus. Year 1 is 3 × ₹19,999, which is ₹59,997. Each of years 2 and 3 adds 3 × ₹3,000, or ₹9,000. The running totals are ₹59,997, then ₹68,997, then ₹77,997 at the end of year 3. The numbers are plain multiplication and assume the same package on every vehicle. Add or remove vehicles from the example and the same multiplication still holds.

Two items sit outside that example. Travel and stay for the executive's visit to Umaria are paid by the client and are quoted before you order. If a vehicle carries two tanks, the extra sensor is priced separately on request, because the package covers one sensor. Since price may vary with requirements, a fleet owner should ring or message 97526 44035 to get the current rate before planning a budget. Nothing else is hidden in the package figure.

Omnicomm LLS-AF 4 is the wired choice. Its cable runs into the tracker's analog input and it draws current from the vehicle, so there is no sensor cell to replace or forget about. The body is sealed to IP69K, works from −40 to +80 °C and suits 12 volt and 24 volt electrical systems. For coal trucks and tippers that live in dust, mud and vibration, that cable-and-sealed-body design is a natural fit.

Mercetech is the Bluetooth option. The sensor talks to the tracker over Bluetooth, so no signal cable has to cross the vehicle, and the probe is fitted from the upper side of the tank by BearTech. It suits vehicles where routing a cable would be awkward, such as a van with a tank far from the tracker. Its battery wears with use and is excluded from the warranty. For other tanks, BearTech will say frankly which one it prefers and why.

Mielta Fantom also talks Bluetooth, version 5.0, and carries a long-lasting battery of its own. It is sealed to IP67, senses temperature and tilt, and bolts on through a steel flange with four bolts, which works with metal or plastic tanks. Its set-up and calibration go through Mielta's own phone app. A school bus on a fixed route, with a tank that stays in one position, suits it well.

Choosing comes down to three questions. Do you want a cable to the sensor? How rough is the vehicle's daily life? Is the tank metal or plastic? Because the price does not change, pick for the tank, not the budget. Final model and probe length are fixed by BearTech once the vehicle has been inspected, and a comparable model may be supplied if the named one is out of stock. Tell us the tank material when you write, as it often decides the choice.

From end to end the district is about 150 km long and only about 60 km wide, so vehicles tend to follow a few corridors. Umaria is tied by road to Shahdol, Rewa and Katni, and a diesel vehicle on those routes burns fuel in long steady runs. A level sensor lets you judge each corridor by what it actually consumes, instead of by the driver's account of the trip. Little in this picture is guesswork once the readings are in front of you.

Coal work adds idling. Trucks queue near mines and sidings, engines running, and a tipper can burn a surprising amount while waiting its turn. Idling is nobody's idea of a trip, yet it appears in the tank. Reading the stoppage report together with the fuel level shows how much diesel went into waiting, which helps an operator decide whether better scheduling would matter more than any other change. Few rural carriers can answer that without a dated record to read.

Tourist cabs and school buses add the other side of the district's pattern. Cabs run to Bandhavgarh in bursts when visitors arrive, so their diesel use rises and falls with the season. Buses burn evenly and predictably. Having a fuel record for both makes each vehicle comparable with its own history, which is the fairest test of whether something has changed. That kind of comparison is far fairer than comparing vehicles against each other.

Because the district's roads are few, a vehicle that goes elsewhere stands out. A truck whose tank level falls on a road that is not on its normal route is easy to spot when location and fuel are shown together. That does not mean wrongdoing every time. It means the owner has the facts at hand and can ask a better question than 'where was the truck yesterday?' Good questions start from facts, and the dashboard supplies them.

Inside the tank sits a capacitive probe. When diesel climbs the probe, the electrical reading shifts, and the sensor turns that change into a number. The probe is shortened to the depth of the tank during fitting, so a deep tipper tank and a shallow van tank each get a probe of the right length, up to about 3 m. Calibration then links readings to actual litres.

The Teltonika FMB920 tracker collects that fuel number together with the vehicle's location, ignition and movement. With an Omnicomm sensor the number reaches the tracker through a cable into the analog input. With Mercetech or Mielta Fantom it reaches the tracker over Bluetooth. Either way, the tracker has both the position and the level, so every fuel reading carries a place and a time. Keep the slip's date and the vehicle number together so matching takes seconds.

The tracker sends the data through the Airtel SIM to Trakzee Premium, which draws the level graph, records refills and warns you if the level drops sharply. You see this on the mobile app for Android and iOS, or on the web. For a school bus, the picture may be a flat line with a refill each week. For a coal tipper, it may be a sawtooth of daily burn and refill.

All of this depends on a fitted, calibrated sensor and on Airtel coverage in the area where the vehicle runs. If the vehicle drives through a patch with weak signal, the live view can lag until the connection returns. The fuel reading itself comes from the probe in the tank, which does not care about signal, but your phone only learns it once the tracker can report. Planning gets easier once the pattern is written in the tank record.

Accuracy first. BearTech's figure is about 95% under normal conditions, after proper installation and calibration. It is not a laboratory reading. The result depends on the tank's shape and state, the quality of the fuel, the slope the vehicle stands on, and how much the vehicle is moving. A tank with odd internal baffles or a tilted standing spot will read less cleanly than a regular tank on level ground.

The system informs and warns, nothing more. It cannot keep a determined person away from the tank, and it does not lock anything. If you want a physical barrier against siphoning, that needs a different product. What you get here is a record that shows when the level fell and where the vehicle was, so you can act sooner and with evidence in hand. A clear photo of the tank opening saves a long chain of messages.

Live data depends on Airtel coverage where the vehicle runs. In a weak-signal stretch the dashboard may show older data until the tracker reconnects. The wireless sensors, Mercetech and Mielta Fantom, use an internal battery, and that battery is a wear item that the warranty excludes. The Omnicomm wired sensor draws power from the vehicle and has no such battery. The more you tell us at this stage, the fewer surprises on the day.

Finally, the commercial limits. Once an order is placed it cannot be returned, refunded or exchanged, so choosing the right sensor before ordering matters. The one-year warranty and AMC cover the tracker and the sensor under their terms. Because of these limits, BearTech prefers a short call before the order, so that every vehicle on your list is a good fit before money changes hands. Please save these numbers on every driver's phone as well.
