Fuel Monitoring System in Raigarh: Diesel Records for Coal Tippers and Plant Trucks

A fuel monitoring system in Raigarh must make sense of a district built on heavy haulage. Raigarh town sits on the Kelo river and on the Mumbai to Howrah railway, with Odisha just to the east and Jashpur, Korba, Sakti and Sarangarh-Bilaigarh around it within Chhattisgarh. Roads lead out towards Bilaspur, Korba, Jashpur and Odisha, and trucks use all of them.

Coal sets the strongest pattern. In the north and north-west, around Dharamjaigarh, Gharghoda, Tamnar and the Mand-Raigarh belt, tippers and trucks shuttle between pits, sidings and plants. A single cycle has a short drive, a wait to load, another drive, a queue at the weighbridge, unloading and the empty run back. Much of the diesel goes into those waits, with engines idling, and none of it shows on a distance report.

Industry adds more loops. Steel, sponge-iron and power units send their products and by-products, fly ash among them, out on trucks and tippers. Plant contractors run staff buses and vans between Raigarh, Kharsia, Punjipathra and the plant gates at every shift change. Taxis head for Bilaspur and towards Jharsuguda, and construction sites keep tippers and site vehicles busy, especially in the dry months.

The calendar shifts the load. The monsoon usually slows haul roads and loading in open-cast areas, so queues grow and cycle times stretch. Paddy is cut from about October, adding tractors and farm pickups around Pusaur and Kharsia. And the Chakradhar Samaroh, held around the Ganesh festival, brings visitors and hired vehicles into town. Through every season the diesel bill is large, and it is spread across hundreds of short, repeated movements. Each of these vehicles spends its diesel in a different rhythm.

Start where the owner starts: the phone. Open Trakzee Premium and each tipper is a marker on the map with a fuel line beside it. The line runs high after a fill, drifts down through the day's cycles, jumps up at the next fill and drops in a step if diesel leaves the tank while the vehicle stands. Each point carries a time and a location, and reports turn the same points into mileage and consumption by day or trip.

Those points come from the Teltonika FMB920 tracker in the cabin. It knows the tipper's position by satellite, its speed and whether the ignition is on, and it receives a fuel level from the sensor: by cable from Omnicomm, or over Bluetooth from Mercetech or Mielta Fantom. It bundles them together and sends them through an Airtel data SIM to Trakzee Premium.

The fuel level itself starts with a probe that stands upright inside the tank. During fitting an opening is made in the upper face of the tank, and the probe is lowered in and cut to the tank's depth. It works on capacitance: as more of its length is covered by diesel, its electrical value changes, and the sensor head converts that into a level. There is no float to stick and nothing that moves.

Calibration joins the two ends. On fitting day, the executive matches the probe's raw values with known quantities of diesel in that tank, so the phone shows litres rather than electrical units. If the tank is replaced, welded or the probe removed for any reason, calibration has to be done again, so inform BearTech before the workshop starts.

Every sensor in the package costs ₹19,999, so think about the vehicle. For Raigarh haulage, three points usually decide: whether a cable from tank to cabin is easy to lay on that chassis, whether the tank is steel or plastic, and whether a battery inside the sensor is acceptable. Dust and vibration on haul roads are the same for all three, so the tank layout matters more. A coal tipper, a shift bus and a tractor rarely give the same answers.

Omnicomm LLS-AF 4 is the wired one. It runs on vehicle power and sends its signal through a cable to the tracker, so it has no battery. On a tipper working the Tamnar or Gharghoda pits for years under one owner, that is attractive: nothing inside the sensor wears out, and the cable is laid along the frame once and left alone.

Mercetech and Mielta Fantom are wireless and use Bluetooth, so no signal cable runs between them and the tracker. Mercetech is handy on a long staff bus where the tank sits far back. Mielta Fantom has Bluetooth 5.0, its own battery, tilt sensing and a steel flange that fits steel or plastic tanks; set-up is through Mielta's mobile app. For contractor pickups and tractors around Pusaur and Lailunga with mixed tank materials, that flange is a real help.

Two notes apply across the board. The batteries in the wireless sensors are consumables outside the warranty. And each probe enters through the top of the tank and is cut to its depth, so BearTech confirms the model and probe length after seeing the tank or a clear photo. If a listed model is out of stock, a comparable model may be supplied.

Per vehicle, the Complete Package costs ₹19,999 plus GST for the first year: FMB920 tracker, one fuel level sensor of your choice, fitting, Trakzee Premium login, Airtel SIM and a year's warranty with AMC. Each year after that, renewal is ₹3,000 per vehicle. BearTech's plan prices, ₹22,999 for two years and ₹25,999 for three, line up with those running totals.

Take a sample fleet, only to show the arithmetic: five coal tippers, two fly-ash trucks and one staff bus, eight vehicles. First year: 8 × ₹19,999 = ₹1,59,992. Each further year: 8 × ₹3,000 = ₹24,000. Two-year total: ₹1,59,992 + ₹24,000 = ₹1,83,992. Three-year total: ₹1,83,992 + ₹24,000 = ₹2,07,992, equal to 8 × ₹25,999. Spread across eight vehicles and thirty-six months, the figure is easier to set beside a monthly fuel bill.

On top comes the executive's travel and stay from Bhopal, paid by you and quoted before the order; with eight vehicles fitted in one visit, that is still a single journey. Fitting tippers in rotation means the pits never stop for the visit. The package covers one sensor per vehicle, so if a tipper has a second tank, raise it while asking for the quote.

What eight sensors are worth to you cannot be worked out in advance. It depends on what the records show: diesel per cycle that is steady across tippers, or one tipper that drinks noticeably more; fills that match slips, or slips that do not. Either outcome is information. Set the three-year total beside a month of your fleet's diesel bills, think about which outcome you expect, and decide. For a quote, call 97526 44035. Give the records at least one monsoon and one dry season before judging.

Here is how one alert might unfold. At 11 at night, the owner's phone shows a sharp fall on a fly-ash truck parked near a siding. The first thing he does is look, not call: the map shows the truck parked, the ignition off, and the location a sloping patch at the edge of the yard. That alone might explain part of the change, because a tilted tank reads differently.

Next morning, before anything else, he compares the level once the truck has been moved to flat ground. Most of the fall has returned, so tilt explains most of it. A smaller step remains. He rings the driver and asks, without accusation, what happened that evening. The driver says a mechanic drained some diesel to clear a blocked filter, and the workshop slip confirms it. The owner adds a line to the register and moves on.

Not every alert ends so neatly, and that is where the habit matters. If no reason fits, save a screenshot with the level before and after, the location, the time and the ignition record, and compare it with the pump slips and the diesel issue register. Look at the place and hour together: a busy siding by day and a lonely road at night call for different questions.

Write each outcome down with date, vehicle, driver and conclusion. After a month you will see whether falls are scattered or keep returning to one vehicle or one stopping place. And keep the system's limits clear with drivers: it records levels and raises alerts, but it cannot lock a tank or physically stop anyone drawing diesel. Caps, locks and yard rules are still your job.
