Fuel Monitoring System in Sukma: Diesel Records on the Jagdalpur to Konta Road

Sukma lies in southern Chhattisgarh, in the Bastar region, with Dantewada, Bijapur and Bastar as neighbours and the Telangana and Odisha borders beyond its southern and eastern edges. Forest covers much of the land, the hills are low, and around Konta the Sabari river valley opens into flatter paddy fields. Sukma town is the headquarters, and Konta, Dornapal and Chhindgarh are the other names every transporter knows.

Most traffic funnels onto one road. The highway from Jagdalpur runs to Sukma town, then on through Dornapal to Konta near the state line. Side roads branch off to Chhindgarh, other block centres and villages; many are narrow, some unpaved, and a few close in the rains. Rail service in the district is limited, so goods, hostel travel and staff movements depend on road vehicles, and long stretches separate one mechanic from the next.

Construction keeps the heavier vehicles busy. Road and building contractors run tippers and trucks carrying murram, sand, cement and steel between depots and work sites, mostly through the cooler months from about October to March. Their day is a string of shuttles and waits, and diesel goes into loaded climbs and idling at sites as much as into kilometres.

Lighter vehicles follow the rhythm of village life. Pickups and Boleros carry rice, millets, tamarind and vegetables to the weekly haats and return with provisions. In spring and early summer, small trucks move tendu leaf bundles and mahua sacks from villages to collection points. Hostel and school buses carry students at the start and end of terms, shared jeeps link the blocks, and the Bastar Dussehra season brings extra travel towards Jagdalpur.

Take a pickup that goes to the weekly haat. Its diesel tank, steel or plastic, hangs beneath the body. During fitting, the executive opens a small hole in the top of the tank, lowers in a probe cut to the tank's depth and seals it. The probe stays in the fuel permanently. When the tank is full, most of its length is wet; after a long haat-day round, much less of it is.

The probe measures that wet length electrically and converts it into a level. It sends the level to the Teltonika FMB920 tracker in the cabin, over a cable if it is Omnicomm, or over Bluetooth if it is Mercetech or Mielta Fantom. The tracker adds the pickup's position, speed and whether the engine is on, then sends the package of data over the Airtel data SIM to Trakzee Premium.

On the owner's phone, the pickup's diesel shows as litres and as a line on a graph. During the run to the haat the line slopes down; a refill at a pump in Sukma town shows as a sharp rise, with the place and time beside it; a fast fall while the pickup stands parked shows as a drop and sends an alert. If the vehicle passes through a stretch without signal, the live view pauses until it reconnects.

Calibration gives the numbers their meaning. On fitting day, the executive matches the probe's signal to known quantities in that specific tank, so the screen speaks in litres. If the tank is ever replaced or welded, or the probe removed for repair, calibration must be repeated. Let BearTech know before such work, so the record stays trustworthy for the owner.

Inside the ₹19,999 package, Omnicomm LLS-AF 4, Mercetech and Mielta Fantom all cost the same, so the choice in Sukma depends on the vehicle in front of you. Three questions help. How far is the tank from where the tracker will sit? Is the tank steel or plastic? And would you rather avoid replacing a sensor battery later? For an owner with one or two vehicles, getting this right first time matters.

Omnicomm is the wired sensor. It runs on the vehicle's power and sends its reading to the tracker by cable, so there is no battery at all. A tipper whose tank sits under the chassis near the cabin is the obvious match: the cable run is short, and once calibration is done the sensor needs little attention, which suits a vehicle working far from any workshop.

Mercetech and Mielta Fantom are wireless. Mercetech uses Bluetooth and has an internal battery, which helps where the tank sits far from the tracker, as on a bus or a long truck. Mielta Fantom uses Bluetooth 5.0, carries its own battery, senses tilt and has a steel flange that fits steel or plastic tanks; it is configured through Mielta's mobile app. Pickups, Boleros and tractors with plastic tanks often point to it.

In all three cases the probe goes in from the top and is cut to the tank's depth, so BearTech confirms the model and probe length after seeing the tank or a clear photo. Batteries in the wireless sensors are consumables outside the warranty. If the listed model is not available, a comparable one may be supplied, and you will be told beforehand.

Even a small Sukma operation often has more than one person who needs the fuel figures. A contractor may be at a site while his supervisor handles the depot and a part-time accountant prepares bills. A hostel may have a warden who books the bus and an office clerk who pays for diesel. Trakzee Premium lets the owner create extra user logins with separate passwords, so each person reads the same record without the main password being shared.

The owner needs only the unusual. A brief look each morning at sudden falls and new refills, and a weekly comparison of each vehicle with its own earlier weeks, is usually enough. A tipper on site work and a pickup on haat rounds will never match each other, so comparing each with its own past is the fair test.

The supervisor reads fuel next to position. Before tippers leave the depot, he can see which ones need diesel first. If an alert arrives while a vehicle is parked at a distant site, he can find it on the map, call the driver and write a note for the owner. Where signal is patchy, he knows a gap in data is not a loss of diesel and waits for fresh readings before deciding anything.

The accountant matches slips to refills. Each refill on the platform carries a date, a time and a rise in litres, which can be ticked against pump slips or drum issues once a week. Anything unmatched becomes a polite question rather than an argument. Monthly consumption and mileage by vehicle can be exported for the bills, giving the owner and the accountant one set of numbers.

No fuel monitoring system reads diesel perfectly, and this one is no exception. BearTech gives the accuracy as about 95% on a sound tank after proper fitting and calibration. That is good enough to see refills, compare trips and catch sharp falls. It is not a laboratory measurement, and it should not be used to argue over a single litre.

Sukma's roads explain most of the wobble. A tipper bouncing over a fresh murram surface, or a pickup crossing a rough causeway, sends diesel sloshing, and the graph jumps while the vehicle moves. A bus parked on a slope at a village halt, or a tractor on a raised paddy bund in the Sabari valley, holds its tank at an angle, and the probe sees a different level. In none of these cases has fuel gone missing.

The tank and the fuel add their own effects. A dented or oddly shaped tank, a patched seam, water or sludge at the bottom, or uneven diesel quality can all move the figure away from the truth. After any welding or tank change, calibration must be done again. On forest stretches where Airtel signal fades, the live view simply pauses until the tracker reconnects; a pause is not a loss.

The practical rule is to compare readings taken while the vehicle is parked on level ground, before and after an event, and to treat jumps on the move as noise. Remember that wireless sensor batteries are consumables outside the warranty, and that BearTech gives no returns, refunds or exchanges, so tank details and doubts should be cleared before ordering.
