Fuel Monitoring System in Jalna: Diesel Logs for Steel and Mosambi Trucks

Picture a truck that carries TMT bars from a re-rolling mill on the edge of Jalna city to a dealer in Beed. Its diesel tank is a steel box bolted under the chassis. During fitting, a small opening is cut into the tank's top face and a measuring probe, trimmed so it nearly touches the floor of the tank, is lowered in and sealed. From that moment part of the probe is always bathed in diesel, and how much of it is covered depends on how full the tank is.

The probe senses that covered length electrically and converts it into a level. It passes this level to the Teltonika FMB920 mounted in the cabin, either along a cable with Omnicomm or wirelessly over Bluetooth with Mercetech and Mielta Fantom. The tracker joins it with what it already knows, namely the truck's location, speed and ignition state, and sends the combined record across the Airtel network to the Trakzee Premium platform at regular intervals.

On the owner's phone, the truck's diesel becomes a number in litres and a line plotted over time. Climbing the gentle grades towards Beed, the line drifts steadily lower. A refill at a highway pump shows as an abrupt rise with the hour and the place beside it. A sharp fall while the truck is parked appears as a drop and triggers an alert. Daily and trip-wise consumption reports are built from that same stream of readings.

None of this means much without calibration. On fitting day the executive matches the probe's output to known quantities of diesel in that particular tank, so the screen reads in litres for that tank alone. Swap the tank, weld a crack or pull the probe out for any reason, and calibration has to be repeated. A quick call to BearTech before such work keeps the record honest.

Jalna lies on the Marathwada plains, with Chhatrapati Sambhajinagar to the west, Parbhani to the east, Buldhana to the north and Beed to the south. The Godavari runs along its southern edge, and the Dudhna crosses the flat, dry farmland. Cotton, soybean, pulses and sweet lime grow across the tehsils of Bhokardan, Jafrabad, Badnapur, Ambad, Ghansawangi, Partur and Mantha, and every harvest has to be carried somewhere by a diesel engine.

On the edge of Jalna city, steel re-rolling mills and seed companies send trucks out in every season. Rods and coils go to dealers across the region, while packed seed travels to distributors in many states. The dry port adds container traffic. These trucks work in tight loops of loading, weighing, delivering and returning, and each loop includes waits with the engine running at a plant gate or a weighbridge.

Roads make long runs easy. The Mumbai-Nagpur Samruddhi expressway crosses the district, older highways link Jalna with Sambhajinagar, Beed and Parbhani, and the railway from Manmad towards Secunderabad stops at Jalna station. A truck can reach Pune or Nagpur within a working day. After the monsoon, roughly from October to December, cotton and soybean pour into ginning units and mandis, and pickups make several trips a day from field to yard.

Then come the seasonal and passenger vehicles. Mosambi trucks drive through the night to reach city markets by morning. In dry summers, water tankers in some years run repeated shuttles to villages. Buses and cabs connect Jalna with Sambhajinagar, Parbhani and Pune, and visitors travel to the Rajur Ganpati temple in Bhokardan tehsil on special days. Across all of them, diesel is spent far from the person who pays for it.

BearTech states the accuracy as about 95% on a sound tank, after correct fitting and calibration. That is a working figure for everyday decisions about refills, consumption and alerts. It is not the precision of a laboratory meter, and nobody should settle a commercial dispute by quoting one reading to the last litre. Several ordinary conditions move the number away from the true quantity, even on Jalna's largely flat roads.

Motion is the most common. A loaded truck braking at a toll plaza on the expressway, or a pickup jolting over a farm track near Ghansawangi, throws diesel forward and back, and the graph wobbles while the vehicle moves. Slope matters too: a tanker parked on the sloping approach to a village well, or a tractor left on a field embankment, tilts its tank so the fuel leans away from the probe.

The tank and the fuel play their part. Dents, patched seams and irregular shapes change how level relates to litres. Water and sediment at the bottom of an old tank, or diesel of poor quality, can also shift readings. If a tank has been repaired or swapped, recalibration is needed. Network is usually steady on Jalna's highways, but where coverage dips the live view simply pauses until the tracker reconnects, which says nothing about the diesel.

The working rule is to judge refills and losses from readings taken while the vehicle is parked on level ground, comparing before and after, rather than from a jump recorded on the move. Also remember that wireless sensor batteries are consumables outside the warranty, and that BearTech does not accept returns, refunds or exchanges, so tank questions belong before the order, not after it.

An alert for a sudden drop does not mean someone has taken diesel. It means the level fell faster than ordinary running would account for, and that deserves a look. Start by asking where the vehicle was. Open the map and the ignition history: a truck at a weighbridge, a pickup on a sloping orchard track or a tanker at a filling point each raise different possibilities from one parked silently beside a roadside dhaba.

Ask whether the ground was level. Readings taken on a slope can drop simply because diesel moved within the tank. If the vehicle has since been moved to flat ground, compare the level there with the level before the event. Then ask the driver. A short, polite call, made while he still remembers the hour, often clears things up: a jerry can used for a stranded tractor, a mechanic draining the tank, a refill not yet logged.

Ask whether the paperwork agrees. Put the alert beside the pump slip and the refill list for that day. A slip timed long before or after the recorded rise, or a rise that never had a slip, is worth noting. Look at the hour and the place together: a fall during busy daytime unloading is different from one at an isolated halt at two in the morning. Compare with the same vehicle's earlier weeks too.

Finally, record the outcome in a simple register: date, vehicle, driver, explanation, closed or open. After a month the register shows whether alerts cluster around one vehicle or one stop. Through all of this, keep the system's scope in mind. It reports levels, refills and drops; it does not lock a tank and cannot keep anyone away from the fuel. Locks, yard discipline and the choice of halts remain with you.

One vehicle first. The Complete Package costs ₹19,999 plus GST and covers year one: the FMB920 tracker, a fuel level sensor of your choice, fitting, the Trakzee Premium login, the Airtel data SIM and a year of warranty with AMC. From year two, the renewal is ₹3,000 per vehicle per year to keep the software and SIM running. That is why the 2-year plan is listed at ₹22,999 and the 3-year plan at ₹25,999.

Now a sample fleet, picked only to illustrate the sums: seven trucks carrying steel from Jalna mills. Year one is 7 × ₹19,999 = ₹1,39,993. Renewal is 7 × ₹3,000 = ₹21,000 a year. The running total after year two is ₹1,39,993 + ₹21,000 = ₹1,60,993, and after year three ₹1,60,993 + ₹21,000 = ₹1,81,993, which matches 7 × ₹25,999 exactly. These are plain multiplications of the listed prices.

Travel and stay for the executive's visit from Bhopal come on top of these figures. They are paid by the client and quoted before ordering, and fitting all seven trucks in one visit keeps them to a single journey. The package covers one sensor per vehicle, so a truck with twin tanks needs a separate quote. Fleet prices can be confirmed on 97526 44035 before you fix a budget.

These numbers are costs, not a forecast of savings. Whether the records justify them depends entirely on what they turn up in your own fleet: steady, well-explained figures, or refills and falls that nobody can account for. A sensible test is to set the three-year total next to one month of the fleet's diesel bills and the hours spent chasing pump slips, then judge for yourself.
