Fuel Monitoring System in Chhota Udaipur: Diesel Records for Mine Tippers and Furniture Tempos

A fuel monitoring system in Chhota Udaipur has to suit a district of hills and rivers. It is the eastern edge of Gujarat, with Vadodara to the west, Panchmahal to the north-west, Narmada to the south and Alirajpur in Madhya Pradesh across the line to the east. The Orsang and Heran cut through the hills, and roads bend around them to reach Bodeli, Sankheda, Jetpur Pavi, Kavant, Nasvadi and the district town.

Minerals set the heaviest pattern. Fluorspar and dolomite leave the workings around Ambadungar by tipper, cycling between pit, weighbridge and buyer. Each cycle has loading time, road time and queue time, and much of the diesel goes into the waiting. Bodeli's industrial area draws goods and staff, and a railway runs from Vadodara to Chhota Udaipur for some of the freight.

Smaller loads fill the rest. Sankheda's lacquered furniture goes out in tempos and small trucks to Vadodara and beyond. Maize, cotton and pigeon pea come in on pickups from autumn into winter, and forest produce rides in mixed loads. Weekly haats and market days at Chhota Udaipur, Bodeli and Kavant bring extra pickups, tractors and jeeps on fixed days. School and hostel buses run long circuits to remote hamlets.

The monsoon rearranges everything. From about June to September the rivers swell, hill tracks soften and low causeways can close for hours or days, so mining slows and long runs are rescheduled. In the dry months mines and construction work at full speed. Through every season the owner, often in Vadodara, cannot see the tank, and a dated level record for each vehicle is how that diesel comes back into view.

The tipper's diesel tank is a steel box on the frame, filled through a cap on top. On fitting day the executive opens a hole in that top face and lowers a probe into the diesel, cutting it so it reaches just short of the bottom. Once sealed, the probe stays in the fuel permanently. Nothing on it moves, which is useful in a vehicle that shakes all day on quarry tracks.

The probe senses capacitance: as more of it is covered by diesel, its electrical value shifts, and its head turns that into a level. The level reaches the Teltonika FMB920 in the cab, through a cable for Omnicomm or by Bluetooth for Mercetech and Mielta Fantom. The tracker joins it with the tipper's position, speed and ignition, and transmits over its Airtel SIM to Trakzee Premium whenever signal allows.

In the app, the owner sees the tipper as a marker on the map with a fuel line next to it. The line falls in small steps through the day's cycles, stays nearly flat in the weighbridge queue, jumps at each refill with time and place attached, and drops in a sharp step if diesel leaves the tank while the tipper stands, which also raises an alert. Daily and per-trip mileage and consumption reports come from the same data.

Calibration is the final link. On fitting day the executive matches raw probe values with known quantities of diesel in that tank, so the line reads in litres. If the tank is later swapped, welded or the probe removed, calibration has to be redone; inform BearTech first. In valleys where the network drops, the live view simply waits until the tipper reaches signal again.

The reading is good to about 95% on a sound tank after proper fitting and calibration. That makes it a sturdy working guide, but not a laboratory measurement, and Chhota Udaipur's roads show its limits more often than flat districts do. Slope, sloshing, the tank's condition and shape, and the diesel's quality are the four things that move it. Knowing them keeps alerts in proportion.

On the bends around the hills and on quarry tracks, diesel surges inside the tank, so the moving line wobbles. A tipper parked on a ramp at the pit, a pickup tilted on a village slope or a bus standing on a sloping roadside near a causeway shows a different level from the same tank on flat ground. Such shifts are motion and tilt, not diesel leaving the tank.

Tanks and fuel matter as well. Old tanks with dents or patches, odd shapes, and diesel carrying water or sediment all bend the reading. Signal is a separate issue: in valleys and around river crossings Airtel coverage can drop, and the live view pauses until the vehicle reaches signal again. A gap in the graph is a network pause and should not be read as a loss.

The rule that follows is simple. Judge refills and falls from readings taken with the vehicle parked on level ground, before and after the event, and treat the line on the move as approximate. The batteries in wireless sensors are consumables outside the warranty. And because BearTech does not accept returns, refunds or exchanges, send tank details and a photo before ordering. A short call beforehand clears most doubts.

An alert means the level fell faster than running explains, nothing more. Suppose one arrives in the evening for a tipper parked at the pit. Start with what the screen shows: was the ignition off, was the tipper stationary, and was it standing on the level or on the ramp of the loading area? A tilted tank alone can produce an alert.

Then the supervisor, who is close by, can walk over or phone the driver and ask calmly what happened. Perhaps diesel was drawn into a drum for the loader, a mechanic drained the tank to clear a filter, or the tipper was parked on a slope. Next, compare the refill log with the pump slips and the site's drum register for the day. A quick photo of the drum register on WhatsApp helps the owner in Vadodara follow along. Most alerts end here.

When they do not, read the time and place together. A fall at midday in the busy weighbridge queue raises different questions from one at midnight on a quiet stretch towards the Madhya Pradesh side. Save a screenshot showing the level before and after, the spot, the ignition record and the halt duration, so any follow-up talk works from the same facts.

Finally, write the outcome in a register: date, vehicle, driver and what was decided. After a month the entries show whether falls are scattered or keep returning to one vehicle or one stopping place. Tell drivers openly what the system does: it records levels and raises alerts, but it cannot lock a tank or physically stop anyone taking diesel. Physical locks and site rules remain the owner's job.

One vehicle first. The Complete Package costs ₹19,999 plus GST for year one and covers the FMB920 tracker, a fuel level sensor of your choice, fitting, the Trakzee Premium login, the Airtel SIM and a year of warranty with AMC. Renewal from year two is ₹3,000 per vehicle per year. Plans listed at ₹22,999 for two years and ₹25,999 for three give the same totals.

Now a sample mixed fleet, chosen only to show the arithmetic: three mineral tippers, two Sankheda furniture tempos, one maize pickup and one hostel bus. Seven packages make ₹1,39,993 for year one. Seven renewals of ₹3,000 add ₹21,000 each year, bringing the total to ₹1,60,993 after two years and ₹1,81,993 after three, which is seven times ₹25,999. These are straight multiplications of the published per-vehicle prices.

The executive's travel and stay come on top, paid by you and stated before ordering. Seven vehicles in one visit share a single journey, so it pays to gather them in one place, perhaps at the quarry yard or a Bodeli depot. A tipper or bus with a second tank needs separate mention, as the package covers one sensor per vehicle.

Savings are not promised here. What seven sensors are worth depends on what their records show: diesel per cycle that is steady across tippers or one that stands out, furniture deliveries whose fills match their slips, a hostel bus whose litres per circuit hold firm. Each outcome tells you something. Monsoon months and dry months will look different, so give the records a full season. Compare the three-year figure with your own diesel bills, then decide, and call 97526 44035 for an exact quote.
