Fuel Monitoring System in Patan: Tank Data for Cumin Trucks and College Buses

Many Patan owners ask about money first, so here it is. A single vehicle pays ₹19,999 plus GST in the first year. That covers its FMB920 tracker, one fuel sensor, the installation, a Trakzee Premium login, the Airtel data SIM and twelve months of warranty with AMC. The second and third years each cost ₹3,000 in renewal. Totalled, one vehicle reaches ₹22,999 after two years and ₹25,999 after three, the same as BearTech's 2-year and 3-year plans.

Now picture a Patan trader with five diesel vehicles: two cumin trucks, a castor pickup, a college bus run on contract and a site pickup near Charanka. Five packages make ₹99,995 in year one. Five renewals add ₹15,000 in every following year. Total spend therefore reads ₹1,14,995 at the end of the second year and ₹1,29,995 at the end of the third, with one sensor in each vehicle.

One cost sits outside those totals. Because Patan is outside Bhopal, the executive's travel and stay are paid by the client, and BearTech tells you the amount before you order. Five vehicles spread between Radhanpur, Patan and Charanka should be gathered at one or two places on agreed days, so the visit stays short. A vehicle with two tanks is quoted separately.

Do these numbers pay back? Only your records can say, and no saving is promised. Lay the three-year total beside a normal month of diesel for the five vehicles, and beside the hours lost to slips, yard queues and long silent trips across dry country. If the records show steady use, you gain certainty. If they show gaps, you gain dates and places to ask about.

Consider a truck that carries cumin from Santalpur to the Unjha yard. Its diesel tank is steel, bolted under the chassis. During fitting, a hole is cut in the top of the tank and a probe is inserted, trimmed to the tank's depth and sealed. The probe senses capacitance, which shifts as diesel covers more or less of it. No float, no moving part, nothing to jam on a dusty road.

The probe's reading passes to the Teltonika FMB920 tracker in the cab, through a cable for Omnicomm or by Bluetooth for Mercetech and Mielta Fantom. The tracker already logs the truck's position, speed and ignition. It sends the combined data over an Airtel data SIM to Trakzee Premium, where the calibration made at fitting converts raw readings into litres that anyone in the business can follow.

On the owner's phone, the level shows as a number and a line through the day. A refill at a pump on the Radhanpur road appears as a sharp rise with time and place. The hours spent in the Unjha queue show as a slow decline if the engine idles, or a flat line if it is off. A steep fall with no driving to explain it triggers an alert.

Reports summarise the same readings: litres per day and per trip, mileage per vehicle and refills for any period. The phone is enough for a morning check; a computer helps compare trucks across a whole cumin season. Calibration is tied to one tank, so a replaced or welded tank, or a probe refitted after repair, needs fresh calibration. Tell BearTech in advance so the numbers stay trustworthy.

On a sound tank, after proper fitting and calibration, the reading is about 95% accurate. It follows refills, consumption and unusual falls well enough to guide decisions. It is not a laboratory measurement and should not be used to sell diesel or settle a legal claim. Treat it as a well-founded estimate that sharpens your questions. Owners who read it this way find it steady and useful.

Several things push the figure around. On rough village tracks the diesel sloshes. A pickup parked on a bund or a site vehicle on uneven ground near Charanka tilts its tank. Long hot days on dry roads can make readings drift a little compared with cool mornings. Dented or rusty tanks, unusual tank shapes and diesel with water or dirt in it pull the reading away from the true quantity.

So compare readings taken at rest. To judge a refill or a loss, take the levels before and after with the vehicle parked on level ground, ideally at similar times of day. Ignore the wobble during movement and follow the trend over hours. After a fill, wait a few minutes for the diesel to settle before trusting the new figure.

Coverage and batteries are the final limits. Data travels on an Airtel SIM, and on stretches near Santalpur and the Rann edge the bars can vanish. The live view then pauses until the tracker reconnects; that gap reflects coverage, not the driver. In the monsoon, waterlogged low roads may hold vehicles for hours. Wireless sensor batteries are consumables outside the warranty. Tell us which roads go quiet so the gaps make sense from the start.

In Patan, the person who owns the vehicles is often busy with something else: a cumin trading business, a college, a contracting firm. A transport in-charge sends vehicles out each day, and an accountant pays the pump bills. Trakzee Premium lets the owner add extra user logins, so both can read the same fuel record without the owner's password, each limited to the vehicles they handle.

The owner wants only the unusual. A few minutes each morning with sudden-drop alerts, the refill log and the week's consumption shows whether any truck burned noticeably more than its twin on the Unjha run, or whether a refill exceeded the tank. Those go on a list for a quiet talk; the rest can wait. The phone app is enough for this daily glance.

The in-charge reads diesel with movement. Before a bus sets off on a long village round, the in-charge checks the level will last. On yard days, the halt report shows which trucks spent hours queuing, and the fuel line shows whether engines ran. For site pickups near Charanka, it shows how long each stood at the site and how much diesel it used there.

The accountant works from dates and litres. Each refill carries a time and a rise in level, so pump slips can be ticked off in order. A slip with no matching rise, or a rise far short of the slip, becomes a polite question. Monthly mileage and consumption per vehicle go into the books beside the bills, and the trading accounts finally match the tanks.

When the alert arrives, read it for what it is: the level fell faster than ordinary running explains. It is a question, not an answer. Open the map and note where the vehicle stood, whether the engine was on, and the levels before and after. Save a screenshot, especially if the vehicle is far out near the Rann where calls drop.

Rule out the routine causes. A pickup parked on a bund, a truck on a sloping yard edge or a site vehicle on rough ground can show a false fall. Rough tracks make diesel slosh. A mechanic may have opened the tank, or it may have been topped up from a drum. If the line falls and returns within minutes, tilt or movement is the likely reason.

If the level stays down while the vehicle stands still on level ground, call the driver calmly and ask what happened at that place and time. Have the latest pump slip beside you. Explanations are often ordinary: diesel moved to a site generator, a leaking pipe, fuel lent to a stuck vehicle on a lonely road. Check what you hear against the route history. A calm tone keeps the conversation useful.

Keep a register: date, vehicle, place, explanation, outcome. After a month it shows whether drops are scattered or keep returning to one vehicle, driver or site. Remember the limits: the system records and warns, but it cannot lock a tank or physically stop diesel being drawn. Lockable caps, guarded site parking and clear rules for transferring fuel remain your own responsibility. Share the register with whoever pays the diesel bills each month.
