Fuel Monitoring System in Gandhinagar: Diesel Level on Your Phone

Gandhinagar vehicles live a stop-start life. A staff cab leaves a sector in the morning, collects riders, runs towards Ahmedabad or across to Infocity, waits outside a building, and repeats the pattern in the evening. Few kilometres are covered in a long day, yet the engine may run for hours. That makes diesel use hard to judge from distance alone. A reading taken from inside the tank and shown beside the location fills that gap, because the owner sees litres leaving during the waits as well as during the runs.

Picture a contractor who supplies cabs to several offices in the capital. He pays for diesel, the driver fills the tank, and the monthly claim is built on kilometres. Without tank data, a claim that looks reasonable on paper can hide a vehicle that burned more than it should have. With a level record, the contractor can set one day's litres next to that date's kilometres and see which cabs behave consistently and which deserve a polite conversation. Nothing dramatic is needed, only a habit of looking.

Ahmedabad's airport is about 18 km away, a run that a hired vehicle may make several times a week. Repeated trips give the owner a natural yardstick: the same journey should use a similar amount of diesel each time. When one vehicle's tank falls clearly further than its sister vehicles on identical duty, the fuel graph points to the date and hour, and the route history shows whether there was a detour or a long wait with the engine on.

A word on fit before you plan anything. The package is meant for diesel tanks with an opening that lets the probe go in from the upper side. Many city cars run on petrol or CNG, and for those you should call 97526 44035 first so we can say honestly what is possible. Diesel vans, minibuses, college buses and goods vehicles are the natural candidates. The tracker also gives the usual location, ignition and overspeed reports, so the fuel reading is one extra layer on a vehicle you may already want to follow.

Set one fixed hour each week, perhaps Monday before the first pick-up, and open the fuel report for the last seven days. For each vehicle note the litres added, the kilometres run and the resulting mileage. You do not need to study every line. Sort the list by mileage and look hard at the two ends, the vehicle that does unusually well and the one that does unusually badly. The first may have a correct driver or a short route; the second needs a question.

Take the question to the driver with facts, not accusations. For instance, tell him that on Thursday evening the level fell by a clear amount while the cab sat parked near a campus gate, and ask what happened. There may be an ordinary reason such as a transfer to another vehicle, a service wash or a pump top-up done elsewhere. A fair conversation keeps drivers on your side, and the record keeps everyone honest without anyone being shouted at.

Dispatchers can build fuel into the shift itself. Ask staff-transport drivers to refill at the start of duty or at a fixed pump, so every refill entry lines up with a known shift. Campus buses at IIT Gandhinagar and GNLU run fixed timings, which makes them easy to compare: the same bus on the same round should show a similar fall in level from one day to the next. A bus that drifts away from its own pattern is the one to inspect.

Keep a short log with the date, the vehicle, what the graph showed, what the driver said and what you decided. After a month it becomes your own reference and tells you which vehicles need a mechanic and which need a reminder. Use sub-user logins so a transport in-charge sees only the vehicles he manages while the owner sees the whole fleet, and ask BearTech to help set the roles up when the account is activated.

Refill detection turns a vague habit into a record. When diesel is added, Trakzee Premium notes the time, the location and how far the level rose. For a cab or van that works the Ahmedabad shuttle, this means you can ask a simple question after every fill: did the tank receive what the pump slip says was delivered? If the slip shows a certain quantity and the rise in level is close to it, the entry is settled in seconds.

Expect small differences. With accuracy of about 95% under normal conditions, a few litres of mismatch on a large tank is ordinary, and readings taken while the vehicle is rocking at the pump can be a little rough. The better check is a pattern. If one driver's fills regularly show a rise noticeably below the slip while other drivers on the same duty do not, you have a reason to ask where the pump stood and who was present.

Location helps here. The refill entry carries a place along with the quantity, so you can see whether the driver filled in Gandhinagar or on the Ahmedabad side and whether that matches the pump you expected him to use. Where a contractor has an arrangement with one fuel station, an entry from a different place is worth a question. Do not assume wrongdoing; a closed pump or a queue may explain it, and the driver can say so.

Pair refill entries with the reports that follow. After a fill, the fall in level over the next days, set against the kilometres run, gives you the true mileage of that tank of diesel. Accounts staff can then reconcile fuel bills against recorded fills, and the owner can spot a vehicle that needs servicing when mileage slides over several weeks. Keep the pump slips for a month at least so you can look back when a number surprises you.

Think of the system as a relay of four hands. The probe sits inside the tank and senses how high the diesel stands. The Teltonika FMB920 collects that figure and the vehicle's position together. An Airtel SIM carries both to the platform, and Trakzee Premium draws them as a level, a map point and a graph. Each reading is stamped with a time and a place, which is what makes it useful on a map-heavy city like Gandhinagar.

Because location travels with the reading, fixed points become meaningful. Draw geofences around the Sector 14 railway station, the Mahatma Mandir area, the IIT Gandhinagar campus or a sector depot, and every rise or fall in diesel can be read against a named place. A level that drops while a bus is inside its own depot fence tells a different story from one that drops while the vehicle stands at an unexpected spot across town.

The wired and wireless sensors differ only in how the reading reaches the tracker. With the Omnicomm, a cable carries it into the analog input. With Mercetech and Mielta Fantom, Bluetooth does the same job. After that the data path is identical, so reports look the same whichever sensor you pick. The tracker works on 12 V and 24 V supplies and has a backup battery for brief power loss. Nothing needs switching on by the driver; the whole chain starts working once the vehicle is powered.

Finally, remember what the probe measures: the height of diesel in that tank, then converted into litres through calibration. If the tank is dented, the shape changes and the conversion drifts, which is why calibration is done at fitting and repeated after changes. The sensor does not know why the level moved. It tells you when and where, and you supply the explanation by checking the pump slip, the route and the driver's account.

Mileage only means something when like is compared with like. A cab's kilometres per litre on the Sarkhej-Gandhinagar highway will differ from the same cab crawling through sector roads with frequent halts, so never compare a highway day with a campus day. Group vehicles by duty first. Staff cabs against staff cabs, campus buses against campus buses, goods vans against goods vans, and each vehicle against its own earlier weeks, give far more honest numbers than a single fleet average.

The calculation is easy once both records exist. The distance report gives kilometres for the period, and the fuel report gives litres used between two readings or across refills. Divide one by the other. Use a period of at least a week so that a single odd fill does not distort the answer, and avoid mixing in days when the tank was filled just before and drained just after, which makes the arithmetic untidy.

Idling deserves its own line. Gandhinagar's summer heat can push drivers to leave engines running for cooling while they wait, and sector-to-sector duty has many such waits. Trakzee's stoppage reports show how long a vehicle stood, while the fuel graph shows what that wait cost. If two cabs on identical routes show similar kilometres but one burns visibly more diesel, compare their stoppage hours before blaming the engine. Repeat the same comparison in May and again in July before concluding that anything has really changed.

Use the Ahmedabad-Vadodara highway and the state and district roads across Kalol, Dahegam and Mansa as separate categories when a vehicle serves them. Long runs on open roads tend to give steadier mileage than short city hops. Over several weeks, a slow slide in mileage with no change in route is the early signal that a vehicle needs tyre pressure, filter or injector attention, long before it breaks down on the road.

The owner wants the big picture, quickly. A weekly glance at the fleet list shows each vehicle's current level, last refill and any fuel drop alert. If something stands out, he opens the fuel graph, looks at the shape and the timing, and then the route history. This takes minutes and gives him a view of cabs, buses and vans he cannot be physically beside, which matters when vehicles are working across sectors and towards Ahmedabad.

The transport manager lives in the daily detail. His sub-user login lists only the vehicles he looks after, with live location, the level, the trip and stoppage reports and alerts. He uses the fuel drop alert as a prompt to phone the driver, check the position and note the explanation. He can also review the refill entries each morning and flag any missing or odd fill before it becomes a month-end argument.

Accounts needs dates and totals. The fuel and trip reports give consumption and mileage per vehicle for a period, which can be matched with pump bills and with the contractor's kilometre claims. Where a claim, a fuel bill and the report do not agree, accounts can send a short query to the manager with the vehicle and the date. Remember the reading is for monitoring and not a legal measure of fuel.

All three can use the same Trakzee Premium account on the phone app, on Android or iOS, and on a computer. A short weekly meeting around one screen works well: the manager explains the outliers, accounts confirms the bills and the owner decides the actions. Keep the agenda small, a few vehicles at a time, and the habit will last. Ask us on 97526 44035 if you want help setting up the logins or reports.
